Abstract： 目的:了解实验性自身免疫性葡萄膜炎(experimental autoimmune uveitis,EAU)不同进展阶段小鼠T细胞动态变化,对葡萄膜炎治疗方案的优化及疗效评价提供指导.方法:用CFA+PTX+IRBP对6~10周龄雌性C57BL/6小鼠后肢及尾部皮下进行三点免疫建立EAU模型,于免疫3,7,14,21,28d取外周血行流式细胞术检测.结果:用特异性抗原IRBP免疫后,EAU疾病在第14d左右产生,在第21d达最高峰,以后开始逐渐缓解.随着EAU疾病的发生,CD4+CD25+调节性T细胞、CD4+CD3+辅助T细胞数量均有增加,CD4+CD25+调节性T细胞增加更为明显,CD4+CD25+Foxp3+调节性T细胞数量第21d达到高峰,第28d开始下降,CD4+CD25+Foxp3+/CD4+CD25-Foxp3+比值从第3d开始逐渐增加,到第21d达到高峰,从第28d开始下降.结论:EAU疾病的发生和转归与CD4+CD25+/-Foxp3+Treg细胞密切相关,CD4+CD25+/-Foxp3+Treg细胞为阐明EAU的缓解机制、预防和治疗人类葡萄膜炎提供了新思路.
