In a study carried out in a group of 61 pregnant women in the 21st to the 41st week of gestation and comparatively in 9 nonpregnant controls, the following were determined: changes in the leukocyte and lymphocyte count, proportion of T cell rosettes, T1 rosettes (TM cells), T2 rosettes (TG cells), EAC rosettes (B cells), EACD rosettes (killer cells), circulating NBT-positive phagocytes, serum IgG, IgA, IgM and C3 concentrations, 50% hemolytic activity of the complement system. The results are interpreted in the light of present data regarding the mechanisms of ovo-embryo-fetal allograft.

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.

Transcytosis of IgG
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...
