摘要 目的:探讨人类白细胞抗原-G(HLA-G)在妊娠滋养细胞疾病中的表达及意义。方法:运用实时荧光定量RT-PCR技术分别检测18例部分性葡萄胎、19例完全性葡萄胎、19例侵蚀性葡萄胎、20例绒毛膜癌和20例正常妊娠绒毛组织中HLA-G mRNA的表达,HLA-G mRNA的表达以PCR循环数阈值(Ct值)表示。Western blot印迹法检测组织中HLA-G蛋白质的表达,同时运用双抗体夹心酶联免疫吸附(ELISA)法检测各组血浆中可溶性HLA-G(soluble HLA-G,sHLA-G)的表达水平。结果:各组组织中HLA-G mRNA、HLA-G蛋白质和血浆中sHLA-G的表达水平由弱至强依次为正常妊娠组、部分性葡萄胎组、完全性葡萄胎组、侵蚀性葡萄胎组、绒毛膜癌组。各组间HLA-G mRNA、HLA-G蛋白质和血浆中sHLA-G表达水平的差异均有显著性意义(P<0.05)。结论:在妊娠滋养细胞疾病的发生、发展过程中,滋养细胞通过上调HLA-G的表达水平实现免疫逃逸,有利于其异常增殖、浸润和转移。
