Description
描述
本发明涉及新的核酸序列,该序列编码针对血小板膜蛋白的人自身抗体并编码抗独特型抗体,本发明还涉及人抗体新的氨基酸序列,以及上述核酸序列和氨基酸序列在诊断和治疗疾病中的用途。
自身免疫性血小板减少性紫癜(AITP)是免疫病,其特征在于与正常或升高的巨核细胞生成相关的血小板数目降低。因抗血小板自身抗体的存在使得网状内皮系统(脾,肝脏和骨髓)中的血小板破坏增加。可在约75%AITP患者中检测到的这些自身抗体绝大多数针对的是血小板膜糖蛋白(GP)IIb/IIIa和Ib/IX。在一个和相同的患者中可发现几种不同的自身抗体特异性(参见Berchtold和Wenger,血液81(1993),1246-1250;Kiefel等,英国血液学杂志,79(1991),256-262;McMillan等,血液70(1987),1040和Fujisawa等,血液79(1991);1441)。然而,由于从AITP患者得到的自身抗体的量有限,目前仍难以鉴定结合表位并确定自身抗体的致病重要性。使用杂交瘤技术(Kunicki等,人抗体杂交瘤1(1990)83-95)仅能从AITP患者的淋巴细胞中得到一些可与GPIIb/IIIa AIPT反应的人单克隆抗体。
据报道,健康个体中也存在抗多种自身抗原的天然自身抗体,例如抗人血小板的细胞内和细胞骨架成分的自身抗体(Guilbert等,免疫学杂志,128(1982),2779-2787;Hurez等,欧洲免疫学杂志,23(1993),783-789和Pfueller等,临床实验免疫学,79(1990),367-373)。健康个体血清中存在的一些自身抗体也可抗血小板膜蛋白(Souberbielle,欧洲血液学杂志,56(1996),178-180)。然而,这些天然自身抗体的作用及其与疾病相关性自身抗体的关系仍是未知的。
皮质类固醇可用于治疗AITP,约一半患者在4周内对服用强的松产生反应;然而,长期减轻症状很少见。静脉内施用高剂量的免疫球蛋白(IVIgG)被推荐用于紧急治疗表现出严重出血或血小板数目极低的患者。大多数患者在接受这一治疗之后,血小板数目快速地,但通常为瞬时地增加。皮质类固醇和IVIgG在治疗AITP中的作用机理仍是未知的。Berchtold等(血液74(1989),2414-2417和Berchtold和Wenger,血液81(1993),1246-1250)进行的研究揭示出IVIgG中存在的抗独特型抗体可抑制自身抗体与血小板糖蛋白的结合。
本申请需解决的问题是鉴定新的DNA序列,该序列负责自身抗体与GPIIb/IIIa的结合。可使用此方法制备可用的新型药物制品,该制品可用于改善AITP的诊断和治疗。
令人惊奇地是:使用健康人供体的外周循环B细胞制备人抗体重链和轻链的组合噬粒展示文库之后,可以鉴定自身抗体的结合序列。人抗体重链和轻链Fab片断展示于丝状噬菌体M13的表面之后,可以鉴定出对GPIIb/IIIa表现出特异性结合的噬菌体克隆。
为此,将噬粒文库连续地与缺乏GPIIb/IIIa的血小板机能不全的血小板(负选择)和正常的血小板(正选择)接触。几轮选择和通过感染大肠杆菌进行扩增之后,得到23个克隆,它们能与GPIIb/IIIa复合物结合。使用针对GPIIb/IIIa的单克隆抗体库进行抑制研究,产生两组克隆:两组都被特异于GPIIb/IIIa复合物的单克隆抗体抑制,一组还被GPIIb特异性的单克隆抗体抑制。对克隆进行DNA分析,显示出2种不同的抗GPIIb/IIIa噬菌体克隆的存在,这进一步证实了上述发现。这些结果表明可从健康个体的基因组克隆2种GPIIb/IIIa特异性的噬菌体克隆,即自身抗体,这些克隆能识别属于GPIIb/IIIa复合物的构象表位。抑制研究还确定了两种噬菌体克隆都能抑制AITP患者的血小板相关性自身抗体与纯化的GPIIb/IIIa的结合,因此可能识别与AITP相关的GPIIb/IIIa表位。由于噬菌体克隆含有得自健康个体基因组之天然自身抗体的抗原结合序列,因此,此发现可导致对AITP中血小板相关性自身抗体的新认识。
