摘要
采用流式细胞仪,~(3)H-TdR掺入和酶联免疫打点(ELISPOT)方法,研究妊娠免疫学指标的改变。妊娠晚期大鼠脾脏单个核细胞表面分子主要组织相容性抗原II(MHC II)明显下调,外周血单个核细胞表达CD11c明显减少,共激活分子B7-1和B7-2未见改变;脾脏和外周血单个核细胞中Th2细胞因子IL-10、IL004表达增多,TGF#beta#阳性细胞数也明显增加,而Th1细胞因子IFN#gamma#的产生未受抑制。此外,脾脏和外周血中单个核细胞的抗原特异性增殖未见改变,而腹腔淋巴结细胞的增殖明显升高。脾脏单个核细胞在妊娠晚期分泌较少的抗原特异性抗体。提示妊娠期性激素具有免疫调节作用,可能与怀孕时Th1细胞介导的自身免疫性疾病得到缓解有关。

Abstract
These data indicate the immunomodulatory effects of sex-hormones in pregnancy, which may be related to the remission of T cell-mediated autoimmune diseases during pregnancy.
