Abstract

The invention discloses use of a soluble CTLA4 (cytotoxic T lymphocyte-associated antigen-4) molecule in the preparation of a drug for treatment of rheumatoid arthritis, and specifically provides the use of the soluble CTLA4molecule in preparation of the drug for treatment of active rheumatoid arthritis (ra) in adults, wherein biological or non biological preparation disease modifying anti-rheumatic drugs (DMARDs) have poor therapeutic effects on the active rheumatoid arthritis (ra) in adults, and the DMARDs can be one of amethopterin, cyclophosphamide, azathioprine, cyclosporine A or tumor necrosis factor alpha (TNF alpha) blocking agent or antagonist or a combination thereof. Preferably, the soluble CTLA4 molecule is CTLA4Ig. The experimental results show that CTLA4Ig can significantly improve the symptoms, physical signs and laboratory indicators of rheumatoid arthritis compared with placebo.

Description

Soluble CTLA 4 molecule is for the preparation of the purposes for the treatment of medicine for treating rheumatoid arthritis
Technical field
The invention belongs to field of biological pharmacy, more specifically, the invention discloses soluble CTLA 4 molecule for the preparation of the purposes in treatment immune disease medicine.
Background technology
Rheumatoid arthritis is a kind of progressivity rheumatism, and the adult of the Chinese Home that interferes with the development about 2% (Utsinger, P.D., et al., 1985Rheuma toid Arthritis, p.140).The feature of this disease is the struvite synovitis continued, and this causes the corrosion of cartilage and bone, thus causes the structural deformities in joint, periphery.Comprise arthroncus, joint tenderness, inflammation, morning stiff and pain with the symptom of rheumatoid arthritis, particularly bending time pain.The experimenter with advanced joint inflammation is subject to the impact of structural damage, comprises destruction of joint and bone corrosion (see Principals of Internal Medicine, Harrison, 13th edition, pages1648-1655).In addition, patient can also show other clinical symptoms of various organ lesion, comprises skin, pathological changes that kidney, heart, lung, central nervous system unify eye, and this is due to the vasculitis relevant to self-immunprocess.
Other symptom relevant to rheumatoid arthritis comprises erythrocyte sedimentation rate to be increased, and serum C-reactive protein (CRP) and/or IL-2 receptor (IL-2r) level raise.Erythrocyte sedimentation rate nearly all suffer from the patient of Active rheumatoid arthritis all increase.Serum C-reactive protein level also raises, and relevant with the probability that progressivity joint injury occurs to disease activity degree.In addition, the solubility IL-2f level that in the serum of Active rheumatoid arthritis patient and synovial fluid, a kind of T cell by activating produces also raises (see Principals ofInternal Medicine, Harrison, 13th edition, page1650).
Rheumatoid arthritis is also considered to the autoimmune disease of a kind of T cell mediation, and it relates to the antigen-non-specific cell-cell interaction between T lymphocyte and antigen-presenting cell.In general, the common stimulation responses that the intensity of t cell response is caused by the interaction between T cell surface molecular and its part measures (Mueller, et al., 1989Ann.Rev.Immunol.7:445-480).Crucial costimulatory signal is by its part on T cell surface receptor CD28 and CTLA4 and antigen-presenting cell, as the interaction between B7 correlation molecule CD80 (i.e. B7-1) and CD86 (i.e. B7-2) provides (Linsley, P.and Ledbetter, J.1993Ann.Rev.I mmunol.11:191-212).
When not stimulating altogether, the activation of T cell causes anergy t cell response (Schwartz, R.H., 1992Cell71:1065-1068), and wherein immune system becomes stimulation nonreply.
Because rheumatoid arthritis is considered to the disease of immune system of a kind of T cell mediation, a kind of strategy of the novel agent of exploitation treatment rheumatoid arthritis is qualification blocks the costimulatory signal between T lymphocyte and antigen-presenting cell molecule by the interaction blocked between endogenous CD28 or CTLA4 and B7.Possible molecule comprises modified and with the affinity higher than wild type CTLA4 or CD28 in conjunction with B7, thus blocks the soluble CTL A 4 of costimulatory signal.
The soluble form of CD28 and CTLA4, by merging variable region (V) like cell extracellular portion and immunoglobulin (Ig) constant region of CD28 and CTLA4, obtaining CD28Ig and CTLA4Ig and building.Nucleotide and the aminoacid sequence of CTLA4Ig are shown in Fig. 1, and this protein amino acid sequence, from the methionine of+1 or from the alanine of-1, stops with the lysine of+357.CTLA4Ig is relative to CD28Ig, and the combination of positive with CD80 in CD86 positive cell more by force (Linsley, P., et al., 1994Immunity1:793-80).Have been found that many T cell dependent immune response by CTLA4Ig in vivo with extracorporeal blocking (Linsley, P., et al., 1991b, supra; Linsley, P., et al., 1992a Science257:792-795; Linsley, P., et al., 1992b J.Exp.Med.176:1595-1604; Lenschow, D.J., et al.1992Science257:789-792; Tan, P., et al., 1992J.Exp.Med.177:165-173; Turka, L.A., 1992Proc.Natl.Acad.Sci.USA89:11102-11105).
The treatment of the rheumatism such as current rheumatoid arthritis comprises and gives nonspecific cytotoxicity immunosuppressive drug, as methotrexate, cyclophosphamide, azathioprine, Ciclosporin A and tumor necrosis factor α (TNF α) blocker or antagonist.These immunosuppressive drugs suppress the whole immune system of experimenter, and long-term prescription increases the risk infected.And these medicines only delay the progress of rheumatoid arthritis, when treating discontinuous, can recur at faster speed.In addition, the long-term treatment of these nonspecific drugs produces toxic side effects, comprises the tendency that some malignant tumor, diabetes and liver dysfunction occur.These medicines also can lose efficacy gradually after effective 2-5 (Kelley ' s Textbook of Rheumatology, 6thEdition, p1001-1022).
As selection, as the therapeutic agent of Non-specific immune suppression and anti-inflammatory agent for relief of symptoms.These medicines are dose dependents, can not prevent progression of disease.These medicines comprise steroid compound, as prednisone and methyl meticortelone.The life-time service of steroid is also with serious toxic side effects.(Kelley′s Textbook of Rheumatology，6thEdition，p829-833)。
Therefore, the treatment modest efficacy of current rheumatoid arthritis, causes serious toxicity side effect, and can not life-time service continuously.
Summary of the invention
The invention provides the method by giving experimenter's soluble CTLA 4 molecule treatment rheumatoid arthritis, the B7 molecule of this soluble CTLA 4 molecule on B7 positive cell is combined, thus suppresses CTLA4 and/or CD28 of endogenous B7 molecule in T cell to be combined.Soluble CTLA 4 molecule for the inventive method is CTLA4Ig.More preferably, the invention provides the activities of adults rheumatoid arthritis improving antirheumatic (DMARDs) unsatisfactory curative effect by giving the biological or non-biological agents state of an illness of experimenter's soluble CTLA 4 molecule treatment, wherein DMARDs can be methotrexate, cyclophosphamide, azathioprine, Ciclosporin A or tumor necrosis factor α (TNF α) blocker or antagonist one or a combination set of.