另外,将抗GPIIb/IIIa噬菌体克隆用作抗原,可以使用这些新的噬菌体克隆产生针对抗GPIIb/IIIa自身抗体的重组型抗独特型抗体。以此方法得到的重组型抗独特型抗体构成了令人感兴趣的临床方法,可以替代IVIgG的使用。
序列表SEQ ID NO:1-8(自身抗体)和SEQ ID NO:9-18(抗独特型抗体)中显示了所鉴定的噬菌体克隆的核苷酸序列和由这些核苷酸序列推定的氨基酸序列。

在本发明的意义上,术语“人抗体链的功能性衍生物”指的是至少包括上文所定义的重链和/或轻链CDR3区域的多肽,适当时,该多肽与人抗体的相关互补链(或该链的衍生物)一起能形成抗体衍生物,该衍生物对抗原具有等同于非衍生化抗体所具有的识别特异性。优选这种抗体衍生物对相关抗原的结合常数至少为10-6l/mol,优选为至少10-8l/mol。
通过例如使用重组DNA技术缺失,取代和/或插入编码相关多肽的基因区段可制备人抗体链的功能衍生物。
单链抗体可由例如H和L链的可变区或者一个或两个H链结构域组成,适当时还可具有恒定区,这是特别优选的抗体链或抗体功能衍生物。这种构建体的制备描述于Hoogenboom等,免疫学评论,130(1992),41-68;Barbas III,Methods:Companion MethodsEnzymol,2(1991),119和Pluckthun,免疫化学(1994),MarcelDekker Inc.,第9章,210-235。
在本发明的意义上,术语“同等的结合能力”指的是结合亲和性和/或特异性(即表位识别)与具体公开序列所具有的相同。
本发明的另一部分主题是含有至少1拷贝新核酸的载体,此载体可以是原核载体或真核载体。质粒,粘粒和噬菌体是原核载体的例子,这种载体详细描述于例如Sambrook等,分子克隆,实验室手册,第2版(1989),冷泉港实验室出版社的第1-4章中。优选原核载体为质粒或噬菌体。
另一方面,载体也可以是真核载体,例如酵母载体,昆虫载体(杆状病毒)或哺乳动物载体(质粒载体或病毒载体)。真核载体的例子描述于Sambrook等,文献同上,第16章和Winnacker,基因和克隆,EineEinfuhrung fur die Gentechnologie[基因和克隆,基因工程导言](1985),VCH Verlagsgesellschaft,尤其是第5,8和10章。
本发明的另一部分主题是表达新核酸的细胞,或被新核酸或新载体转化的细胞。细胞可以是原核细胞(如革兰氏阴性细菌细胞,尤其是大肠杆菌)或真核细胞(如酵母,植物或哺乳动物细胞)。适当细胞和将新核酸导入这种细胞的方法的例子见于上述参考文献中。
本发明的另一部分主题是由新核酸编码的多肽,尤其是重组多肽。特别优选多肽含有人抗体H链和/或L链的可变区。
特别优选的是表现出抗体特性,其亚单位成分是重链或其功能衍生物和轻链或其功能衍生物的多肽。该多肽可由两个独立的链组成或以单链多肽的形式存在。
本发明的另一部分主题是抗新多肽的抗体,所述抗体针对的是负责识别抗原的多肽区域。此抗体可以是多克隆的抗血清,单克隆抗体或者多克隆或单克隆抗体的片断(如Fab,F(ab)2,Fab’或F(ab’)2片断)。优选此抗体针对的是新多肽抗体之重链和/或轻链CDR3区域,或其部分区域。通过用含有新CDR3区域的肽或多肽免疫实验动物,并从实验动物中分离所得的多克隆抗体,即可使用已知方法得到这种抗体。另外,根据Kohler和Milstein的方法或其改良方法,通过将实验动物中产生抗体的B细胞与白血病细胞融合可得到单克隆抗体。另外,通过以新多肽为抗原,筛选适当的噬粒文库,例如健康人供体的噬粒文库,也可得到针对新多肽CDR3区域的重组抗体。
