Description of the Related Art
Neoplasia and immune system
A neoplastic disease state commonly referred to as cancer is believed to be caused by a single cell with uncontrolled growth. Uncontrolled growth states are typically caused by a multi-stage process in which a series of cell systems fail, resulting in the development of neoplastic cells. The resulting neoplastic cell rapidly multiplies itself to form one or more tumors, which ultimately can result in the death of the host.
Since progenitors of neoplastic cells share the genetic material of the host, neoplastic cells are mostly not attacked by the host immune system. During immune surveillance, in the process the host immune system monitors and localizes foreign substances, and neoplastic cells appear to the host immune surveillance machinery as "self cells.
Virus and immune system
In contrast to cancer cells, viral infection involves the expression of apparently non-self antigens. As a result, the immune system successfully addresses many viral infections with minimal clinical sequelae. In addition, effective vaccines have been developed for many of those infections that cause severe disease. Various vaccine approaches have been successfully used to combat a variety of diseases. These methods include subunit vaccines, which consist of individual proteins produced by recombinant DNA techniques. Despite these advances, the selection and effective administration of the smallest epitopes for use as viral vaccines remains problematic.
In addition to the difficulties associated with epitope selection, there is a problem with viruses that have evolved to evade the ability of the host immune system. Many viruses, especially those that establish persistent infections, such as members of the herpes and poxvirus families, produce immune modulatory molecules that allow the virus to evade the host immune system. The effect of these immunomodulatory molecules on antigen presentation can be overcome by targeting selected epitopes for administration as immunogenic compositions. To better understand the interaction of neoplastic and virally infected cells with the host immune system, the system components are discussed next below.
The immune system serves to distinguish molecules endogenous to an organism (the "self" molecules) from substances that are foreign or foreign to the organism (the "non-self" molecules). Based on the components that mediate the response, the immune system has two types of adaptive responses to foreign objects: humoral responses and cell-mediated responses. Humoral responses are mediated by antibodies, while cell-mediated responses involve cells classified as lymphocytes. Recent anticancer and antiviral strategies have focused on mobilizing the host immune system as a means of anticancer or antiviral therapy or therapy.
The immune system functions in three phases to protect the host from foreign objects: an identification phase, an activation phase and an effect phase. In the recognition phase, the immune system recognizes and signals the presence of foreign antigens or invaders within the body. The foreign antigen may be, for example, a cell surface marker derived from a neoplastic cell or a viral protein. Once the system detects an invader, antigen-specific cells of the immune system proliferate and differentiate in response to invader-triggered signals. The final phase is the effector phase, in which effector cells of the immune system respond and neutralize the detected invader.
A series of effector cells carry out an immune response to an invader. One type of effector cell, the B cell, produces antibodies that target foreign antigens encountered by the host. In conjunction with the complement system, antibodies direct the destruction of cells or organisms that carry the target antigen. Another class of effector cells are natural killer cells (NK cells), a class of lymphocytes that have the ability to recognize and destroy multiple virally infected cells as well as malignant cell types simultaneously. The method by which NK cells recognize target cells is not well understood.
Another class of effector cells, T cells, have members classified into three subclasses, each of which plays a different role in the immune response. Helper T cells secrete cytokines that stimulate the proliferation of other cells necessary to produce an effective immune response, while suppressor T cells down-regulate the immune response. The third type of T cell, cytotoxic T Cells (CTL), is capable of directly lysing target cells presenting foreign antigens on its surface.
Major histocompatibility complex and T cell targeting
T cells are antigen-specific immune cells that play a role in response to specific antigen signals. B lymphocytes and the antibodies they produce are also antigen-specific entities. However, unlike B lymphocytes, T cells do not respond to antigens in free or soluble form. In order for a T cell to respond to an antigen, the antigen needs to be processed into a peptide, which is then bound to a presentation structure encoded in the Major Histocompatibility Complex (MHC). This requirement is termed "MHC restriction" and is the mechanism by which T cells distinguish "self" from "non-self" cells. If an antigen is not displayed by a recognizable MHC molecule, the T cell will not recognize and act on the antigen signal. Specific T cells that bind peptides that recognize MHC molecules bind to these MHC-peptide complexes and enter the next stage of the immune response.
There are two classes of MHC, MHC class I and MHC class II. T helper cell (CD 4)+) Cytolytic T cells, which interact mainly with MHC class II proteins (CD 8)+) Mainly interacting with class I MHC proteins. Both classes of MHC proteins are transmembrane proteins, most of which are structured on the outer surface of cells. In addition, two classes of MHC proteins exist in itThey all have a peptide binding cleft (binding cleft) on their exterior. Small fragments of endogenous or exogenous proteins are bound in the cleft and presented in the extracellular environment.
Cells called "professional antigen presenting cells" (pAPCs) display antigens to T cells using MHC proteins, but additionally express various costimulatory molecules, depending on the specific state of differentiation/activation of pAPCs. When specific T cells that recognize MHC protein-binding peptides bind to these MHC-peptide complexes on pAPCs, specific co-stimulatory molecules acting on the T cells direct the differentiation/activation pathway taken by the T cells. That is, the costimulatory molecule affects how T cells will act on antigen signaling when it enters the next stage of the immune response in future encounters.
As discussed above, most neoplastic cells are ignored by the immune system. A great deal of effort is being expended in efforts to control the host immune system to help fight the presence of neoplastic cells in the host. One such area of research involves formulating anti-cancer vaccines.
Anti-cancer vaccine
The immune system of a patient is one of the various weapons available to oncologists in fighting against cancer. Work has been done in various efforts to combat the immune system against cancer or neoplastic disease. Unfortunately, the results to date have been largely disappointing. One area of particular interest relates to the production and use of anti-cancer vaccines.
To produce a vaccine or other immunogenic composition, it is necessary to introduce into a subject an antigen or epitope against which an immune response can be raised. Although neoplastic cells are derived from normal cells and are therefore essentially identical at the genetic level to normal cells, many neoplastic cells are known to present tumor associated antigens (TuAAs). In theory, the subject's immune system can utilize these antigens to recognize these antigens and attack neoplastic cells. However, in practice neoplastic cells often appear to be ignored by the host's immune system.
Many different strategies have been developed in an attempt to produce vaccines with activity against neoplastic cells. These strategies include the use of tumor-associated antigens as immunogens. For example, U.S. patent No.5,993,828 describes a method of generating an immune response against a specific subunit of a Urinary Tumor Associated Antigen (urory Tumor Associated Antigen) by administering to a subject an effective amount of a composition comprising inactivated Tumor cells having a Urinary Tumor Associated Antigen on the cell surface and at least one Tumor Associated Antigen selected from the group consisting of GM-2, GD-2, fetal Antigen and melanoma Associated Antigen. Thus, this patent describes the use of whole killed tumor cells as immunogens in anti-cancer vaccines.
Another strategy for using anti-cancer vaccines involves administering a composition containing the tumor antigen alone. In one approach, the MAGE-A1 antigenic peptide is used as an immunogen (see Chaux, P., et al, "Identification of Five MAGE-A1 Epitopes recognited by Cytolytic TLymphates Obtained by In Vitro Stimulation with a degraded cell transformed with MAGE-A1," J.Immunol., 163 (5): 2928-2936 (1999)). There have been several therapeutic trials using MAGE-a1 peptide for vaccination, although the efficacy of this vaccination therapy is limited. In Vose, J.M., "Tumor antibodies Reccognized by T Lymphocytes," 10thThe results of some of these assays are discussed in the European Cancer Conference, Day 2, Sept.14, 1999.
In another example of a tumor associated antigen used as a vaccine, Scheinberg et al used 5 injections of a class I related bcr-abl peptide and a helper peptide plus the adjuvant QS-21 to treat 12 Chronic Myelogenous Leukemia (CML) patients who had received Interferon (IFN) or hydroxyurea. Scheinberg, D.A., et al, "BCR-ABL BreakPoint Derived Oncogene Fusion Peptide Vaccines in Patients with Chronic Myelogenogens Leukemia (CML) [ Abstract 1665],American Society of Clinical Oncology 35thAnnual Meeting, atlanta (1999). Triggering a proliferative and delayed-type hypersensitivity (DTH) T cell response indicative of T-helper cell activity, but in fresh bloodNo cytolytic killer T cell activity was observed in the samples.
Additional examples of attempts to identify TuAAs for use as vaccines are seen in recent work by Cebon et al and Scheibenbogen et al. Cebon et al use MART-1 administered intradermally26-35Peptides and IL-12 administered subcutaneously or intravenously in increasing doses immunize patients with metastatic melanoma. Of the first 15 patients, 1 complete remission, 1 partial remission, and 1 mixed response were noted. Immunoassays for T cell production include DTH, which is found in patients with or without IL-12. Positive CTL assays were found in patients with evidence of clinical benefit (clinical benefit), but not in patients without tumor regression. Cebon et al, "Phase I students of Immunization with Melan-A and IL-12in HLA A2+ Positive Patients with Stage III and IV Malignant Melanoma," [ Abstract 1671],American Society of Clinical Oncology 35thAnnual Meeting, atlanta 1999).
Scheibenbergen et al immunized 18 patients with 4 HLA class I restricted tyrosinase peptides, 16 of which were immunized with metastatic melanoma and 2 with adjuvant. Scheibenbogen et al, "Vaccination with tyrosine peptides and GM-CSF in Metastatic Melanoma: a Phase II Trial, "[ abstract 1680],American Society of Clinical Oncology 35thAnnual Meeting, atlanta (1999). Enhanced CTL activity was observed in 4/15 patients, 2 of whom were immunized with adjuvant and 2 of whom had evidence of tumor regression. Patients with progressive disease (progressive disease) did not show enhanced immunity as in the Cebon et al trial. Despite the various efforts so far spent to produce effective anti-cancer vaccines, such compositions have not been developed.
Antiviral vaccine
Vaccine strategies to protect against viral diseases have met with much success. Perhaps the most significant of these has been the advancement made against the disease smallpox, which has been eradicated. The success of polio vaccines is of similar importance.
Viral vaccines can be divided into three categories: live attenuated virus vaccines, such as vaccinia for smallpox, sabin poliovirus vaccine, and measles mumps and rubella; completely killed or inactivated virus vaccines, such as the solvay poliovirus vaccine, the hepatitis a virus vaccine and the classical influenza virus vaccine; and subunit vaccines, such as hepatitis b. Due to their lack of a complete viral genome, subunit vaccines offer a greater degree of safety than those based on complete viruses.
An example of a successful subunit vaccine is a recombinant hepatitis b vaccine based on viral envelope proteins. Although many researchers are interested in pushing the concept of reduced speaker subunits beyond a single protein to individual epitopes, this effort has not produced much effort. Viral vaccine research has also focused on inducing antibody responses, although cellular responses also occur. However, many subunit preparations are particularly poor at generating CTL responses.
Summary of The Invention
Previous methods for eliciting the display of target cell epitopes by professional antigen presenting cells (pAPCs) have simply relied on making pAPCs express Target Associated Antigens (TAAs), or those epitopes that are believed to have high affinity for MHC class I molecules. However, proteasomal processing of such antigens results in epitopes presented on pAPC that do not correspond to epitopes on the target cell.
Using the knowledge that an effective cellular immune response requires pAPCs to present the same epitope presented by the target cell, the present invention provides epitopes with high affinity for MHC I and corresponding to the processing specificity of housekeeping proteasomes active in surrounding cells. These epitopes thus correspond to those presented on the target cells. The use of such epitopes in vaccines can activate cellular immune responses to recognize properly processed TAAs and can lead to the removal of target cells presenting such epitopes. In some embodiments, the housekeeping epitopes provided herein can be used in conjunction with immune epitopes to generate cellular immune responses that attack target cells both before and after interferon induction. In other embodiments the epitopes are used for diagnosis and monitoring of target-related diseases and for the production of immunological reagents for such purposes.

