摘要

Background: RIF is clinically defined as the failure of good quality embryos to implant into the uterus following at least three cycles of In Vitro Fertilization/Embryo Transfer (IVF/ET). During human pregnancy, a genetically different fetus is allowed to survive within the uterus despite the maternal recognition of fetal alloantigens. Compared with normal pregnant women, early loss of embryo is associated with systemic lower levels of Treg cells in IVF. Moreover, several lines of evidence have indicated that differentiation of naive T cells into Th17 is deleterious for normal pregnancy and may cause implantation failure. Sirolimus as the most common mTOR (mammalian target of Rapamycin) inhibitor is able to effectively prevent allograft rejection. Here we aimed to evaluate Sirolimus effects on Th17/Treg axis and subsequently on pregnancy outcome.