本发明还涉及药物组合物,其含有上述核酸、载体、多肽、抗体或细胞作为有效成分,适当时还添加有其它活性成分和药学上常用的佐剂、添加剂或赋形剂。
该药物组合物可用于制备诊断或治疗剂。诊断用途的例子是诊断AITP或AITP诱因。另一个优选的诊断用途是监测AITP疾病的进程。
该药物组合物作为诊断剂的用途包括例如检测将新多肽表达为抗体的B细胞亚群。通过核酸杂交试验(适当时需先进行扩增)可在核酸水平上检测此抗体。另一方面,通过使用抗原或与多肽特异性反应的抗体进行的免疫测定法可在蛋白质水平上检测此抗体。
另外,该新的药物组合物也可用于治疗领域,尤其是预防或治疗AITP。此治疗用途可基于例如刺激抗自身抗体之抗体的产生。为此,可给患者施用新的自身抗体多肽,从而引发和/或刺激抗独特型抗体的形成。在此方面,根据常规的免疫方法即可进行给药(Fox等,J.Pharmacol.Exp.Ther.279(1996),1000-1008;Whittum-Hudson等,天然药物2(1996),1116-1121;Jardieu,免疫学最新观点,7(1995),779-782)。另一方面,通过施用适当的反义核酸可特异性地抑制抗体基因的表达。可给患者施用该新的抗独特型抗体多肽以直接抑制自身抗体的活性。
对新的自身抗体多肽的研究表明:这些多肽令人惊奇地可抑制血纤蛋白原与血小板的结合,因此,新的自身抗体多肽和抗独特型抗体多肽(适当时可联合使用这两种多肽)可在心肌梗塞或中风,或静脉形成血栓并发肺栓塞或局部缺血等之后用作调节血液凝结,尤其是预防血栓的药剂。
鼠单克隆抗体,如单克隆抗体7E3(参见美国专利5440020)或其片断(如可商购的Fab片断ReoPro),或短的合成肽已被用作血纤蛋白原的拮抗剂以用于治疗的目的。然而,鼠单克隆抗体和抗体片断的缺点在于具有免疫原性,当用于治疗人患者时会产生不必要的副反应,而短肽一般会很快地降解。与已知的药剂相比,该新多肽的优点在于它们由来源于人的氨基酸序列组成,因此表现出的不必要的副作用比相应的鼠抗体或抗体片断的小,而由于其大小比肽大,因此它不会象肽那样快速地降解。
因此,本发明涉及新的核酸、尤其是编码自身抗体多肽的核酸、含有此核酸的载体、被上述核酸或载体转化的细胞,由核酸编码的多肽、含有一种或多种上述物质的药物组合物用于制备影响尤其是抑制血纤蛋白原与血小板之结合的药剂的用途。优选使用药剂调节血液凝结,尤其是溶解血栓和/或防止血栓形成。根据已建立的鼠抗体或抗体片断的施用方法可施用该新的药物组合物。

实施例
1.鉴定自身抗体序列
1.1.分离自身抗体
自身抗体得自12个AITP患者(8个患原发性AITP,3个患与SLE相关的AITP,1个患与斯耶格伦综合征相关的AITP),制备方法如下:4℃下将患者血浆与纯化的GPIIb/IIIa保温过夜,随后于室温下用0.2mol/l甘氨酸和0.15mol/l NaCl,pH2.5洗脱15分钟。100,000g离心30分钟之后,用1mol/l Tris-HCl中和上清液,对Tris缓冲的盐溶液(TBS)透析过夜。
提取血浆时,所有患者皆为血小板减少症(血小板数目<150×109/l),其骨髓中的巨核细胞正常或增大,没有其它可测形式的免疫性血小板减少症。
1.2.分离纯化的抗原
所用抗原为纯化的GPIIb/IIIa,它是GPIIIa的胞质片断(氨基酸721-744)和GPIIIa的细胞外片断(氨基酸468-690)(Beardsley,Blut59(1989),47-51和Phillips等,酶学方法,215(1992),244-263)。