Detailed description of the preferred embodiments
Definition of
Unless otherwise clear from the context in which the terms herein are used, the terms listed below should generally have the indicated meanings for the purposes of this description.
Professional antigen presenting cells (papcs), cells that have a T cell costimulatory molecule and are capable of inducing a T cell response. Fully characterized pAPCs include dendritic cells, B cells and macrophages.
Surrounding cells-cells that are not pAPC.
Housekeeping proteasomes, proteasomes that are usually active in surrounding cells, are usually absent or not strongly active in pAPCs.
Immunoproteasome-the proteasome normally active in pAPCs; immunoproteasome is also active in some of the surrounding cells of infected tissue.
Epitope-a molecule or substance capable of stimulating an immune response. In a preferred embodiment, an epitope according to the present definition includes, but is not necessarily limited to, a polypeptide and a nucleic acid encoding a polypeptide, wherein the polypeptide is capable of stimulating an immune response. In other preferred embodiments, epitopes according to the present definition include, but are not necessarily limited to, peptides present on the cell surface that bind non-covalently to the MHC class I binding cleft so that they can interact with T cell receptors.
MHC epitope-a polypeptide having known or predicted binding affinity to a mammalian class I or class II Major Histocompatibility Complex (MHC) molecule.
Housekeeping epitope-in a preferred embodiment, a housekeeping epitope is defined as a polypeptide fragment, which is an MHC epitope, and which is displayed on cells in which the activity of the housekeeping proteasome is prominent. In another preferred embodiment, the housekeeping epitope is defined as a polypeptide comprising a housekeeping epitope according to the preceding definition, flanked by one to several additional amino acids. In another preferred embodiment, the housekeeping epitope is defined as a nucleic acid encoding a housekeeping epitope according to the preceding definition.
Immune epitope-in a preferred embodiment, an immune epitope is defined as a polypeptide fragment, which is an MHC epitope, and is displayed on cells in which housekeeping proteasome activity is prominent. In another preferred embodiment, an immune epitope is defined as a polypeptide comprising an immune epitope according to the previous definition flanked by one to several additional amino acids. In another preferred embodiment, an immune epitope is defined as a polypeptide comprising an epitope clustering sequence comprising at least two polypeptide sequences having known or predicted affinity for MHC class I. In yet another preferred embodiment, an immune epitope is defined as a nucleic acid encoding an immune epitope according to any one of the above definitions.
Target cells-cells targeted by vaccines and methods of the invention. Examples of target cells according to the present definition include, but are not necessarily limited to: neoplastic cells and cells containing intracellular parasites, such as viruses, bacteria or protozoa.
Target Associated Antigen (TAA) -a protein or polypeptide present in a target cell.
Tumor associated antigen (TuAA) — TAA, wherein the target cell is a neoplastic cell.
HLA epitope-a polypeptide having known or predicted binding affinity to a human HLA class I or class II complex molecule.
Antibody-polyclonal or monoclonal native immunoglobulin (Ig), or any molecule consisting wholly or partially of an Ig-binding domain, whether biochemically derived or obtained by using recombinant DNA. Examples include, inter alia, F (ab), single chain Fv and Ig variable region-phage coat protein fusions.
Encoding-an open-ended term such that a nucleic acid encoding a particular amino acid sequence may consist of codons specifying that (poly) peptide, but may also contain additional sequences that are translatable or that are used to control transcription, translation or replication, or that facilitate manipulation of the nucleic acid construct of some hosts.
Material similarity-this term is used to refer to sequences that differ from a reference sequence in an indirect manner, as determined by examination of the sequences. Nucleic acid sequences encoding the same amino acid sequence are substantially similar despite differences in degenerate positions or modest differences in length or composition of any non-coding region. Except that amino acid sequences which differ by conservative substitutions or small length changes are substantially similar. In addition, the amino acid sequences comprising housekeeping epitopes that differ in the number of flanking residues at the N-terminus, or immunological epitopes and epitope clusters that differ in the number of flanking residues at either terminus, are substantially similar. Nucleic acids that encode substantially similar amino acid sequences are themselves also substantially similar.
Functional similarity-the term is used to refer to sequences that differ from a reference sequence in an indirect manner, as determined by assaying for a biological or biochemical property, although the sequences may not be substantially similar. For example, two nucleic acids can be used as hybridization probes for the same sequence but encoding different amino acid sequences. Even if they differ by non-conservative amino acid substitutions (and therefore do not meet the definition of material similarity), the two peptides that induce a cross-reactive CTL response are functionally similar. Paired antibodies or TCRs recognizing the same epitope may be functionally similar to each other, although there are any structural differences. In testing for functional similarity in immunogenicity, individuals are typically immunized with an "altered" antigen and tested for the ability of the priming response (Ab, CTL, cytokine production, etc.) to recognize the target antigen. Thus, two sequences can be designed that differ in some way while retaining the same function. Such designed sequence variants are in embodiments of the invention.

All accession numbers used here and throughout may be accessed through the NCBI database, for example through the Entrez search and retrieval system on the world wide web.
Note that the following discussion sets forth an understanding of the inventors' operation of the present invention. However, the discussion is not intended to limit the patent to any particular theory of operation not set forth in the claims below.
In the development of epitope vaccines, others have generated a list of predicted epitopes based on MHC binding motifs. Such peptides may be immunogenic, but may not correspond to any naturally occurring antigenic fragment. Thus, the whole antigen will not elicit a similar response or sensitize the target cells to cytolysis by CTLs. This list therefore does not distinguish between those sequences that can be used as vaccines and those that cannot. Efforts to determine which of these predicted epitopes are actually naturally occurring have often relied on screening for their reactivity with Tumor Infiltrating Lymphocytes (TILs). However, although tumors (and chronically infected cells) will typically present housekeeping epitopes, TIL strongly favors the recognition of immune epitopes. Thus, unless the epitope is produced by both housekeeping and immunoproteasome, the target cell will not normally be recognized by CTLs induced with TIL-identified epitopes. In contrast, the epitopes of the present invention are produced by the action of specific proteasomes, suggesting that they can be produced naturally and given their appropriate utility. The significance of the differences between housekeeping and immune epitopes for vaccine design is more fully elucidated in PCT publication WO 01/82963a 2.
The epitopes of the invention include or encode polypeptide fragments of TAAs, which are precursors or products of proteasomal cleavage by housekeeping or immunoproteasome, and contain or include sequences having known or predicted affinity for at least one MHC I allele. In some embodiments, the epitope comprises or encodes a polypeptide of about 6 to 25 amino acids in length, preferably about 7 to 20 amino acids in length, more preferably about 8 to 15 amino acids in length, and still more preferably about 9 or 10 amino acids in length. However, it will be appreciated that the polypeptides may be larger as long as the N-terminal trim can generate MHC epitopes or they do not contain sequences that cause the polypeptide to be directed away from or destroyed by the proteasome. For immune epitopes, larger peptides can be processed in pAPC for immunoproteasome if they do not contain such sequences. Housekeeping epitopes may also be embedded in longer sequences if the sequence is adapted to promote release of the C-terminus of the epitope by immunoproteasome action. The above discussion has assumed that processing of longer epitopes is performed by the action of the pAPC immunoproteasome. However, processing can also be accomplished by designing some other mechanism, such as the release of MHC epitopes by the action of proteases, which provides exogenous protease activity and adapted sequences. These epitope sequences can be subjected to computer analysis to calculate physical, biochemical, immunological or molecular genetic properties, such as mass, isoelectric point, predicted electrophoretic mobility, predicted binding to other MHC molecules, melting temperature of nucleic acid probes, reverse translation, similarity or homology to other sequences, etc.
In the construction of a polypeptide encoding the present inventionIn the polynucleotide of the epitope, the gene sequence of the relevant TAA may be used, or the polynucleotide may be assembled from any corresponding codons. For an epitope of 10 amino acids, this may constitute about 106And (ii) different sequences, depending on the particular amino acid composition. Although large, this is a distinct and easily defined set, which represents > 1018This length may be a small percentage of the possible polynucleotides, and thus in some embodiments, equivalents to the specific sequences disclosed herein include such divergent and readily definable variations on the listed sequences. In selecting a particular one of these sequences for use in a vaccine, conditions such as codon usage, self-complementarity, restriction sites, chemical stability, etc., may be utilized as will be apparent to those skilled in the art.
The present invention is intended to produce peptide epitopes. In particular, these epitopes are derived from the TAA sequence and have a known or predicted affinity for at least one MHC I allele. Such epitopes are typically identical to those produced on target cells or pAPCs.
Compositions comprising active epitopes
Embodiments of the invention provide polypeptide compositions, including vaccines, therapeutics, diagnostics, pharmacology and pharmaceutical compositions. Various compositions include newly identified epitopes of TAAs as well as variants of these epitopes. Other embodiments of the invention provide polynucleotides encoding epitopes of the polypeptides of the invention. The invention further provides vectors for expressing polypeptide epitopes suitable for purification. In addition, the present invention provides a vector for expressing a polypeptide epitope in APC for use as an anti-tumor vaccine. Any epitope or antigen derived from table 1, or nucleic acid encoding it, may be used. Other embodiments relate to methods of making and using the various compositions.
The overall structure of MHC class I-binding epitopes can be described in Madden, d.r.annu.rev.immunol.13: 587 and 622, 1995. Many of the binding events can arise from the backbone linkage between conserved residues in MHC molecules and the N-and C-termini of peptidesAnd (4) contacting. Additional backbone contacts were generated but were different in the MHC alleles. Sequence specificity is conferred by the side chain of the so-called anchor residue in contact with a pocket that in turn varies in the MHC allele. Anchor residues can be divided into primary (primary) and secondary (secondary). The primary anchor positions show a strongly preferred set of relatively well-defined amino acid residues. Minor sites show weaker and/or less strictly defined preferred residues, which can often be better described in terms of less preferred than more preferred. In addition, residues in some minor anchor sites are not always located in contact with pockets on MHC molecules at all. Thus, there is one subtype of peptide that binds to a particular MHC molecule and presents a side-pocket contact at the site in question, and another subtype that exhibits binding to the same MHC molecule independent of the conformation the peptide presents in the MHC molecule peptide-binding groove. The C-terminal residue (P; ω) is preferably the primary anchor residue. The second position (P2) is also an anchor residue for many of the better studied HLA molecules (e.g. a2, a68, B27, B7, B35 and B53). However, central anchor residues have also been observed, including P3 and P5 in HLA-B8, and H-2D, respectively, in the murine MHC moleculebAnd H-2KbP5 and P (ω) -3 in (1). Because more stable binding will generally improve immunogenicity, regardless of their position, it is preferred that the anchor residues be conserved or optimized in designing variants.
Since the anchor residue is usually located near the end of the epitope, the peptide bends upward out of the peptide-binding groove, which allows some variation in length. Epitopes of 8-11 amino acids have been found for HLA-A68, and up to 13 amino acids for HLA A2. In addition to the length change between anchor positions, single residue truncation and extension and at the N-and C-termini, respectively, have been reported. Among the non-anchor residues, some protrude outside the groove, do not come into contact with MHC molecules but can be used to contact the TCR, most often P1, P4 and P (ω) -1 for HLA-a2. Other non-anchor residues may become inserted between the upper edge of the peptide binding groove and the TCR, contacting both. The precise location of these side chain residues, and thus their effect on binding, MHC fine conformation and ultimately immunogenicity, is highly sequence dependent. For highly immunogenic epitopes, it must not only promote sufficient TCR binding that is stable for activation to occur, but the TCR must also have a sufficiently high off-rate so that multiple TCR molecules can interact sequentially with the same peptide-MHC complex (Kalergis, A.M. et al, Nature Immunol.2: 229-234, 2001). Thus, without additional information about the ternary complex, both conservative and non-conservative substitutions at these positions are worth considering when designing variants.
