title: The maternal immune system in health and disease.
abstract: Recent studies have clarified some characteristics of trophoblast and immune cells in the decidua and peripheral blood during pregnancy and the roles they play in the maternal immune system, and have added further evidence to the theory that maternal T helper cell type 1/2 cytokine balance shifts towards T helper cell type 2 dominance during pregnancy.