1.3.分离血小板以用于淘选和免疫印迹
通过差速离心取自健康人供体的经EDTA抗凝结的血样来制备富含血小板的血浆。通过2000g离心15分钟分离出血小板,然后用含有50mmol/l柠檬酸钠,100mmol/l NaCl和125mmol/l葡萄糖的柠檬酸缓冲液(pH6.2)洗涤6次,最后重新悬浮于相同缓冲液中。
使用相同的富集方法从患有格兰茨曼I型血小板功能不全病的14岁男孩体内得到功能不全的血小板。
1.4.单克隆抗体
使用了识别复合形式的GPIIb/IIIa的鼠单克隆抗体和选择性识别GPIIb或GPIIIa的抗体。这些抗体是使用相应的抗原,通过常规的免疫方法分离得到的,它们与AITP不相关。所述抗体的分离描述于Kouns等(生物化学杂志267(1992),18844-18851),Steiner等(Biochim.Biophys.Acta 1119(1992),12-21)和Haring等(美国国家科学院院报82(1985),4837-4841)。
1.5.噬粒文库
使用得自健康、预先免疫过的人供体的外周血淋巴细胞,根据Vogel等(欧洲免疫学杂志,24(1994),1200-1207)所述的方法制备组合Fab文库。除了Taq聚合酶(Perkin Elmer,NJ,USA)外,所有酶和寡核苷酸都得自Boehringer Mannheim GmbH(Mannheim,德国)。通过PCR扩增Fab分子H和L链的引物,VCSM13辅助噬菌体和大肠杆菌菌株XL-Blue都得自Stratacyte(La Jolla,CA,美国)。噬粒pComb3得自Scripps Research Institute(La Jolla,CA,美国)。按BarbasIII和Lerner(Methods:Companion Methods Enzymol,2(1991),119)所述进行克隆,转化至XL-Blue细胞和制备phab。用4%(w/v)聚乙二醇8000和3%(w/v)NaCl沉淀phab,重新悬浮于PBS,pH7.4中。所得表达文库含有1×107特异性。
1.6.分离GPIIb/IIIa特异性phab
利用总共5轮亲和选择(“淘选”)制备GPIIb/IIIa特异性phab。用5×107个功能不全的血小板预吸附(负选择)之后,将phab与108个正常的血小板一起保温45分钟(正选择)。然后用0.05mol/l柠檬酸钠,pH2.5洗脱结合的phab,并用1mol/l Tris缓冲液中和。每一轮淘选之后,通过滴定噬菌体集落形成单位监测GPIIb/IIIa特异性phab的富集。5轮选择之后,发现洗脱的phab被富集了100倍以上。
更仔细地分析第4轮选择之后所得phab库的GPIIb/IIIa特异性。为此,随机选择40个phab克隆,在免疫斑点试验中确定其结合特异性。将1微升正常的和功能不全的血小板(109个/ml),以及纯化的GPIIb/IIIa(500μg/ml)滴加至硝酸纤维素条上(Millipor公司,Bedford,MA,美国)。将条置于含0.15%酪蛋白的TBS(TBS-酪蛋白)中封闭,然后与用TBS-酪蛋白稀释的phab一起保温过夜。用TBS-0.1%吐温20(TBS-吐温)洗涤3次后,与用TBS-酪蛋白稀释1000倍的辣根过氧化物酶缀合的多克隆兔抗噬菌体抗体(Vogel等,文献同上)保温之后,用4-氯-1-α-萘酚(Merck,Darmstadt,德国)检测结合的phab。
还检测了滴加前通过加热(70℃)或酸处理(0.5N HCl,pH2)变性蛋白质之后phab与血小板和纯化的GPIIb/IIIa的结合。
