人类女性生殖道 (FRT) 中细胞质模式识别受体 (PRR) NOD-1、NOD-2、RIG-1 和 MDA5 的表达模式和调节尚未阐明。用雌二醇、聚 (I:C)、淋病奈瑟菌 (GC) 和 HIV-1 处理从输卵管 (FT)、子宫内膜 (EM)、子宫颈 (Cx) 和子宫颈外 (Ecx) 分离的原代上皮细胞 (EC)。通过实时 RT-PCR 分析 PRR mRNA 表达。通过 ELISA 分析条件培养基的 IL-8。来自所有 FRT 区室的 EC 组成型表达 NOD1、NOD2、RIG-1 和 MDA5,其中 FT 表达水平最高。 Poly(I:C) 刺激导致所有 FRT 区室中 NOD2、RIG-1 和 MDA5 上调,并与 IL-8 分泌增加相关,而雌二醇治疗则没有效果。暴露于 GC 和 HIV-1 IIIB 而不是 BaL 会导致 NOD2 和 MDA5 选择性上调。 PRR 在整个 FRT 中表达,并受到 Poly(I:C)、GC 和 HIV-1 的差异调节。
Expression patterns and regulation of cytosolic pattern recognition receptors (PRR) NOD-1, NOD-2, RIG-1, and MDA5 have not been elucidated in the human female reproductive tract (FRT). Primary epithelial cells (EC) isolated from Fallopian tube (FT), endometrium (EM), cervix (Cx) and ectocervix (Ecx) were treated with estradiol, poly(I:C), Neisseria gonorrhea (GC), and HIV-1. PRR mRNA expressions were analyzed by Real-time RT-PCR. Conditioned media were analyzed for IL-8 by ELISA. EC from all FRT compartments constitutively expressed NOD1, NOD2, RIG-1, and MDA5 with highest levels expressed by FT. Stimulation with poly(I:C) resulted in upregulation of NOD2, RIG-1, and MDA5 in all FRT compartments and correlated with increased secretion of IL-8 whereas estradiol treatment had no effects. Exposure to GC and HIV-1 IIIB but not BaL resulted in selective upregulation of NOD2 and MDA5. PRR are expressed throughout the FRT and differentially regulated by poly(I:C), GC and HIV-1.
