Abstract:
Self and non-self recognition is the key mechanism by which the immune system determines whether or not to mount an immune response. During pregnancy the maternal immune system must tolerate the persistence of non-self semi-allogeneic fetal cells in the maternal tissue. Although many mechanisms have been shown to contribute to the prevention of a destructive maternal immune response to fetal cells, the immune acceptance of the allogeneic fetus in pregnancy largely remains an immunological paradox (Billingham et al., 1953). The aim of this review is to describe the expression of the polymorphic histocompatibility antigens at the fetal-maternal interface, their interaction with maternal leukocytes and their possible roles in immune regulation at the fetal-maternal interface during human pregnancy.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