在40个随机选择的克隆中,23个(57.5%)与GPIIb/IIIa反应,而17个未表现出任何结合。保温前通过加热或pH2处理变性抗原之后,未观察到抗GPIIb/IIIa与phab的结合,从而阐明phab的结合需要完整的GPIIb/IIIa。在阴性phab中检测Fab的存在情况揭示出15个克隆(88%)不含任何Fab分子。2个不与GPIIb/IIIa结合的Fab阳性克隆对GPIIb/IIIa可能有低结合亲和性。
1.7.Fab分析
为了检测阳性phab的κ,λ和Fd链,将抗GPIIb/IIIa phab滴加至硝酸纤维素上,将滤膜与已用TBS-酪蛋白稀释1000倍的经过氧化物酶标记的小鼠抗人λ,κ(The Binding Site Limited,Birmingham,英国)和Fd抗体(得自HP6045杂交瘤细胞系,ATCC1757,Rockville,MD,美国)保温4小时,然后通过化学发光法(ECL,Amersham,Switzerland,Zurich,Switzerland)显色。检测15个随机选择的抗GPIIb/IIIa Fab克隆的κ,λ和Fd链,结果表明Fd链存在于12个克隆(80%)中,而λ链存在于所有克隆中。
通过将集中的phab与多种浓度的血小板一起预保温以定量测定Fab与血小板上GPIIb/IIIa的结合。然后通过免疫斑点法分析上清液。在此方面,确定每个血小板结合1-3×104个phab。这表明每个血小板上约10-50%GPIIb/IIIa分子可以被phab占据。
1.8.鉴定phab结合表位
通过使用多种单克隆抗体(见1.4.)进行抑制试验来测定phab的表位特异性。在双份重复试验中,各将1微升融化的正常和功能不全的血小板(109个/ml),纯化的GPIIb/IIIa(500μg/ml),GPIIIa的肽片断(氨基酸468-690,500μg/ml)和GPIIb/IIIa的胞质区段(500μg/ml)滴加至硝酸纤维素条上。封闭后,将phab克隆(0.4μg/mlFab)在加或不加单克隆抗体(1μg/ml)的情况下保温过夜。使用经过氧化物酶标记的抗噬菌体抗体和4-氯-1-α-萘酚检测结合的phab。
在这些研究中鉴定出两组phab克隆,A组(5个克隆)被所有抗体的汇集物中度抑制,但被GPIIb/IIIa复合物特异性抗体强烈抑制。抗GPIIb抗体没有反应。B组(10个克隆)被所有抗体的汇集物完全抑制,但被复合物特异性抗体和IIb特异性抗体抑制的程度较低。两组与GPIIIa特异性的抗体都未表现出反应。使用血小板或纯化的GPIIb/IIIa作为抗原也得到相同的结果。未发现phab与胞质肽或GPIIIa的胞外片断结合。
这些结果概述于表1。

1.9.抑制试验
通过抑制试验测定抗GPIIb/IIIa phab对患者自身抗体与GPIIb/IIIa结合的封闭作用。为此,使用两个按上文所述鉴定的phab克隆(PDG16和PDG31)。
从1∶3至1∶1000连续稀释洗脱的患者自身抗体,分析其与纯化的GPIIb/IIIa的结合。通过免疫斑点试验可以实现此目的。在3份重复试验中,各将100ng纯化的GPIIb/IIIa滴加至硝酸纤维素条上,然后用TBS-酪蛋白封闭滤膜。为了用phab封闭AITP自身抗体与GPIIb/IIIa的结合,将滤膜条与1011个phab保温1小时,然后与不同稀释度的AITP自身抗体保温4小时。使用经过氧化物酶标记的抗人IgG-Fc抗体和ECL检测结合的自身抗体。
抗GPIIb/IIIa phab抑制得自8个AITP患者的自身抗体的结合。对PTG16,PTG31和两种phab的汇集物的抑制范围分别为10至46%,32至60%和20至67%。这些phab对得自4个AITP患者的自身抗体的结合没有影响。两组都含有得自原发性AITP患者和与疾病相关之AITP患者的自身抗体。
