子痫前期中PD-1/PD-L1信号通路对Treg/Th17免疫平衡调控的机制研究
发布时间:2020-12-05 07:27
第一部分PD-1、PD-L1、Foxp3和RORγt在子痫前期患者胎盘组织中表达的研究目的:通过检测PD-1与其配体PD-L1,以及Treg和Th17细胞的特异性核转录因子Foxp3和RORγt在子痫前期患者和正常孕妇胎盘组织中的表达水平及其差异,探讨PD-1/PD-Ll信号通路在子痫前期发病机制中的作用。方法:以正常晚孕妇女为对照组(n=16),临床确诊为子痫前期的患者为研究对象(n=10)。收集两组孕妇的胎盘,采用免疫组化法检测胎盘中PD-1、PD-L1、 Foxp3和RORγt蛋白的表达,荧光定量PCR法和Western blot法分别检测胎盘中PD-1、PD-L1、Foxp3和RORyγt mRNA和蛋白表达水平。结果:1.PD-1、PD-L1、Foxp3和RORγ蛋白在子痫前期患者和正常孕妇的胎盘组织中均有表达,PD-1和PD-L1主要位于胎盘绒毛滋养细胞中,主要在细胞浆和细胞膜中表达;Foxp3和RORγt主要位于胎盘绒毛滋养细胞及绒毛间质细胞中,主要在细胞核和细胞浆中表达。2.与正常妊娠组相比,子痫前期组胎盘中PD-1 mRNA表达水平明显降低(P<0.05),PD...
