摘要(Abstract):
目的 :研究Th1型 /Th2型细胞因子对人孕早期蜕膜细胞活性及TGFβ1和PRL分泌的影响。方法 :蜕膜细胞活性采用MTT法进行检测 ,蜕膜组织分泌TGFβ1和PRL的活性分别采用ELISA法和RIA进行分析测定。结果 :Th1型细胞因子IFNγ低浓度时 ( 1~ 10ng/ml)对蜕膜细胞活性及PRL分泌有促进作用 (P <0 .0 5 ) ,高浓度时 ( 10 0~ 10 0 0ng/ml)则有抑制作用 (P <0 .0 1) ;IFNγ在一定剂量范围内 ( 10~ 10 0 0ng/ml)还可抑制TGFβ1的分泌 (P <0 .0 1)。而Th2型细胞因子IL 4在一定浓度范围内 ( 1~ 10ng/ml)可明显促进蜕膜的分泌活性 (P <0 .0 1)。结论 :Th1型 /Th2型细胞因子可能是通过影响蜕膜细胞活性及TGFβ1和PRL分泌而在早期妊娠中起重要的免疫调节作用