所得结果概述于表2。

2.鉴定抗独特型抗体序列
2.1 phab克隆AI-X
根据实施例1所述的方法,使用噬粒技术鉴定抗独特型抗体的序列。将实施例1中选定的克隆PDG16用作抗原,没有阴性的预先选择。
使用组合phab文库的汇集物测定外周血B淋巴细胞的非免疫文库和已被红细胞固定化的外周血淋巴细胞文库,和得自扁桃体的B淋巴细胞非免疫文库的特异性。
分析4轮淘选之后所得的phab库,为此,随机选择40个phab克隆,测定它们的结合特异性,选定克隆中有25个能与抗GPIIb/IIIaphab反应。这些抗独特型phab克隆属于两组:I组(3个克隆)仅与A组自身抗体phab克隆(PDG7,8,10和16)反应,而II组phab克隆(共22个克隆)与A组和B组phab克隆、鼠抗GPIIb/IIIa单克隆抗体、纯化的血清免疫球蛋白(IVIgG)或其F(ab’)2片断以及抗IgE Fab都能反应。14个phab克隆(III组)不与上述任何物质反应。1个IV组phab克隆仅与抗GPIIb/IIIa抗体反应。这些特异性试验的结果简述于表5a中。
对I组phab克隆(AI-X16,17和24)进行的DNA序列分析表明除了CDR2区域的1个氨基酸外,重链编码序列完全相同,而轻链编码序列完全相同。与已知株系基因序列的比较结果表明与VH3 H链序列约有85%的同源性,与V-λIIL链家族序列约有90%同源性。在II,III和IV组phab克隆中各取1个代表,对其进行H链基因的DNA序列分析,序列分析的结果和与已知株系基因序列的比较结果简述于表6和7a。
抑制试验的结果示于图1,利用免疫斑点试验测定纯化的GPIIb/IIIa对AI-X17与PDG-A结合的抑制作用。将660和220ng PDG-A phab分别滴加至硝酸纤维素滤膜上,将抗原与浓度范围为50μg/ml至50ng/ml的GPIIb/IIIa保温2小时,与缓冲溶液保温2小时作为对照,然后再与噬菌体克隆AI-X17(终浓度为1012/ml)保温2小时。使用过氧化物酶缀合的多克隆兔抗噬菌体抗体,通过电化学发光法检测结合的噬菌体。
发现AI-X17 phab(I组)能抑制A组抗体phab(PDG-X)与IIb/IIIa糖蛋白的结合,这证明AI-X17能识别PDG-A上的抗原结合位点。
测定结合PDG-A的另一个克隆AI-X2的序列,与克隆AI-X20,39和40类似,此克隆仅具有重链而无轻链。重链自身(可能是作为二聚体)能以足够的特异性和亲和性与抗原(即PDG-A)结合。
2.2 phab克隆AI-B
根据实施例2.1所述的方法,使用噬粒技术鉴定其它抗独特型抗体的序列,将实施例1中选择的克隆PDG-B用作抗原。
共选择40个phab克隆,测定其结合特异性。选定克隆中的34个与抗GPIIb/IIIa phab反应,这些抗独特型phab克隆属于3组:
I组(14个克隆)仅与B组抗体phab克隆反应,而II组phab克隆(共8个克隆)与A组和B组phab克隆均反应,III组phab克隆(共12个克隆)还与鼠单克隆抗GPIIb/IIIa抗体、纯化的血清免疫球蛋白(IVIgG)或其F(ab’)2片断以及抗IgE Fab反应。6个phab克隆(IV组)不与上述任何物质反应。这些特异性试验的结果简述于表5b中。
对I组phab克隆(AI-14,18,24和38)进行DNA序列分析的结果简述于表6和7b。克隆AI-B14,18和38仅具有重链。
AI-B14和17是相同的,AI-B34和40也与AI-B18相同。