Polypeptide epitope variants can be generated, for example, using any of the techniques and guidelines for conservative and non-conservative mutations. Variants may be derived from substitution, deletion or insertion of one or more amino acids compared to the native sequence. An amino acid substitution can be the result of substituting one amino acid with another having similar structural and/or chemical properties, such as substituting threonine with serine. Such substitutions are referred to as conservative amino acid substitutions, and all suitable conservative amino acid substitutions are considered an embodiment of the invention. Insertions or deletions can optionally be of about 1 to 4, preferably 1 to 2, amino acids. It is generally preferred to maintain an "anchor site" for the peptide, which is responsible for binding to the MHC molecule in question. Indeed, in many cases the immunogenicity of peptides can be improved by replacing more preferred residues at the anchor site (Franco, et al, Nature Immunology, 1 (2): 145-150, 2000). The immunogenicity of peptides can often also be improved by substituting small amino acids found at non-anchoring sites with larger volumes of amino acids, while maintaining sufficient cross-reactivity with the original epitope to constitute an effective vaccine. The allowable variation can be determined by conventional insertion, deletion or substitution of amino acids in the sequence and examination of the resulting variants for the activity exhibited by the polypeptide epitope. Since polypeptide epitopes are often 9 amino acids, it is preferred to replace the shortest active epitope, for example an epitope of 9 amino acids.
Variants can also be generated by adding any sequence to the N-terminus of the polypeptide epitope variant. Such an N-terminal increase may be from 1 amino acid up to at least 25 amino acids. Since peptide epitopes are often trimmed by the active N-terminal exopeptidase in pAPC, it must be understood that variations in the added sequence may have no effect on epitope activity. In a preferred embodiment, the amino acid residue between the last upstream proteasome cleavage site and the N-terminus of the MHC epitope does not include a proline residue. Serwold, t, et al, Nature immunol.2: 644-651, 2001. Thus, effective epitopes can be generated from larger precursors than the preferred 9-mer class I motif.
Generally, peptides are effective in the sense that they correspond to the epitope actually displayed by MHC I on the surface of the target cell or pACP. Individual peptides may have different affinities for different MHC molecules, binding well to some, and not binding at all (table 2). MHC alleles have traditionally been classified according to serological reactivity, which does not reflect the structure of peptide-binding grooves that may differ in the same type of allele. Similarly, cross type (across type) may share binding properties; the class group based on the shared binding property has been called supertype. There are many MHC I alleles in the human population; epitopes specific for certain alleles can be selected based on the genotype of the patient.

In further embodiments of the invention, the epitope, either as a peptide or encoding polynucleotide, may be administered as a pharmaceutical composition, e.g., a vaccine or immunogenic composition, alone or in combination with various adjuvants, carriers or excipients. It should be noted that although the term vaccine may be used throughout the discussion herein, this concept may be administered or used with any other pharmaceutical composition including those mentioned herein. Particularly advantageous adjuvants include various cytokines and oligonucleotides comprising immunostimulatory sequences (as set forth in more detail in the co-pending applications referenced herein). Alternatively, the polynucleotide encoding the epitope may be contained in a virus (e.g., vaccinia or adenovirus) or in a microbial host cell (e.g., Salmonella (Salmonella) or Listeria monocytogenes), which is then used as a vector for the polynucleotide (Dietrrich, G. et al nat. Biotech.16: 181-185, 1998). Alternatively, pAPC can be transformed ex vivo to express the epitope, or pulsed with a peptide epitope to administer itself as a vaccine. To improve the efficiency of these methods, viral or bacterial vectors can be used to carry the encoded epitope or complexed with a ligand for the receptor found on pAPC. Similarly, the peptide epitope can be complexed or conjugated to a pAPC ligand. A vaccine may comprise more than one single epitope.
A particularly advantageous strategy for incorporating EPITOPEs and/or clusters of EPITOPEs into a vaccine or pharmaceutical composition is disclosed in U.S. patent application No. 09/560,465 filed on year 2000, month 4, 28, entitled "EPITOPE SYNCHRONIZATION IN ANTIGEN PRESENTING CELLS". EPITOPE clustering for use with the present invention is disclosed in U.S. patent application No.09/561,571 entitled "EPITOPE CLUSTERS" filed at 28/4 in 2000.
Preferred embodiments of the invention are directed to vaccines and methods that allow the pAPC or pAPCs population to present housekeeping epitopes corresponding to the epitopes displayed on a particular target cell. For example, any epitope or antigen from table 1 can be used. In one embodiment, the housekeeping epitope is a TuAA epitope processed by the housekeeping proteasome of a particular tumor type. In another embodiment, the housekeeping epitope is a virus-associated epitope processed by the housekeeping proteasome of a cell infected with the virus. This promotes a specific T cell response to the target cells. Because they display housekeeping or immune epitopes, simultaneous expression of multiple epitopes corresponding to different induction states (pre-or post-challenge) of pAPCs can elicit CTL responses effective against target cells.
This embodiment can optimize the cytotoxic T cell response to target cells by containing housekeeping and immune epitopes presented on pAPC. Through dual epitope expression, pAPCs can continue to maintain CTL responses to immune-type epitopes when tumor cells are switched from housekeeping proteasomes to immunoproteasomes under induction by IFNs, which can be produced, for example, by tumor infiltrating CTLs.
In a preferred embodiment, the patient is immunized with a vaccine comprising a housekeeping epitope. Many preferred TAAs are specifically associated with a target cell, particularly in the case of infected cells. In another embodiment, many preferred TAAs are the result of deregulated (deregulated) gene expression in transformed cells, but are also found in testis, ovarian tissue and fetuses. In another embodiment, effective TAAs are expressed at higher levels in target cells than in other cells. In other embodiments, TAAs are not differentially expressed in target cells compared to other cells, but are also effective because they are associated with one particular function of the cell and distinguish the target cell from most other surrounding cells; in these embodiments, it was also shown that healthy cells of TAAs may be attacked in parallel by the induced T cell response, but this collateral damage is considered to be far more preferable than what the target cells cause.
The vaccine comprises a housekeeping epitope in an effective concentration that results in a population of pAPCs or pAPCs displaying the housekeeping epitope. Advantageously, the vaccine may comprise a plurality of housekeeping epitopes or one or more housekeeping epitopes optionally in combination with one or more immunological epitopes. The vaccine formulation comprises peptides and/or nucleic acids at a concentration sufficient to cause epitope presentation by pAPCs. The formulation preferably contains the epitope at a total concentration of about 1. mu.g to 1mg per 100. mu.l of vaccine formulation. The present invention may employ conventional dosages and dosages suitable for peptide vaccines and/or nucleic acid vaccines, the method of administration being well understood in the art. In one embodiment, a single dose for an adult may conveniently be from about 1 μ l to about 5000 μ l of the composition, administered one or more times, for example 2, 3, 4 or more doses spaced 1 week, 2 weeks, one month or more apart. Refer to the intra-nodal method patent insulin pump (insulin pump) delivers 1 μ l per hour (lowest frequency).
The compositions and methods of the invention disclosed herein are also intended to incorporate adjuvants into the formulations to enhance the performance of the vaccines. Specifically, adjuvants are designed to be added to the formulation to enhance epitope delivery or uptake of pAPCs. Adjuvants contemplated by the present invention are known to those skilled in the art and include, for example, GMCSF, GCSF, IL-2, IL-12, BCG, tetanus toxin, osteopontin, and ETA-1.
In some embodiments of the invention, the vaccine may comprise a recombinant organism, such as a virus, bacterium or parasite genetically engineered to express an epitope in a host. For example, listeria monocytogenes, a gram-positive, facultative intracellular bacterium, is an effective vehicle for targeting TuAAs to the immune system. In a preferred embodiment, the vector can be engineered to express a housekeeping epitope to induce a therapeutic response. The normal route of infection for this organism is through the intestine and can be delivered orally. In another embodiment, an adenovirus (Ad) vector encoding a housekeeping epitope against TuAA can be used to induce an antiviral or antitumor response. Dendritic cells derived from bone marrow can be transduced with the viral construct and subsequently injected, or the virus can be delivered directly into the animal by subcutaneous injection to induce an effective T-cell response. Another embodiment uses a recombinant vaccinia virus engineered to encode an amino acid sequence corresponding to a housekeeping epitope against TAA. Vaccinia virus carrying constructs containing appropriate nucleotide substitutions in the form of minigene constructs can direct the expression of housekeeping epitopes, resulting in therapeutic T cell responses against the epitopes.
Immunization with DNA requires APCs to take up the DNA and express the encoded protein or peptide. Discrete class I peptides may be encoded on DNA. By immunization with this construct, APCs can be made to express housekeeping epitopes, which are then displayed on cell surface MHC class I to stimulate an appropriate CTL response. A construct that generally relies on translational termination or non-proteasomal proteases to generate appropriate housekeeping epitope termini has been described in U.S. patent application No.09/561,572 filed on year 2000, month 4, 28, entitled EXPRESSION VECTORS OF Target-As recognized antibodies.
As mentioned, it is desirable to express the housekeeping peptide in a larger protein context. Processing can be detected even when a small amount of amino acids are present beyond the epitope end. Small peptide hormones are usually proteolytically processed from longer translation products, often about 60-120 amino acids in size. This fact has led some to assume that this is the smallest size that can be translated efficiently. In some embodiments, the housekeeping peptide may be embedded in the translation product of at least about 60 amino acids. In other embodiments the housekeeping peptide may be embedded in the translation product of at least about 50, 30 or 15 amino acids.
Due to differential proteasomal processing, the immunoproteasome of pAPC produces different peptides than those produced by housekeeping proteasomes in surrounding somatic cells. Thus, in expressing the housekeeping peptide in the context of a larger protein, it is preferred to express it in the APC in a context different from its full-length native sequence, since, as a housekeeping epitope, it is usually only efficiently processed from the native protein by the housekeeping proteasome, which is not active in the APC. To encode the housekeeping epitope in a DNA sequence encoding a larger protein, it is useful to find flanking regions on either side of the sequence encoding the epitope that allow for appropriate cleavage by the immunoproteasome to release the housekeeping epitope. Altering the flanking amino acid residues at the N-and C-termini of the desired housekeeping epitope can facilitate proper cleavage and production of the housekeeping epitope in the APC. Sequences of the embedded housekeeping epitopes can be newly designed and screened to determine which can be successfully processed by the immunoproteasome to release the housekeeping epitope.
Alternatively, another strategy is very effective for identifying sequences that allow the generation of housekeeping epitopes in APCs. A contiguous amino acid sequence can result from the head-to-tail arrangement of one or more housekeeping epitopes. An animal is immunized with a construct expressing the sequence and the resulting T cell response is evaluated to determine its specificity for one or more epitopes in the array. By definition, these immune responses show housekeeping epitopes that are efficiently processed in pAPC. The necessary flanking regions around the epitope are thus determined. The use of flanking regions of about 4-6 amino acids on either side of the desired peptide may provide the information necessary to facilitate proteasomal processing of housekeeping epitopes by immunoproteasome. Thus, a sequence of about 16-22 amino acids that ensures epitope synchronization can be efficiently inserted or fused to any protein sequence to result in the production of housekeeping epitopes in APCs. In alternative embodiments, the entire head-to-tail arrangement of epitopes, or just the epitopes immediately adjacent to the correctly processed housekeeping epitope, can be similarly transferred from the test construct to the vaccine vector.
