摘要 目的:观察青藤碱(SN)对类风湿关节炎(RA)患者外周血环瓜氨酸肽抗原特异性T细胞(CCP-AST)分泌γ干扰素(IFN-γ)及白细胞介素-4(IL-4)水平的影响。方法:体外分离、培养RA患者外周血淋巴细胞,分为四组,空白组:不加任何干预药物;环胍氨酸肽(CCP)组:仅加CCP干预(CCP终浓度为20μg/ml);甲氨喋呤(MTX)对照组:同时加CCP与MTX干预(CCP与MTX终浓度均为20μg/ml);SN组:同时加CCP与SN干预(SN与CCP终浓度均为20μg/ml);体外培养72 h后,用酶联免疫吸附法(ELISA)检测细胞培养上清液中IFN-γ、IL-4分泌水平。结果:CCP干预后,RA患者外周血(PBL)淋巴细胞分泌的IFN-γ水平升高(P<0.05),IL-4水平下降(P<0.05);加入SN后,RA患者PBL源CCP-AST分泌的IFN-γ水平下调,IL-4水平升高,有显著性差异(P<0.01,P<0.05)。结论:SN可抑制RA患者CCP-AST分泌IFN-γ水平,上调IL-4的表达,这可能是SN治疗RA的免疫机制之一。
