摘要 目的:观察Ⅱ型胶原蛋白对胶原诱导的关节炎(CIA)大鼠外周血CD4+CD25+FOXP3+调节性T细胞(Treg)的影响。方法:建立Ⅱ型胶原蛋白诱导的大鼠类风湿性关节炎(CIA)模型。采用流式细胞术分别检测正常对照组、模型组、Ⅱ型胶原蛋白治疗组和雷公藤多苷组大鼠外周血CD4+CD25+FOXP3+Treg的水平。结果:与正常对照组比较,模型组大鼠外周血CD4+T细胞亚群中CD25+FOXP3+Treg的水平明显下降(P<0.05或P<0.01);与模型组比较,Ⅱ型胶原蛋白治疗组大鼠外周血CD25+FOXP3+Treg显著升高(P<0.05或P<0.01);而CD25+FOXP3-T细胞和CD25-FOXP3+T细胞的水平则明显下降(P<0.05或P<0.01)。结论:II型胶原蛋白治疗CIA大鼠的可能途径是升高外周血CD4+CD25+FOXP3+Treg的水平。