In a preferred embodiment, housekeeping epitopes may be embedded within known immune epitopes, or between such segments, to provide a context suitable for processing. The juncture of the housekeeping and immunizing epitopes may generate the necessary context for the immunoproteasome to release the housekeeping epitope, or a larger fragment preferably comprising the correct C-terminus. Screening of the construct to confirm production of the desired epitope is useful. Binding sites for housekeeping epitopes may create sites that can be cleaved by immunoproteasome. Some embodiments of the invention use known epitopes to flank a housekeeping epitope in a test substrate; in other embodiments, the screening described below is used to determine whether the flanking regions are any sequence or a mutant of the native flanking sequence, using knowledge of the preference for proteasome cleavage in designing the substrate.
Although advantageous, cleavage at the N-terminus of the mature epitope is not necessary because there are a variety of N-terminal trimming activities in the cell that are capable of producing the mature epitope N-terminus after proteasome processing. Preferably, the N-terminal extension is less than about 25 amino acids in length, and further preferably the extension contains little or no proline residues. Preferably, in the screening, consideration is given not only to cleavage at the end of the epitope (or at least at its C-terminus), but also to ensuring limited cleavage within the epitope.
The shotgun method can be used to design test substrates and can improve screening efficiency. In one embodiment, multiple epitopes can be combined in sequence, and a single epitope can appear multiple times. The substrate can be screened to determine which epitopes can be produced. In cases where a particular epitope is of interest, one can design a substrate in which it occurs in a variety of different context sequences. When a single epitope present in more than one pre-and post-sequence is released from the substrate, an additional second test substrate in which a particular instance (antigenic entities) of the epitope is removed, disabled or unique can be used to determine which is the sequence that is released and indeed constitutes the sequence that ensures epitope simultaneity.
There are several easily practiced screens. One preferred in vitro screen utilizes a proteasome digestion assay that uses purified immunoproteasome to determine whether the desired housekeeping epitope can be released from a synthetic peptide comprising the sequence in question. The position at which cleavage is obtained can be determined by techniques such as mass spectrometry, HPLC and N-terminal pool sequencing; as described in more detail in U.S. patent application entitled METHOD OF EPITOPE DISCOVERY, EPITOPE SYNCHRONIZATION IN ANTIGENPRESENTING CELLS, two provisional U.S. patent applications entitled EPITOPE SEQUENCES.
Alternatively, in vivo screening such as immunization or target sensitization may be used. For immunization nucleic acid constructs are used which can express the sequence in question. The ability of the harvested CTLs to recognize target cells presenting the housekeeping epitope in question can be examined. Such target cells are extremely easy to obtain by pulsing cells expressing appropriate MHC molecules with synthetic peptides containing mature housekeeping epitopes. Alternatively, cells and antigens known to express housekeeping proteasomes can be used, from which housekeeping epitopes can be derived endogenously or by genetic engineering. For the purpose of using target sensitization as a sieve, CTLs recognizing housekeeping epitopes, or preferably CTL clones, can be used. In this case, it is the target cell expressing the embedded housekeeping epitope (rather than pAPC during immunization) and it must express the immunoproteasome. In general, a target cell can be transformed with an appropriate nucleic acid construct to confer expression of an embedded housekeeping epitope. Using peptide-loaded liposomes or protein transfer agents such as BIOPORTERTM(Gene Therapy Systems, San Diego, Calif.) Loading a synthetic peptide containing an embedded epitope represents an alternative.
Additional guidance regarding nucleic acid constructs for use AS vaccines according to the present invention is disclosed in U.S. patent application No.09/561,572 entitled "EXPRESSION VECTORS OF TARGET-AS contacted antibodies", filed on 28.4.2000. In addition, EXPRESSION VECTORS useful in accordance with the present invention and METHODS FOR their design are disclosed in U.S. patent application No. 60/336,968 (attorney docket number) CTLIMM.022PR entitled "EXPRESSION VECTORS OF TARGET-ASSOCIATED ANTIGENS AND METHODS FOR THEIR DESIGN", filed at 11/7/2001.
A preferred embodiment of the invention comprises a method of administering a vaccine comprising an epitope (or epitopes) to induce a therapeutic immune response. The vaccine is administered to the patient in a manner consistent with standard vaccine delivery protocols known in the art. Methods of administering TAAs epitopes include, but are not limited to, transdermal, intranodal, perinodal, oral, intravenous, intradermal, intramuscular, intraperitoneal and mucosal administration, including delivery by injection, instillation or inhalation. Australian patent No. 739189 issued on 17.1.2002; U.S. patent application No. 09/380,534, filed 9/1/1999, entitled "A METHOD OF INDUCING A CTL RESPONSE"; and its continuation-in-part application, U.S. patent application No. 09/776,232 filed on 2/2001, disclose a particularly useful method of delivering a vaccine to elicit a CTL response.
Reagent recognition epitopes
In another aspect of the invention, proteins having binding specificity for an epitope and/or epitope-MHC molecule complex are contemplated, as well as isolated cells by which they may be expressed. In one set of embodiments, these agents take the form of immunoglobulins: polyclonal sera or monoclonal antibodies (mabs), methods for producing which are well known in the art. The generation of mabs specific for peptide-MHC molecule complexes is known in the art. See, e.g., aharoi et al, Nature 351: 147, 150, 1991; andersen et al proc.natl.acad.sci.usa 93: 1820-1824, 1996; dadaglio et al Immunity 6: 727 738, 1997; duc et al int. Immunol.5: 427 gradient 431, 1993; eastman et al eur.j.immunol.26: 385-393, 1996; engberg et al Immunotechnology 4: 273-278, 1999; porgdor et al Immunity 6: 715-726, 1997; puri et al j.immunol.158: 2471-2476, 1997; and Polakova, k., et al, j.immunol.165342-348, 2000.
In other embodiments, the compositions can be used to induce and generate T-cells specific for any epitope and/or epitope-MHC complex in vivo and in vitro. In a preferred embodiment, the epitope may be any one or more of those listed, for example, in table 1. Thus, embodiments also relate to and include isolated T cells, T cell clones, T cell hybridomas or proteins comprising a T Cell Receptor (TCR) binding domain derived from a cloned gene, and recombinant cells expressing the proteins. The TCR-derived protein may be the extracellular domain of a TCR alone, or fused to a portion of another protein to confer a desired property or function. One example of such a fusion is the attachment of a TCR binding domain to a constant region of an antibody molecule in order to produce a bivalent molecule. The construction and activity of molecules according to this general model has been reported, for example Plaksin, d. et al j.immunol.158: 2218-2227, 1997 and Lebowitz, M.S. et al Cell Immunol.192: 175-184, 1999. More general construction AND USE of such molecules is also discussed IN U.S. patent 5,830,755 entitled CELL RECEPTORS AND THEIR USE IN thermal AND DIAGNOSTIC METHODS.
The production of such T cells can be readily achieved by standard immunization of laboratory animals and reactivity to human target cells can be obtained by immunization with human target cells or by immunization of HLA-transgenic animals with antigens/epitopes. For some therapeutic approaches, T cells derived from the same species are desirable. Although this cell can be generated by, for example, cloning a murine TCR into a human T cell as contemplated above, in vitro immunization of human cells offers a potentially faster selection. Even with donors used for the first time in experiments (naive donors), techniques for in vitro immunization are known in the art, e.g. Stauss et al, proc.natl.acad.sci.usa 89: 7871-7875, 1992; salgaleler et al Cancer Res.55: 4972-4979, 1995; tsai et al, j.immunol.158: 1796-; and Chung et al, J immunoher.22: 279-287, 1999.
Any of these molecules can be coupled to enzymes, radiochemical reagents, fluorescent tags and toxins for use in diagnosis (imaging or other detection), monitoring and treatment of epitope-related pathogenic diseases. Thus, toxin conjugates can be administered to kill tumor cells, radiochemical reagents can facilitate imaging of epitope positive tumors, enzyme conjugates can be used in assays like ELISA to diagnose cancer and confirm epitope expression in biopsy tissues. In another embodiment, such T cells as set forth above may be administered to a patient as an adoptive immunotherapy after expansion is completed by stimulation with epitopes and/or cytokines.
Agents comprising epitopes
Another aspect of the invention provides isolated epitope-MHC complexes. In particularly advantageous embodiments of this aspect of the invention, the complex may be a soluble, multi-subunit protein such as those described in U.S. Pat. No.5,635,363 (tetramer) or U.S. Pat. No.6,015,884 (Ig-dimer). The reagents are useful for detecting and monitoring specific T cell responses, and for purifying such T cells.
Isolated MHC molecules complexed with epitope peptides can also be incorporated into planar lipid bilayers or liposomes. Such compositions can be used to stimulate T cells in vitro or, in the case of liposomes, in vivo. Costimulatory molecules (e.g., B7, CD40, LFA-3) can be incorporated into the same composition, or, particularly for in vitro manipulation, costimulation can be provided by anti-co-receptor antibodies (e.g., anti-CD 28, anti-CD 154, anti-CD 2) or cytokines (e.g., IL-2, IL-12). Such T cell stimulation may constitute vaccination in immunotherapy, driving T cell expansion in vitro for subsequent fusion, or constitute a step in an assay for T cell function.
The epitope, or more directly its complex with an MHC molecule, may be an important component of a functional assay of antigen-specific T cells in the activation or readout step or both. Two broad classes can be defined in the Current art for a wide variety of assays for T cell function (detailed methods can be found in standard immunological references such as Current Protocols in Immunology 1999 John Wiley & Sons inc., n.y), those measuring many cellular responses and those measuring individual cellular responses. While the former conveys an overall measure of the intensity of the response, the latter allows the relative frequency of responding cells to be determined. Examples of assays that measure overall response are cytotoxicity assays, ELISA and proliferation assays that detect cytokine secretion. Assays FOR measuring individual cell (or miniclone derived therefrom) responses include Limiting Dilution Analysis (LDA), ELISPOT, flow cytometry detection OF non-secreted cytokines (in U.S. patent No.5,445,939 entitled "METHOD FOR assay OF THE same monomer empty monomer SYSTEM" and U.S. patent No.5,656,446 entitled "METHOD FOR THE ASSESSMENT OF THE same monomer empty monomer SYSTEM"; and 5,843,689, reagents are sold under the trade name 'FASTIMMENE' by Becton, Dickinson & Company and the relative advantages of these techniques are reviewed in Current Opinion in Immunology, 13: 141-, in particular in situ and single cell PCR techniques, may accomplish additional rearrangements or expression of the detected specific TCR.
These functional assays can be used to assess endogenous levels of immunity, response to immune stimuli (e.g., vaccines) and to monitor immune status throughout disease and treatment periods. Any of these assays presumes a prior immunization step, whether in vivo or in vitro, which depends on the nature of the problem in question, except when measuring endogenous levels of immunity. The immunization can be performed using various embodiments of the invention described above or other forms of immunogens (e.g., pAPC-tumor cell fusions) that can elicit similar immunity. In addition to PCR and tetramer/Ig-dimer type assays capable of detecting expression of the cognate tcr (cognate tcr), these assays generally benefit from one-step in vitro antigen stimulation, which can conveniently use the various embodiments of the invention described above in order to detect specific functional activities (and sometimes a highly cytolytic response directly). Finally, detection of cytolytic activity requires target cells displaying epitopes, which can be generated using various embodiments of the present invention. The particular embodiment chosen for any particular step depends on the issues discussed, ease of use, cost, etc., but the advantages of one embodiment over another for any particular set of circumstances will be apparent to one skilled in the art.