AI-B phab对PDG-B与血小板之结合的抑制作用示于图2。利用流式细胞计数分析测定这种抑制作用。为此,使用辅助噬菌体作为对照,在存在或缺乏AI-Bphab时,将富含血小板的血浆(共107个血小板)与生物素化的PDG-B保温。用低聚甲醛固定血小板,用R-藻红蛋白(RPE)标记的链霉亲和素检测结合的PDG-B。FACScan仪器中的计数为10,000,记录荧光的平均值(±SD)。克隆AI-B18,24和38获得最强的抑制作用(>60%)。结合抑制作用表明AI-B克隆能与PDG-B上的抗原结合位点相互作用。

3.自身抗体多肽对血纤蛋白原与血小板之结合的影响
3.1方法
分析Fab与经EDTA预处理的血小板的结合
将富含血小板的血浆与10mM EDTA保温30分钟,加入生物素化的PDG-B和PDG-A多肽,室温下将混合物保温1小时,使用藻红蛋白标记的链霉亲和素通过流式细胞计数分析测定PDG-A和PDG-B与血小板的结合。
聚集实验
新鲜制备富含血小板的血浆(250×109/l),将其保存于5%CO2中。在缺乏或存在PDG-A或PDG-B的情况下(最大量为10微克Fab),通过不同稀释度的ADP(最大浓度为410μM)激活血浆。在Rodell 300BD-5aggregometer(Baxter AG,Dudingen,Switzerland)中测定聚集作用。在随后的实验中,加入PDG-A或PDG-B之后再将多克隆的抗Fab抗血清加入激活的血小板中。
血纤蛋白原结合试验
用0.5μg/ml GPIIb/IIIa包被ELISA板的孔,并用溶于Tris-缓冲盐溶液的3.5%牛血清白蛋白封闭之。在缺乏或存在PDG-A,PDG-B或作为对照的抗IgE Fab(最大浓度为23μg/ml)的情况下,以不同的浓度(最大为0.08μg/ml)加入血纤蛋白原(Kabi Diagnostics,Stockholm,Sweden)。用大鼠抗人血纤蛋白原抗体、生物素化的小鼠抗大鼠抗体和由链霉亲和素和生物素化的辣根过氧化物酶组成的缀合物(Amersham Pharmacia Biotech Europe GmbH,Dubendorf,Switzerland),使用ELISA Easy Reader(EAR340AT,SLT Instruments,Austria),在405nm下测定结合的血纤蛋白原。
使用单克隆抗体7E3和抗体片断ReoPro的竞争试验
在存在或缺乏鼠单克隆抗体7E3或其Fab片断ReoPro(Fab总量范围为1014至1010)的情况下,将富含血小板的血浆(230×109/l)与PDG-B或PDG-A(分别为200和400μg/ml)一起保温1.5小时。用等体积的1%低聚甲醛固定之后,使用藻红蛋白标记的链霉亲和素通过流式细胞计数分析测定PDG-B和PDG-A与血小板的结合。
3.2结果
检测的重组型抗GPIIb/IIIa Fab自身抗体片断未表现出与经10mM EDTA预处理的血小板的结合,这表明自身抗体片断仅识别构象完整的抗原(图3)。
在使用富含血小板之血浆的聚集实验中,PDG-A和PDG-B都不能抑制聚集。在血纤蛋白原的浓度比血清中的低104至106倍的血纤蛋白原结合试验中,PDG-A和PDG-B完全抑制血纤蛋白原的结合(图4)。当将使用类似的富集方法得到的抗IgE Fab用作对照时,没有抑制作用出现。这些结果表明PDG-A和PDG-B均与GPIIb/IIIa上的血纤蛋白原结合位点强有力地相互作用。
在用鼠单克隆抗GPIIb/IIIa抗体7E3或其可商购的Fab片断ReoPro进行的研究中,它们都能抑制血纤蛋白原与激活的GPIIb/IIIa结合,PDG-B与血小板的结合被选择性地和完全地抑制(图5和7)。与之形成对照的是,7E3或ReoPro都未显著抑制PDG-A与血小板的结合。
