Liver Int:孕酮受体的突变使HIV阳性的患者易感戊型肝炎

2018-01-23 MedSci MedSci原创

研究发现,孕酮的一个突变,为免疫抑制个体易感HEV感染,提供了一个研究思路。

免疫缺陷宿主感染戊型肝炎病毒(HEV)可导致慢性肝病。在移植受者中,使用某些免疫抑制剂和饮食习惯被认为是感染HEV的危险因素。在人类免疫缺陷病毒(HIV)感染的个体,HEV感染的危险因素尚不清楚。本研究的目的是研究在艾滋病毒阳性的个体中,孕酮受体(PROGINS)基因突变与HEV感染间的关系。

研究通过KASP对64名HIV阳性的患者和187例健康对照者的血清样本进行评估,评估PROGINS出现的频率。采用ELISA方法,检测IL-10、IL-12的血清水平。同时进行外周血T细胞刺激实验,以评估存在PROGINS基因突变患者的免疫反应。

研究发现,在HIV患者中,PROGINS突变与HEV血清阳性率显著相关(30% in HIV+/HEV+ versus 2% in HIV+/HEV, P = .009)。研究进一步发现,存在PROGINS突变的HIV+/HEV+患者,血清IL-10的血清水平降低,IL-12的血清水平增高。与未突变患者相比,PROGINS的突变,导致了患者对CD4+和CD8+T细胞的刺激反应减弱,这表明PROGINS与免疫调节有关。

研究发现,孕酮受体的一个突变,为免疫抑制个体易感HEV感染,提供了一个研究思路。