Peptide MHC complexes described in this section have traditionally been understood to be non-covalent binding. However, it is possible and may be beneficial to create a covalent bond, for example by encoding the epitope as a single protein and an MHC heavy chain or epitope, β 2-microglobulin, and MHC heavy chain (Yu, Y.L.Y., et al, J.Immunol.168: 3145-opsin 3149, 2002; Mottez, E., et al, J.exp.Med.181: 493, 1995; Dela Cruz, C.S., et al, int.Immunol.12: 1293, 2000; Mage, M.G., 369, et al, Proc.Natl.Acad.Sci.USA 89: 10658, 1992; Toshitani, K., et al, Proc.Natl.Acad.Sci.USA 93: 236, 1996; Lee, L.L, et al, Eur.J.24: 2633, Chung, Whd.H., J.J.163.J.J.J.USA 93: 236, 1996; 1999, J.J.162, 1999, J.162, 1999, J.J.162, 1999, J.A.162, J.162, J.A.162, 1999, et al, and similar approaches have been described for the vaccine, and for the analogous approach to overcome the difficulties in the A.A.A.A.7, J.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A..
Tumor associated antigens
The epitopes of the invention are derived from TuAAs tyrosinase (SEQ ID NO.2), SSX-2, (SEQ ID NO.3), PSMA (prostate-specific membrane antigen) (SEQ ID NO.4), GP100, (SEQ ID NO.70), MAGE-1, (SEQ ID NO.71), MAGE-2, (SEQ ID NO.72), MAGE-3, (SEQ ID NO.73), NY-ESO-1, (SEQ ID NO.74), PRAME, (SEQ ID NO.77), PSA, (SEQ ID NO.78), PSCA, (SEQ ID NO.79), fibronectin ED-B domain (SEQ ID NOS 589 and 590), CEA (carcinoembryonic antigen) (SEQ ID NO.592), Her2/Neu (SEQ ID NO.594), SCP-1(SEQ ID NO.596) and SSX-4(SEQ ID NO. 598). The native coding sequence of these eleven proteins, or any segment within them, can be determined from their cDNA or complete coding (cds) sequences, SEQ ID NOS.5-7, 80-87, 591, 593, 595, 597, and 599, respectively.
Tyrosinase is a melanin biosynthetic enzyme that is considered to be one of the most specific markers of melanocyte differentiation. Tyrosinase is expressed in a few cell types, mainly in melanocytes, and is often found at high levels in melanomas. TYROSINASE is taught FOR use as TuAA in U.S. Pat. No.5,747,271 entitled "METHOD FOR IDENTIFYING INDIVIDUALS SUFFERING FROM A CELLULAR ABNORMALITY SOME OF WHOSE ABNORMAL CELLS PRESENT COMPLEXES OF HLA-A2/TYROSINE DERIVED PEPTIDES, ANDMETHODS FOR TREATING SAID INDIVIDUALS".
GP100, also known as PMe117, is also a melanin biosynthetic protein that is expressed at high levels in melanoma. GP100, a TuAA, is disclosed IN U.S. Pat. No.5,844,075 entitled "MELANOMAANTIGENS AND THEIR USE IN DIAGNOSTIC AND THERAPEUTIC METHODS".
SSX-2, also known as Hom-Mel-40, is a member of the highly conserved cancer-testis antigen family (Gure, A.O. et al int.J.cancer 72: 965-971, 1997). The identification as a TuAA is taught in U.S. Pat. No.6,025,191 entitled "ISOLATED NUCLEIC ACID MOLECULES A MELANOMA SPECIFIC ANTIGEN AND USES THEREOF". Cancer-testis antigens are found in a variety of tumors, but are not normally found in normal adult tissues other than the testis. It has been found that different members of the SSX family are expressed differently in tumor cell lines. Because of the high degree of sequence identity between SSX family members, similar epitopes from more than one family member will be produced and can bind to MHC molecules, some vaccines directed to one member of the family can cross-react and be effective against other members of the family (see example 3 below).
MAGE-1, MAGE-2, and MAGE-3 are members of another cancer-testis antigen family that was originally found in melanoma (MAGE is an abbreviation for melanoma-associated antigen) but is found in many tumors. THE identification of MAGE proteins as TuAAs is taught in U.S. Pat. No.5,342,774 and many later patents entitled NUCLEOTIDE SEQUENCE ENCODING THE TUMOR REJECTION ANTIGEN PRECURSOR, MAGE-1. Currently there are 17 records on (human) MAGE in the SWISS protein database. There is extensive similarity among these proteins and thus in many cases epitopes derived from one can induce cross-reactive responses against other family members. Some of these have not been observed in tumors, most notably MAGE-H1 and MAGE-D1, which are expressed in testis and brain, and bone marrow stromal cells, respectively. The possibility of cross-reactivity on normal tissues is improved by the fact that they are among the least similar to other MAGE proteins.
NY-ESO-1, a cancer-testis antigen found in a variety of tumors, is also known as CTAG-1 (cancer-testis antigen-1) and CAG-3 (cancer antigen-3). NY-ESO-1, a TuAA, is disclosed in U.S. Pat. No.5,804,381 entitled Integrated Nuclear ACID Motor engineering AN agricultural chemical ISOLATED plant, THE same ISOLATED plant ITSELF, AND THE United states plant, to TuAA. Paralogous loci (paralogous loci), LAGE-1a/s (SEQ ID NO.75) and LAGE-1b/L (SEQ ID NO.76) encoding antigens with extensive sequence identity have been disclosed in publicly available human genome clusters (associations) and have been deduced to be produced by alternative splicing (alternative splicing). In addition, CT-2 (or CTAG-2, cancer-testis antigen-2) appears to be an allele, mutant or sequencing difference of LAGE-1 b/L. Due to the extensive sequence identity, many epitopes derived from NY-ESO-1 can also induce immunity against tumors expressing these other antigens. See fig. 1. The protein is virtually identical up to amino acid 70. The longest length of identity between 71-134NY-ESO-1 and LAGE is 6 residues, but potentially cross-reactive sequences are present. From 135-180, the NY-ESO and LAGE-1a/s are identical except for a single residue, but are not related due to alternative splicing of LAGE-1 b/L. CAMEL and LAGE-2 antigens appear to be derived from LAGE-1mRNA, but from variable reading frames, thus generating unrelated protein sequences. More recently, GenBank accession No. AF277315.5, human chromosome X clone RP5-865E18, RP5-1087L19, complete sequence, reported three separate loci in this region, labeled lag 1 (corresponding to CTAG-2 of the genomic cluster), plus lag 2-a and lag 2-B (both corresponding to CTAG-1 of the genomic cluster).
PSMA (PROSTATE specific membrane ANTIGEN), a TuAA described in U.S. Pat. No.5,538,866 entitled "PROSTATE-SPECIFICAMEMBRANE ES ANTIGEN", is expressed by normal PROSTATE epithelial cells and at high levels in PROSTATE cancer. It has also been found to be present in neovasculature of non-prostate tumors. PSMA may thus form the basis of a vaccine directed to both the neovasculature of prostate cancer and other tumors. This latter concept is more fully described in provisional U.S. patent application No. 60/274,063 entitled "ANTI-neovasular vehicles FOR cam" filed on 3/7/2001 and U.S. application No. 10/094,699 entitled "ANTI-neovasular devices FOR cam" filed on 3/7/2002, attorney docket No. ctllimm.015 a. Briefly, as tumors grow, they take up (regrait) an ingrowth of new blood vessels (ingowth). This is thought to be necessary for maintenance of growth, as the non-vascularized tumor centers usually necrose and angiogenesis inhibitors have been reported to cause tumor regression. These new blood vessels, or neovasculature, express antigens not found in the established blood vessels and can therefore be specifically targeted. By inducing CTLs against neovascular antigens, blood vessels can be disrupted, interrupting nutrient flow to (and removing waste products from) the tumor, leading to regression.
Alternative splicing of PSMAmRNA also results in a single event at Met 5,935,818, as described in U.S. Pat. No.3,3926 entitled "ISOLATED NUCLEIC ACID Motor ENCODING ALTERNATIVELY SPLICED State-SPECIFIC polynucleotides ANTIGEN AND USES THEREOF58Contains a significant initial protein, thereby deleting the putative anchoring region of the PSMA membrane. A protein called PSMA-like protein, Genbank accession No. AF261715, is nearly identical to amino acid 309-750 of PSMA and has a different expression profile (expression profile). Thus the most preferred epitopes are those containing the N-terminus located at amino acids 58-308.
PRAME, also known as MAPE, DAGE and OIP4, was originally observed as a melanoma antigen. Later, it has been considered a CT antigen, but unlike many CT antigens (e.g. MAGE, GAGE, and BAGE), it is expressed in acute myeloid leukemia. PRAME is a member of the MAPE family, which is composed primarily of hypothetical proteins with which PRAME shares limited sequence similarity. The use of PRAME as a TuAA is taught in U.S. patent 5,830,753 entitled "ISOLATED NUCLEIC ACID MOLECULES CODING FOR turbine detection anti gene precorresor DAGE AND USES theroflf".
PSA, prostate specific antigen, is a peptidase of the kallikrein family and a differentiation antigen of the prostate. Expression in breast tissue has also been reported. Alternative names include gamma-seminoprotein, kallikrein 3, seminogelase, seminin and the P-30 antigen. PSA has a high degree of sequence identity to the various alternative splice products prostate/gland kallikreins-1 and-2 and kallikreins 4, which are also expressed in prostate and breast tissue. Other kallikreins generally share less sequence identity and have different expression profiles. However, cross-reactivity that may be triggered by any particular epitope, as well as the possibility that the epitope will be released by processing in non-target tissues (most commonly by housekeeping proteasomes) should be considered in designing the vaccine.
PSCA, a prostate stem cell antigen, also known as SCAH-2, is a differentiation antigen that is preferentially expressed in prostate epithelial cells and overexpressed in prostate cancer. Low levels of expression are found in some normal tissues including neuroendocrine cells of the digestive tract and the collecting ducts of the kidney. PSCA is described in us patent 5,856,136 entitled "HUMAN STEM CELL ANTIGENS".
Synaptonemal complex protein 1(SCP-1), also known as HOM-TES-14, is a meiosis-associated protein and is also a cancer-testis antigen (Tureci, O., et al Proc. Natl. Acad. Sci. USA 95: 5211-. As a cancer antigen, its expression is not regulated by the cell cycle and is often found in gliomas, breast, kidney cells and ovarian cancers. It has some similarity to myosin, but has a small enough identity that cross-reactive epitopes are not directly searchable (immediatate promoter).
The ED-B domain of fibronectin is also a potential target. Fibronectin undergoes developmentally regulated alternative splicing, with a single exon used primarily in fetal Cancer tissues encoding the ED-B domain (Matsuura, H.and S.Hakomori Proc.Natl.Acad.Sci.USA 82: 6517-.
The ED-B domain is also expressed in fibronectin of the neovasculature (Kaczmarek, J. et al int.J.cancer 59: 11-16, 1994; Castellani, P. et al int.J.cancer 59: 612. minus 618, 1994; Neri, D. et al Nat.Biotech.15: 1271. minus 1275, 1997; Karelina, T.V. and A.Z.Eisen cancer Detect.Prev.22: 438444, 1998; Tarli, L. et al Blood 94: 192. minus 198; 1999; Castellani, P. et al Acta neurohir. (Wien) 142: 277. minus 282, 2000). As a fetal cancer domain, the ED-B domain is commonly found in fibronectin expressed by neoplastic cells in addition to being expressed by neovasculature. Therefore, CTL-inducing vaccines targeting the ED-B domain may exhibit two mechanisms of action: directly lysing tumor cells and disrupting the blood supply to the tumor by disrupting tumor-associated neovasculature. Because CTL activity decays rapidly after vaccine administration, interference with normal angiogenesis can be minimized. Designing and testing VACCINES targeting NEOVASCULATURE is described in provisional U.S. patent application No. 60/274,063 entitled "ANTI-NEOVASCULATURE VACCINES FOR CANCER" and even U.S. patent application No. 10/094,699 entitled "ANTI-NEOVASCULATURE preportions FOR CANCER," filed on even date (3/7/2002) with the present application, attorney docket No. CTLIMM.015A. A tumor cell line is disclosed in provisional U.S. patent application No. 60/363,131, entitled "HLA-TRANSGENIC MURINE TUMOR CELL LINE," attorney docket number CTLIMM.028PR, filed 3/7/2002.
