Abstract:
The immunoglobulin G (IgG) and complement C3 (C3) were measured in the maternal as well cord blood sera of 30 cases of pregnancy induced hypertension (PIH) as well as 9 controls with normotensive pregnancy. A depression of IgG as well as C3 level was observed in the maternal as well as cord sera of the mothers with PIH. These findings suggest decreased immunological status of both mother and her offspring in PIH, irrespective of the gestation and intrauterine growth status.

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.
Subsequent T...
