摘要

背景:重症肌无力(MG)是一种自身免疫性疾病,由针对骨骼肌的乙酰胆碱受体(AChR)的抗体介导。已发现各种T辅助(Th)细胞,包括Th1,Th2,Th17,Th22和滤泡辅助T(TFH)细胞的失衡与免疫功能障碍有关。 目的:本研究旨在探讨Th细胞在MG患者外周血中的作用。 材料与方法:共有33名MG患者和34名年龄匹配的对照组参加了这项研究。使用Ficoll-Paque密度梯度离心法分离外周血单个核细胞(PBMC)。通过测定细胞标志物CD4,CXCR5,CD45RO,CD45RA和ICOS和PD-1的水平,使用流式细胞术分析了PBMC中TFH细胞的比例。血清中IFN-γ,IL-4,IL-17和IL-21的水平通过细胞计数微珠阵列分析。通过ELISA分析血清IL-22水平。 结果:PBMCs中TFH细胞的频率高于健康人,并且与MG患者的严重程度相关。 MG患者血清中促炎细胞因子IFN-γ,IL-17和IL-21水平升高,而MG患者与对照组之间IL-4和IL-22水平无显着差异。 结论:我们的发现提示MG患者的Th细胞及其细胞因子平衡与MG疾病的临床状况或严重程度有关。