Carcinoembryonic antigen (CEA) is a typical carcinoembryonic protein that was first described in 1965 (Gold and Freedman, J.exp.Med.121: 439-462, 1965. more complete references can be found in Online medial initiative in Man; record 114890). It has been formally renamed carcinoembryonic antigen-associated cell adhesion molecule 5(CEACAM 5). Its expression is strongly associated with adenocarcinoma of the epithelial layer (epithelial lining) in the digestive tract and fetal colon. CEA is a member of the immunoglobulin supergene family and is a defining member of the CEA subfamily (defining member).
HER2/NEU is an epidermal growth factor receptor-associated oncogene (van de Vijver, et al, New Eng.J.Med.319: 1239-1245, 1988) and apparently identical to the c-ERBB2 oncogene (Di Fiore, et al, Science 237: 178-182, 1987). Overexpression of ERBB2 has been implicated in neoplastic transformation of prostate cancer. As HER2, it was amplified and overexpressed in 25-30% of breast cancers in other tumors where expression levels correlated with tumor aggressiveness (Slamon, et al, New Eng.J.Med.344: 783-792, 2001). In Online medial initiative in Man; a more detailed description is available in the record 164870.

Example 1
Preparation of epitopes
A. Artificial production of epitopes
Synthesis of a peptide comprising SEQ ID NO: 1, 8, 9, 11-23, 26-29, 32-44, 47-54, 56-63, 66-68, 88-253, or 256-588. After synthesis, peptides are cleaved from their supports with trifluoroacetic acid or hydrogen fluoride, respectively, in the presence of an appropriate protective scavenger. After removal of the acid by evaporation, the peptide was extracted with ether to remove the scavenger, and then the crude precipitated peptide was lyophilized. The purity of the crude peptide was determined by HPLC, sequence analysis, amino acid analysis, equilibrium ion content analysis and other appropriate methods. If the crude peptides are sufficiently pure (greater than or equal to about 90% purity), they can be used as is. If purification is required to meet pharmaceutical specifications, the peptide is purified using one or a combination of the following: then precipitating; reversed phase, ion exchange, size exclusion or hydrophobic interaction chromatography; or a counter-current distribution.
Pharmaceutical preparation
GMP-grade peptides are formulated in parenterally acceptable aqueous, organic or aqueous-organic buffers or solvent systems in which they remain physically and chemically stable and bioavailable. In general, buffers or combinations of buffers and organic solvents are suitable. The pH range is typically 6-9. Organic modifiers or other excipients may be added to help solubilize and stabilize the peptide. These include detergents, lipids, co-solvents, antioxidants, chelating agents and reducing agents. In the case of a lyophilized product, sucrose or mannitol or other lyophilized acids may be added. Peptide solutions are sterilized by membrane filtration in their final container-sealed system and lyophilized for clinical dissolution or storage until use.

7 the sequence of the insert EP2-UB-EP1 was confirmed by DNA sequencing.
Example 2
Identification of effective epitope variants
FLPWHRLFLL (SEQ ID NO.1) of the 10-mer was identified as a valid epitope. Based on this sequence, a number of variants were prepared. Variants that show activity in HLA binding assays (see example 3, part 6) were identified as effective and subsequently bound to vaccines.
HLA-A2 binding of FLPWHRLFLL length variants has been evaluated. Proteasome digestion analysis indicated that the C-terminus of 9-mer FLPWHRLFL (SEQ ID NO.8) was also produced. In addition, 9-mer LPWHRLFLL (SEQ ID NO.9) could also be generated by N-terminal pruning of the 10-mer. Both were predicted to bind to HLA-a0201 molecules, however of these two 9-mer FLPWHRLFL showed more significant binding and was preferred (see figures 3A and B).
In vitro proteasome digestion and N-terminal pool sequencing elucidate tyrosinase207-216(SEQ ID NO.1) tyrosinase to tyrosinase207-215(SEQ ID NO.8) was produced more generally, however the latter peptides showed superior immunogenicity which may be of concern in achieving optimal vaccine design. FLPWHRLFL, tyrosinase207-215(SEQ ID NO.8) for HLA-A2+In vitro immunization of blood to produce CTLs (see CTL induction culture below). Peptide-pulsed T2 cells were used as targets in a standard chromium release assay and were found to be inhibited by tyrosinase207-215(SEQ ID NO.8) induced CTL recognizes tyrosinase equally well207-216(SEQ ID NO.1) (see FIG. 3C). These CTLs also recognized HLA-A2+Tyrosinase + tumor cell lines 624.38 and HTB64, but did not recognize HLA-a2 of 624.28, 624.38-Derivatives (FIG. 3C)). The relative number of these two epitopes produced in vivo is therefore not a problem in vaccine design.
CTL induction culture
PBMCs from normal donors were purified from buffy coat by centrifugation in Ficoll-Hypaque. All cultures were performed using Autologous Plasma (AP) to avoid exposure to possible heterologous pathogens and recognition of FBS peptides. To facilitate the in vitro generation of peptide-specific CTLs, we used autologous Dendritic Cells (DCs) as APCs. DCs were generated and CTL was induced with DCs and peptides derived from PBMCs as described (Keogh et al, 2001). Briefly, monocyte-enriched cell fractions were cultured with GM-CSF and IL-4 for 5 days and cultured in medium containing 2. mu.g/ml CD40 ligand for an additional 2 days to induce maturation. Co-culture of 2X10 in 2ml RPMI supplemented with 10% AP, 10ng/ml IL-7 and 20IU/ml IL-2 in 24-well plates6Enriched CD8+And 2x105DC/well of peptide pulse. Cultures were restimulated with self-irradiated peptide-pulsed DC on days 7 and 14.
Sequence variants of FLPWHRLFL were constructed as follows. Consistent with the table of binding coefficients (see table 3) derived from the NIH/BIMAS MHC binding prediction program (see reference in example 3 below), binding can be improved by changing one anchor position to V by changing L at position 9. Although usually to a lesser extent, the coupling may also be changed by a change in the non-anchoring position. Referring generally to table 3, binding can be improved by using residues with a relatively large index. Regardless of their effect on MHC binding, changes in sequence may also alter immunogenicity. Thus binding and/or immunogenicity may be improved as follows:
by replacing P at position 3 with F, L, M, W, or Y; these are bulky residues that can also improve immunogenicity regardless of the effect on binding. Residues with amine and hydroxyl groups, Q and N, S and T, respectively, can also elicit strong cross-reactive responses.
By replacing W at position 4 with D or E to improve binding, this addition of negative charge can also make the epitope more immunogenic, and in some cases reduce cross-reactivity with the native epitope. Alternatively conservative substitutions F or Y may elicit a cross-reactive response.
Binding was improved by replacing H at position 5 with F. H can be considered to be partially charged and thus the loss of charge can hinder cross-reactivity in some cases. Substitution of a sufficiently charged residue R or K at this position can enhance immunogenicity without destroying charge-dependent cross-reactivity.
By replacing R at position 6 with I, L, M, V, F, W, or Y. The same caveats as for position 5 and alternatives apply here.
Binding was improved by replacing L at position 7 with W or F. The reduction of binding affinity at this position V, I, S, T, Q, or N substitution is not generally predicted by this model (NIH algorithm), however, as discussed above may be advantageous.
Y and W, which are Fs, preferably at positions 1 and 8, can elicit significant cross-reactivity. Finally, although substitutions in the direction of bulk are generally biased toward improved immunogenicity, it may be effective to substitute smaller residues such as A, S and C at positions 3-7, in terms of size contrast, rather than being bulky in nature, which is a theory of importance for immunogenicity. The reactivity of thiol groups in C can be introduced as described in Chen, j. -l., et al j.immunol.165: 948 955, 2000, among other features discussed above.

Cluster analysis (SSX-2)31-68)
1. Epitope clustering region prediction:
and (3) a computer algorithm: book "MHC Ligands and Peptide Motifs" SYFPEITHI based on H.G.Rammensee, J.Bachmann and S.Stevanovic (Internet Access http:// syfpeiti.bmi-heidelberg.com/Scripts/MHCServer.dll/EpPredict.htm); and in Parker, k.c., et al, j.immunol.152: 163, 1994 (NIH) (Internet access http:// bimas. dcrt. NIH. gov/molbio/HLA _ bin); was used to analyze the protein sequence of SSX-2 (GI: 10337583). EPITOPE clustering (regions containing higher than average density of peptide fragments with high predicted MHC affinity) was defined as fully described in U.S. patent No.09/561,571, entitled "epitop CLUSTERS," filed on 28.4.2000. Cutoff using epitope density ratio (cutoff) of 2, 5 and 2 clusters were defined using syfpetii and NIH algorithms, respectively, and peptide score cutoff was 16 (syfpetii) and 5 (NIH). Peptide scoring highest using NIH algorithm, SSX-241-49With an estimated dissociation half-life > 1000min, no overlap of any other predicted epitope in the NIH assay but indeed with SSX-257-65And (4) clustering.
2. Peptide synthesis and characterization:
SSX-2 Synthesis by MPS (Multiple Peptide Systems, San Diego, CA 92121) Using Standard solid phase chemistry31-68YFSKEEWEKMKASEKIFYVYMKRKYEAMT KLGFKATLP (SEQ ID NO. 10). According to the "proof of analysis" provided, the peptide was 95% pure.
3. And (3) proteasome digestion:
proteasomes were isolated from human erythrocytes using the proteasome isolation protocol described in U.S. patent application No.09/561,074 entitled "METHOD OF epidopediscovery," filed on 28.4.2000. SDS-PAGE, Western blotting, and ELISA were used as quality control assays. The final concentration of proteasome was 4mg/ml, determined by a non-interfering protein assay (Geno Technologies Inc.). Proteasome was stored in 25 μ l aliquots at-70 ℃.
The mixture is subjected to SSX-231-68Dissolved in Milli-Q water to prepare 2mM stock solution and store 20. mu.l aliquots at-20 ℃.
1 tube of proteasome (25 μ l) was removed from the-70 ℃ storage and thawed on ice. It was then mixed thoroughly with 12.5 μ L of 2mM peptide by repeated pipetting (the sample was kept on ice). Immediately after mixing, 5 μ L of sample was taken and transferred to a tube containing 1.25 μ L10% TFA (final TFA concentration of 2%); t ═ 0min samples. The proteasome digestion reaction was then initiated and performed in a programmed thermal controller at 37 ℃. Additional 5 μ L samples were taken at 15, 30, 60, 120, 180 and 240min, respectively, and the reaction was terminated by adding the samples to 1.25 μ L10% TFA as before. The samples were kept on ice or frozen until analysis by MALDI-MS. All samples were retained and stored at-20 ℃ for HPLC analysis and N-terminal sequencing. Peptides alone (without proteasome) were used as blanks: mu.L peptide + 4. mu.L Tris buffer (20mM, pH 7.6) + 1.5. mu.L TFA.
