1Isolation and characteristics of autoreactive T cells specific to aggrecan G1 domain from rheumatoid arthritis patients显示文摘Our previous work showed that the cartilage proteoglycan aggrecan could induce an erosive polyarthritis and spondylitis in BALB/c mice and the GI globular domain of the aggrecan (GI) contained the arthritogenic region. To elucidate whether autoreactive T cells to G1 are expressed in rheumatoid arthritis patients, we analyzed the frequency of human G1-specific T cells in the peripheral blood of five rheumatoid arthritis patients and tried to establish G1-reactive T cell lines from these rheumatoid arthritis patients. The results showed that the G1-specific T cells in PBL were detectable at the range of 4.97 ±0.5 ×10-6 in peripheral blood lymphocytes. We have also generated 15 G1-specific T lymphocyte lines from these pateints with a standard split-well method. All these cells expressed fine specificity to human recombinant G1, but not to unrelated antigen. All the 15 lines expressed a panT cell marker and 13 of them selectively used the αβ T cell receptor. Two of them used rye T cell receptor. The 13 of these T cell lines was CD4 positive. One line expressed CD8. One line expressed both CD4 and CD8. Moreover, 14 out of 15 lines expressed the Th-1 cytokine profile, characterized by interferon-γpositivity and IL-4 negativity. No Th-2 type cell line was generated. These data provide strong evidence in favor of the presence of autoreactive T cells in the rheumatoid arthritis pateints. What is the mechanism(s) that these autoreactive T cells attack self-target and whether these G1-specific, Th-1 type T cell lines can induce arthritis in immune deficiency mice are currently under investigation.LI NING LI DONG QING ZHANG KUANG YAN ZHOU ANNIE CARTMAN JEAN YVES LEROUX A ROBIN POOLE YI PING ZHANG ( Shanghai Institute of Immunology, Shanghai Second Medical University, Shanghai 200025, China)(Joint Diseases Laboratory, Shriners Hospital, Dep 2000Cell Research2000,10,1:7
2人rG1特异反应性T细胞生物学特性的研究显示文摘目的分析重组人软骨抗原凝集原 (rG1 )体外诱导建立的 1 1株rG1特异性T细胞株的生物学特性。方法采用直接标记免疫荧光法对rG1特异性T细胞株进行表型分析 ;采用QuantikineELISAKits定量检测细胞培养上清液中的IFN -γ与IL - 4;采用RT -PCR方法分析其BV的限制性取用。 结果所建细胞株均表现为CD3阳性 (98.6 %± 1 .5 % ) ,大部分细胞株 (9/ 1 1 )为CD4阳性 (97.1 %± 2 .5 % ) ,而其余 2株为CD4和CD8混合表达 ,其中CD4阳性为 82 .95 % ,CD8阳性为 36 .5 0 %。 8株分泌IFN -γ(5 44± 390 pg/ml) ,而IL - 4阴性 ,为Thl细胞 ;1株同时分泌IFN -γ和IL - 4,为Th0细胞 ;2株细胞未测出IFN -γ和IL - 4分泌 ;无Th2细胞株出现。所有T细胞株均选择性取用αβ(97.4%± 2 .4% )TCR受体。 结论所建立的rG1特异性T细胞株经表面鉴定为纯度很高的CD3阳性T细胞 ,多表现为CD4阳性 ,细胞因子分泌类型多属Th1T细胞。陈雪华 李宁丽 刘炳亚 朱正钢 Annie Cartman 张一平 2000上海交通大学学报(医学版)2000,24,S1:0
