实验性自身免疫性葡萄膜视网膜炎 (EAU) 是一种由 S 抗原(一种视网膜感光细胞蛋白)诱导的 CD4+ T 细胞介导的自身免疫性疾病。为了鉴定负责致病性的 T 细胞识别位点,使用溴化氰片段和合成肽来测试针对天然 S 抗原制备的致葡萄膜炎 T 细胞系。已知可主动诱导 EAU 的两种非重叠合成肽并未在这些 T 细胞系中诱导增殖反应。相比之下,无法主动诱导 EAU 的相邻合成肽会引发 T 细胞系强烈的增殖反应,并产生葡萄膜炎细胞系。我们的结果表明,S 抗原中存在空间上不同的 T 细胞表位,这些表位负责 EAU 的主动诱导、淋巴细胞增殖以及过继转移 EAU 的能力。
Experimental autoimmune uveoretinitis (EAU) is a CD4+ T-cell mediated autoimmune disease induced by S-antigen, a retinal photoreceptor cell protein. In order to identify T cell recognition sites responsible for pathogenicity, cyanogen bromide fragments and synthetic peptides were used to test uveitogenic T cell lines prepared against native S-antigen. Two non-overlapping synthetic peptides known to actively induce EAU did not induce proliferative responses in these T cell lines. In contrast, an adjacent synthetic peptide which was unable to actively induce EAU elicited strong proliferative responses from the T cell lines and gave rise to a uveitogenic line. Our results indicate that spatially distinct T cell epitopes are present in S-antigen which are responsible for the active induction of EAU, lymphocyte proliferation, and the ability to adoptively transfer EAU.