MALDI-TOF MS measurement:
for each time point, 0.3. mu.L of matrix solution (10mg/ml of AcCN/H of alpha-cyano-4-hydroxycinnamic acid) was first introduced2O solution (70: 30)) was applied to the sample slide, and then an equal volume of digested sample was gently mixed with the matrix solution on the slide. Slides were air dried at room temperature for 3-5 minutes before mass spectra were obtained. MS was performed on a Lasermat 2000MALDI-TOF mass spectrometer calibrated with peptide/protein standards. To improve the accuracy of the measurement, the molecular ion weight (MH) of the peptide substrate was determined+) Used as an internal calibration standard. Mass spectra of digested samples are shown in fig. 4 at T120 min.
MS data analysis and epitope identification:
to specify the measured Mass peaks, all possible fragments (N-and C-terminal ions, and internal fragments) and their corresponding molecular weights were generated using the computer program MS-Product, a tool derived from UCSF Mass Spectrometry Facility (accessible at http:// promoter. UCSF. edu/ucsfhtml3.4/msprod. htm). Average molecular weights are used due to the sensitivity of the mass spectrometer. As summarized in table 4, the mass peaks observed during digestion were identified.
The C-terminal fragment with a sequence 8-10 amino acids long predicted to bind to HLA by SYFPEITHI or NIH algorithm was selected for further study. The digestion and prediction steps of the method may be effectively carried out in any order. Although the substrate peptides used in the proteasome digestion described herein are specifically designed to include predicted HLA-a2.1 binding sequences, actual or predicted binding of actual digestion products to other MHC molecules can be detected afterwards. The selected results are shown in table 5.
TABLE 4 SSX-231-68Mass peak identification
Bold sequences correspond to peptides predicted to bind to MHC.
This peak can also be assigned to peptides 32-50 based on mass alone, however, it is less likely that proteasomes will remove only the N-terminal amino acid. N-terminal sequencing (below) confirmed that the sequence was 31-49.
Based on mass the fragments may also represent 33-68. The following N-terminal sequencing was consistent with determinations of 31-65.
TABLE 5 prediction of HLA binding by proteasome generated fragments
Unpredicted
As shown in Table 5, the addition of the authentic sequence (the authentic sequence) to the N-terminus of the epitope can generate epitopes against the same or different MHC restriction elements. Of particular note is the pairing of (K) RKYEAMTKL (SEQ ID NOS 19 and (20)) with HLA-B14 in which the 10-mer has a longer predicted dissociation half-life than the co-C-terminal 9-mer. Also note the case of 10-mer KYEAMTKLGF (SEQ ID No.21), which can be used as an effective vaccine against several MHC classes by relying on N-terminal pruning to generate epitopes against HLA-B4403 and-B08.
HLA-A0201 binding assay:
candidate epitopes KASEKIFYYV, SSX-2 were determined using variants of the method of Stauss et al (Proc Natl Acad Sci USA 89 (17): 7871-5 (1992)))41-49(SEQ ID NO.15) binding to HLA-A2.1. Specifically, T2 cells expressing empty or labile MHC molecules on their surface were washed twice with Iscove's Modified Dulbecco's Medium (IMDM) and plated in 96-well flat-bottom plates at 3x105Cells/200 μ l/well were cultured overnight in serum-free AIM-V medium (Life Technologies, inc., Rockville, MD) supplemented with 3 μ g/ml human β 2-microglobulin, and peptides at 800, 400, 200, 100, 50, 25, 12.5 and 6.25 μ g/ml were added. The peptides were mixed with the cells by repeated pipetting (alternatively the peptides could be added to separate wells) before dispensing to the plate, and the plate was gently shaken for 2 minutes. 5% CO at 37 ℃2The incubator of (1). The following day unbound peptides were removed by washing twice with serum-free RPMI medium and saturating amounts of anti-HLA class I monoclonal antibody, Fluorescein Isothiocyanate (FITC) -conjugated anti-HLAA 2, a28(One Lambda, candida Park, CA) were added. After incubation at 4 ℃ for 30min, cells were washed 3 times with PBS supplemented with 0.5% BSA, 0.05% (w/v) sodium azide, pH 7.4-7.6 (staining buffer). (alternatively W6/32(Sigma) can be used as an anti-HLA class I monoclonal antibody, cells washed with staining buffer, incubated with Fluorescein Isothiocyanate (FITC) -conjugated sheep F (ab') anti-mouse-IgG (Sigma) for 30min at 4 ℃ and washed 3 times as above). Cells were resuspended in 0.5ml of stainIn a buffer. Analysis of surface HLA-a2.1 molecules stabilized by peptide binding was performed by flow cytometry using a FACScan (Becton Dickinson, San Jose, CA). If flow cytometry is not performed immediately, cells can be fixed by adding one-quarter volume of 2% paraformaldehyde and storing at 4 ℃ in the dark.
The results of the experiment are shown in fig. 5. Discovery of SSX-241-49(SEQ ID NO.15) binds to HLA-A2.1 to the extent of a known A2.1 conjugate FLPSDYFPSV (HBV) used as a positive control18-27(ii) a SEQ ID NO: 24) similarly. HLA-B44 binding peptide, AEMGKYSFY (SEQ ID NO: 25) was used as a negative control. The fluorescence obtained from the negative control was similar to the signal obtained when the peptide was not used in the assay. The positive and negative control peptides are selected from Table 18.3.1 of Current Protocols in Immunology p.18.3.2, John Wiley and Sons, New York, 1998.

Anaesthetize and avoid the lateral tail vein at the caudal base, 100 μ l SSX-2 containing 100nmol was used41-49(SEQ ID NO.15) and 20. mu.g of HTL epitope peptide in PBS emulsified with 50. mu.l of IFA (incomplete Freund's adjuvant) were injected subcutaneously into HHD1 transgenic A x 0201 mice (Pascolo, S., et al, J.exp.Med.185: 2043-.
B. Preparation of stimulatory cells (LPS blasts)
Spleens from 2 naive mice (nasal mice) were used for each group of immunized mice, the naive mice were sacrificed and the carcasses were placed in alcohol. Using a sterile instrument, the epithelial layer of the skin on the left side (lower middle portion) of the mouse was punctured, exposing the peritoneum. The peritoneum was saturated with ethanol and the spleen was removed aseptically. The spleens were placed in culture dishes containing serum-free medium. Splenocytes were isolated by triturating the spleen using a sterile plunger from a 3ml syringe. Dish wells were rinsed and splenocytes collected in serum-free medium in 50ml conical tubes. Cells were centrifuged (12000rpm, 7min) and washed once with RPMI. In RPMI-10% FCS (tires)Bovine serum) to a concentration of 1x10 per ml6A cell. Lipopolysaccharide 25g/ml and dextran sulphate 7. mu.g/ml were added. In the presence of 5% CO2The cells were incubated in T-75 flasks at 37 ℃ for 3 days. Splenocytes were collected in 50ml tubes, centrifuged (pelleted) (12000rpm, 7min), and resuspended at 3X10 in RPMI7And/ml. Embryonic cells were pulsed with 50. mu.g/ml priming peptide (priming peptide) at room temperature for 4 hours, treated with mitomycin at 25. mu.g/ml C37 ℃ for 20min, and washed three times with DMEM.
C. In vitro stimulation
Antigen-exposed mice (14 days post immunization) were sacrificed as above to remove spleens 3 days after LPS stimulation of embryonic cells and on the same day as peptide loading. Mix 3x106Spleen cells and 1x106LPS embryonic cells/well in 24-well plates in DMEM medium at 5% CO2At 37 ℃ in DMEM medium supplemented with 10% FCS, 5X10-5M beta-mercaptoethanol, 100. mu.g/ml streptomycin and 100IU/ml penicillin. 5% (vol/vol) ConA supernatant was added to the culture on day 3 and on day 751Cytolytic activity was determined in a Cr-release assay.
D. Chromium release assay to measure CTL activity
To assess peptide specific lysis, 2 × 10 was used6T2 cells were incubated with 100. mu. Ci of sodium chromate plus 50. mu.g/ml peptide for 1 hour at 37 ℃. During the incubation period, they were gently shaken every 15 minutes. After labeling and loading, cells were washed 3 times with 10ml DMEM-10% FCS and each tube was wiped with a fresh Kimwipe after the supernatant was run off. Target cells were resuspended in DMEM-10% FBS at 1X105And/ml. Effector cells were adjusted to 1x10 in DMEM-10% FCS7100 μ l series of 3-fold dilutions of effectors were made in U-bottom 96-well plates. Add 100. mu.l of target cells per well. To determine spontaneous and maximal release, 6 additional wells containing 100 μ l of target cells were prepared for each target. Spontaneous release was shown by incubating the target cells with 100 μ l of medium; maximum release was shown by incubating the target cells with 100 μ l 2% SDS. Then the flat plate 600rpm centrifuge for 5min and 5% CO2And incubated at 37 ℃ for 4 hours under 80% humidity conditions. After incubation, the plates were then centrifuged at 1200rpm for 5 min. The supernatants were harvested and counted in a gamma counter. Specific lysis was determined as follows: % specific release ═ [ (experimental release-spontaneous release)/(maximum release-spontaneous release)]x100。
The results of the chromium release assay demonstrating target cell-specific lysis of peptide pulses are shown in fig. 6.
8. Cross-reactivity with other SSX proteins:
SSX-241-49(SEQ ID NO.15) shares high sequence identity with the same region of other SSX proteins. The surrounding regions are also usually already well conserved. Therefore, the housekeeping proteasome can be at V in all 5 sequences49And then cutting. In addition, SSX-2 is predicted41-49Binds to HLA-a0201 (see table 6). By using SSX-241-49The CTLs produced by immunization cross-react with tumor cells expressing other SSX proteins.

N-terminal pool sequencing (pool sequence) analysis
One aliquot of proteasome digested for one hour (see example 3, part 3 above) was subjected to N-terminal amino acid sequence analysis by an ABI 473A protein sequencer (Applied Biosystems, Foster City, Calif.). Determination of cleavage sites and efficiency is based on consideration of the sequencing cycle (sequence cycle), the repetitive yield of the protein sequencer and the relative yield of unique amino acids in the analyzed sequence. I.e., if the only (in the sequence analyzed) residue X is present only in the nth cycle, a cleavage site is present N-1 residues before it N-terminal. In addition to helping to resolve any misreadings in the assignment of masses to sequences, these data also provide a more reliable indication of the relative yields of various fragments than mass spectrometry.
For PSMA163-192(SEQ ID NO.30) the pool sequencing supports sequencing at V177Rear single mainCleavage site and several minor cleavage sites, especially in Y179The latter one. Review the results presented in fig. 7A-C show the following:

The digestion and prediction steps of the method may be effectively carried out in any order. Although the substrate peptides used in the proteasome digestion described herein are specifically designed to include predicted HLA-a1 binding sequences, actual or predicted binding of actual digestion products to other MHC molecules can be detected afterwards.

As shown in Table 10, appending authentic sequences to the N-terminus of an epitope can often produce an epitope that is still effective against the same or different MHC restriction elements, or even better. Note for example the pairing of (G) LPSIPVHPI with HLA-a0201, where 10-mer can be used as an effective vaccine against several MHC types by relying on N-terminal pruning to generate epitopes against HLA-B7, -B5101, and Cw 0401.

In this case it can be seen that the peptide reactive T cells are at 2.2x104One-half to 6.7x104One-half of the frequency is present in the culture.

Vaccination with a epitope vaccine.
1. Vaccination with peptide vaccine:
A. intra-nodal delivery
A formulation comprising a peptide in an aqueous buffer containing an antibacterial agent, an antioxidant and an immunomodulatory cytokine is injected into the inguinal lymph node for several consecutive days using a micropump system (MiniMed; Northbridge, CA) developed for insulin delivery. The infusion period was chosen in order to mimic the kinetics of antigen presentation in natural infections.
