1、免疫学杂志2011年9月第27卷第9期IMMUNOLOGICALJOURNALVol.27No.9Sep.2011·785··论著·[文章编号]1000-8861(2011)09-0785-04Th17细胞及相关细胞因子在自身免疫性甲状腺疾病中的变化及意义*陈紫君,刘纯,李强,田杰[摘要]目的探究Th17细胞及相关细胞因子IL-17、IL-6在自身免疫性甲状腺疾病中的变化及意义。方法收集49例初发自身免疫性甲状腺疾病患者,根据病情分为Graves病初发组和桥本甲状腺炎初发组,随访至治疗后甲状腺功能正常,另设健康对照组。采用流式细胞仪检测外周血中Th17细胞比例,用双抗体夹心酶联法检测血浆IL-
2、17、IL-6水平。结果IL-17和IL-6在Graves病初发组、桥本甲状腺炎初发组中均明显升高。IL-6在Graves病缓解组中明显下降。IL-17在Graves病缓解组中,桥本甲状腺炎缓解组并无明显下降。Th17细胞在Graves病初发组、桥本甲状腺炎初发组中明显升高。Th17细胞比例与IL-17水平呈正相关,与IL-6无相关性。在桥本甲状腺炎中,Th17和IL-17水平与自身抗体TPO-Ab、TG-Ab呈正相关,在Graves病中,Th17和IL-17水平与特异性抗体TRAB无相关性。结论Th17细胞可能参与了自身免疫性甲状腺疾病的发病,且与桥本甲状腺炎关系更为密切。[关键词]Th17
