Abstract

Maternal immune tolerance of the fetus is indispensable for a healthy pregnancy. Currently, the study of the immune microenvironment of the maternal-fetal interface has been a heated topic in reproductive immunology research. More and more studies show that the immune imbalance in the maternal-fetal interface plays a very important role in the incidence of intrahepatic cholestasis of pregnancy (ICP). However, the precise etiology and mechanism of immune imbalance in the occurrence of ICP is still unknown. In order to clarify the potential immunologic mechanisms of ICP, this review summarizes the recent studies of the decidual immunology microenvironment and the potential immunologic mechanisms related to the development of ICP.

Keywords: Intrahepatic cholestasis of pregnancy; Decidual lymphocytes; Trophoblast; Human lymphocyte antigen-G

Core tip: In this paper, we reviewed the recent publications regarding the role of immunological interactions at the maternal-fetal interface on the occurrence of intrahepatic cholestasis. The literature shows that the decidual immunological microenvironment may relate to the development of intrahepatic cholestasis of pregnancy. Any approach that modulates immune tolerance at the maternal-fetal interface toward the natural state could provide insight in the treatment of intrahepatic cholestasis of pregnancy.