B. Controlled release of a substance
Peptide formulations are delivered using controllable PLGA microspheres known in the art that alter the pharmacokinetics of the peptide and improve immunogenicity. The preparation can be injected or orally administered.
C. Particle gun delivery
A peptide formulation was prepared in which the peptide was attached to gold particles as known in the art. The particles are delivered in a gene gun, which is accelerated at high speed to penetrate the skin, carrying the particles into the skin tissue containing pAPCs.
D. Aerosol delivery
The peptide formulation is inhaled as an aerosol known in the art for absorption into the appropriate vascular or lymphatic tissue in the lung.
2. Vaccination with nucleic acid vaccines
Nucleic acid vaccines are injected into lymph nodes using a micropump system, such as a MiniMed insulin pump. To mimic the kinetics of antigen presentation in natural infections, a nucleic acid construct formulated in an aqueous buffer containing an antibacterial agent, an antioxidant and an immunomodulatory cytokine is delivered over an infusion period of several days.
Optionally, the nucleic acid construct is delivered using a controlled release substance, such as PLGA microspheres or other biodegradable substances. These substances are injected or orally administered. Nucleic acid vaccines are administered using oral delivery to elicit an immune response by absorption in GALT tissue. Alternatively, the nucleic acid vaccine is delivered using a gene gun, wherein the nucleic acid vaccine is adhered to fine gold particles. The nucleic acid construct may also be inhaled as an aerosol for uptake into appropriate vascular or lymphatic tissue in the lung
Example 9
Determining the efficacy of epitope vaccines
1. Tetramer analysis:
a class I tetramer assay was used to determine T cell frequency in animals before and after administration of housekeeping epitopes. Clonal expansion of T cells in response to the epitope revealed that the epitope was presented by pAPCs to the T cells. Specific T cell frequencies for housekeeping epitopes were measured before and after administration of the epitopes to animals to determine whether the epitopes were presented on pAPCs. An increase in the frequency of epitope-specific T cells following administration indicates that the epitope is presented on pAPC.
2. Proliferation assay:
approximately 24 hours after inoculating the animals with the housekeeping epitope, pAPCs were harvested from PBMCs, splenocytes, or lymph node cells using monoclonal antibodies against the specific label present on the pAPCs immobilized on magnetic beads for affinity purification. pAPCs are enriched from crude blood or spleen cell preparations using this technique. The enriched pAPCs are then used in a proliferation assay for T cell clones that have been generated and are specific for the housekeeping epitope of interest. pAPCs were co-incubated with T cell clones and T cell proliferation activity was monitored by measuring incorporation of T cell radiolabeled thymidine. Proliferation indicates that T cells specific for the housekeeping epitope are being stimulated by the epitope on pAPCs.
3. Determination of chromium release:
human patients or non-human animals genetically engineered to express human MHC class I are immunized with housekeeping epitopes. T cells derived from immunized subjects were used in standard chromium release assays using human tumor targets or targets engineered to express the same MHC class I. The T cell killing objective indicates that stimulation of T cells in the patient will effectively kill tumors expressing a similar TuAA.
Example 10
Induction of CTL responses with naked DNA by intralymph node immunization is effective.
To quantitatively compare CD8 induced by different routes of immunization+CTL responses used a plasmid DNA vaccine (pEGFPL33A) containing a full characterizationcharaterized) derived from LCMV-glycoprotein (G) (gp 33; immunodominant CTL epitopes of amino acids 33-41) (Oehen, S., et al., Immunology99, 163-16992000) because this system allows for a broad assessment of the anti-viral CTL response. Groups of 2C 57BL/6 mice were immunized with a titrated dose (200-0.02 μ g) of pEGFPL33A DNA or the control plasmid pEGFP-N3, which was administered i.m. (intramuscularly), i.d. (intradermally), i.spl. (intrasplenic), or i.ln. (intralymph node). Positive control mice received 500pfuLCMV (intravenously). 10 days after immunization, splenocytes were isolated and assayed for gp 33-specific CTL activity after a second restimulation in vitro. As shown in fig. 15, the i.m. or i.d. immunization induced a weak detectable CTL response when high doses of pEFGPL33A DNA (200 μ g) were administered. In contrast, immunization with 2. mu.g pEFGPL33A DNA alone i.spl. and with as little as 0.2. mu.g pEFGPL33A DNA i.ln. elicited effective gp 33-specific CTL responses (FIG. 15; symbols indicate individual mice, and one of three similar experiments is shown). Immunization with control pEGFP-N3DNA did not elicit any detectable gp 33-specific CTL response (data not shown).
Example 11
DNA immunization in lymph nodes elicits anti-tumor immunity
To examine whether the effective CTL response elicited after i.ln. immunization could confer protection against peripheral tumors, groups of 6C 57BL/6 mice were immunized 3 times with 10 μ g of pEFGPL33A DNA or control pEGFP-N3DNA at 6 day intervals. After 5 days of the last immunization, small pieces of solid tumor expressing the gp33 epitope (EL4-33) were transferred s.c. to the two flanks and tumor growth was measured every 3-4 days. Although the EL4-33 tumors grew well in mice that had been repeatedly immunized with the control pEGFP-N3DNA (fig. 16), mice immunized with pEFGPL33A dnai. ln. quickly eradicated the peripheral EL4-33 tumors (fig. 16).
Example 12
Differences in DNA content in lymph nodes reflect differences in CTL responses within lymph nodes and after intramuscular injection.
i.ln or i.m. injection of pEFGPL33A DNA and purification of the DNA at 6, 12, 24,plasmid content of the injected or draining lymph nodes was assessed by real-time PCR after 48 hours and 4 and 30 days. After i.m. injection, the plasmid DNA content of the injected lymph nodes was approximately 3 orders of magnitude greater than that of the draining lymph nodes at 6, 12 and 24 hours. No plasmid DNA was detected in the draining lymph nodes at the subsequent time points (fig. 17). This is consistent with the use of i.m. injection requiring a3 order greater dose to achieve similar levels of CTL activity compared to i.ln. Same i.ln. injection of CD8-/-Knockout mice, which do not develop a CTL response against this epitope, show that the clearance of DNA from lymph nodes is not due to CD8+CTLs kill cells in lymph nodes. This observation also supports the conclusion that i.ln. administration will not provoke immunopathological damage to lymph nodes.
Example 13
DNA plasmid formulation for therapeutic vaccine against melanoma administered to human
SYNCHROTOPE TA2M, a melanoma vaccine encoding HLA-A2-restriction tyrosinase epitope SEQ ID NO.1 and epitope clustering SEQ ID NO.69, was formulated in 1% benzyl alcohol, 1% ethanol, 0.5mM EDTA, citrate-phosphate, pH 7.6. For loading into the MINIMED 407C infusion pump, aliquots of 80, 160 and 320. mu.g DNA/ml were prepared. The catheter of the silouette infusion device was placed in the inguinal lymph node visualized by ultrasound imaging. The pump and infusion set assembly was originally designed for delivery of insulin to diabetic patients, replacing the usual 17mm catheter with a 31mm catheter for this application. The infusion device was left open for 4 days (about 96 hours) at an infusion rate of about 25 μ l/hour, resulting in a total infusion volume of about 2.4 ml. Thus for the 3 concentrations mentioned above, the total dose administered for each infusion was about 200 and 400 μ g, respectively; and may be 800. mu.g. The infused subjects were given a 10 day rest period before beginning a subsequent infusion. Given the sustained retention of plasmid DNA in lymph nodes following administration (as in example 12) and the general response kinetics of CTLs after antigen elimination, this schedule will be sufficient to maintain immune CTL responses.
Example 14
Epitope tag
The methods described above, particularly in examples 3-7, have been applied to additional synthetic peptide substrates, which resulted in the identification of further epitopes as in tables 15-36 below. The substrate used here is designed to identify the products of housekeeping proteasome processing that produce HLA-a0201 binding epitopes, however, as described above, additional MHC-binding reactivity can be predicted. However, many such reactivities are disclosed, and these lists are intended to be exemplary, rather than exhaustive and limiting. As also discussed above, the individual components of the analyte may be used in varying combinations and sequences. Digestion of the NY-ESO-1 substrates 136-163 and 150-177 (SEQ ID NOS.254 and 255, respectively) produced fragments that did not fly well in MALDI-TOF mass spectrometry. However they are well suited for N-terminal peptide pool sequencing, thereby allowing the identification of cleavage sites. Not all substrates necessarily meet the formal definition of epitope clustering cited in example 3. Some clusters are so large, e.g. NY-ESO-186-171To make it more convenient to use a substrate that spans only a portion of the cluster. In other cases, the substrate extends beyond the cluster that satisfies the formal definition to include the adjacent predicted epitope. In some cases, the actual binding activity may have determined what substrates, such as the MAGE epitopes reported here, were prepared prior to designing the synthetic substrates, where HLA binding activity was determined to select peptides with predicted affinity.
Example 15
Assessment of epitope Cross-reactivity to non-target tissues
As mentioned above, PSA is a member of the kallikrein family of proteases, which is itself a subtype of the serine protease family. Although members of this family that share the greatest degree of sequence identity with PSA also share similar expression profiles, proteins that may have significantly different expression profiles share a separate sequence of the expression profile. The first step in assessing unwanted cross-reactivity is to identify shared sequences. One way to accomplish this is to BLAST Search for epitope sequences on SWISSPROT or Entrez non-redundant peptide sequence databases using the "Search for short near exact matches" option; hypertext transfer protocol is accessible over the world wide web (http:// www) "ncbi. Thus, a search of SEQ ID NO.214, WVLTAAHCI (human-limited records) for SWISSPROT found four exact matches, including PSA. The other 3 are derived from kallikrein 1 (tissue kallikrein), and elastase 2A and 2B. Although these 9 amino acid segments are identical, the flanking sequences are completely different, particularly on the C-terminal side, suggesting that different processing can occur and thus the same epitope may not be released from these other proteins. (please note that kallikrein nomenclature is confused). Kallikrein 1[ accession number P06870] is thus a protein different from that mentioned above in relation to the PSA paragraph in the section on tumor-associated antigens [ accession number AAD13817 ]).
This possibility can be checked in several ways. Synthetic peptides containing epitope sequences embedded within the context of each of these proteins can be subjected to in vitro proteasome digestion and analysis as described above. Alternatively, to determine whether an epitope is processed and presented, CD8 recognizing the epitope is being utilized+Cells expressing these other proteins by natural or recombinant expression can be used as targets in cytotoxicity (or similar) assays of T cells.
Example 16
Epitope clustering
Known and predicted epitopes are often unevenly distributed in the protein antigen sequence. As described above, we have defined epitope clusters that contain sequence segments that are more dense than the average density of (known or predicted) epitopes. The use of epitope clustering is to incorporate their sequences into the substrate peptides used in the proteasome digestion assay described herein. Epitope clustering can also be used as a vaccine component. A more thorough discussion of EPITOPE clustering definition and use is found in U.S. patent application No.09/561,571, entitled EPITOPE CLUSTERS.
The following tables (37-60) show the epitope densities of the 9-mer epitope and overlapping epitope regions predicted to be bound by HLA-A2 using SYFPEITHI and the NIH algorithm, as well as the epitope densities of the epitopes throughout the protein, and the ratio of these two densities. (the ratio must exceed 1 to cluster by definition above; requiring a higher value for this ratio reflects a preferred embodiment). Individual 9-mer were identified by scoring permutations and by their first amino position in the complete protein sequence. The numbering is derived from each possible cluster of proteins. The range of amino acid positions within the complete sequence that a cluster contains is expressed as the rank of the individual predicted epitope that makes up it.
