Diagram illustrating the immune cells at maternal–fetal interface. A large number of immune cells, including macrophages, T cells, dendritic cells, γδT cells, NK cells are present in decidua. They have capabilities of secreting cytokines, chemokines, and angiogenic mediators, and establishing interactions with other decidual cells. These functional immune cells are essential for maintaining the immune balance at maternal-fetal interface. Among them, decidual NK cells make remarkable contributions to spiral artery remodeling, trophoblast invasion processes, prevention of pathogenic invasion of fetal placenta, as well as decidualization, which play indispensable roles in pregnancy success. dNK cell, Decidual NK cell
