摘要:

为探讨山羊子宫内膜细胞和性腺激素对子宫自然杀伤(uNK)细胞分泌血管内皮生长因子(VEGF)和γ-干扰素(IFN-γ)含量的影响。本研究以永生化山羊子宫内膜基质细胞(ESC)和上皮细胞(EEC)为体外研究模型,通过ELISA法检测子宫内膜细胞和性腺激素(E2 和P4)对uNK细胞分泌VEGF和IFN-γ含量的影响。结果显示,在uNK细胞与EEC共培养时,雌激素E2单独或与P4共同作用可显著抑制uNK细胞中IFN-γ和VEGF分泌水平(P<0.05),而P4单独作用不显著;而当uNK细胞与ESC共培养时,孕酮P4单独或与E2共同作用可显著增强IFN-γ在uNK细胞中的分泌水平(P<0.05),而E2单独或与P4共同作用可显著抑制VEGF分泌水平(P<0.05)。研究结果表明性腺激素对与 EEC或ESC共培养的uNK细胞分泌水平具有不同程度的调节作用。

Abstract:

 To explore the effects of goat endometrial cells and sex hormones on secretion content of VEGF and IFN-γ in uNK cells. Using immortalized goat endometrial stromal cells (ESC) and epithelial cells (EEC) as an in vitro research model, the effects of the endometrial cells and sex hormones (E2, P4) on secretion content of VEGF and IFN-γ in uNK cells was detected by ELISA assay. When uNK cells co-cultured with EEC, estrogen alone or together with P4 significantly inhibited the secretion levels of IFN-γ and VEGF in uNK cells (P<0.05), while the P4 alone had no significant effect. When uNK cells co-cultured with ESC, P4 alone or together with E2 can significantly enhance the secretion of IFN-γ in uNK cells (P<0.05), whereas E2 alone or together with P4 significantly inhibited the secretion level of VEGF (P<0.05). These results indicated that the sex hormones play a role in regulatoring secretion of uNK cells co-cultured with EEC or ESC.
