摘要
目的研究伴胸腺瘤重症肌无力(myasthenia gravis,MG)患者外周血中Th17细胞及其相关细胞因子变化,探讨Th17细胞与MG疾病临床严重度及血清乙酰胆碱受体抗体(anti-acetylcholine receptor autoanti-bodies,AChR-Ab)水平的关系。方法采用流式细胞术检测MG患者及健康对照(对照组)外周血单个淋巴细胞悬液(PBMCs)Th17细胞比例,采用实时定量PCR方法检测PBMCs中Th17细胞相关细胞因子mRNA转录水平;采用ELISA法检测血清中Th17细胞相关细胞因子表达及AChR-Ab水平;使用美国重症肌无力协会QMG评分评价MG临床严重程度。结果 MG伴胸腺瘤组外周血Th17细胞比例〔(1.57±0.56)%〕显著高于对照组〔(0.94±0.32)%,P=0.031〕;MG伴胸腺瘤组IL-17mRNA转录相对水平(23.16±4.72)高于对照组(14.82±3.03,P=0.0083),IL-1βmRNA、IL-6mRNA、ROR-γmRNA、IL-23mRNA相对转录水平分别为7.36±2.14、8.96±1.93、18.46±2.11、1.32±0.25,均高于对照组(分别为4.61±1.68,P=0.039;4.61±1.68,P=0.037;0.78±0.25,P=0.028;12.84±2.97,P=0.041);MG伴胸腺瘤组血清IL-17表达量〔(30.0±7.2)pg/mL〕高于对照组〔(20.0±4.9)pg/mL,P=0.029〕,IL-1β、IL-23表达量分别为(72.0±11.5)、(208±85.6)pg/mL,均高于对照组〔分别(45.0±9.3)pg/mL,P=0.034;(93.0±48.3)pg/mL,P=0.004〕。伴胸腺瘤MG患者QMG评分与Th17细胞比例呈正相关(r=0.74,P=0.034)。MG患者外周血Th17细胞比例与血清AChR-Ab水平呈正相关(r=0.81,P=0.026)。结论 MG胸腺瘤中Th17细胞增多,可能导致免疫调节功能紊乱,从而引起MG发病。
