Abstract:
No other organ in the body undergoes such an invasion of selective cells (leukocytes) and release of homing molecules, CAMs, proinflammatory cytokines, and mediators or undergoes similar extensive remodeling of tissues over such a short period of time as the pregnant uterus. This is especially interesting, as an infectious process involving microorganisms does not exist in a healthy pregnancy and delivery. Furthermore, after delivery of the baby and placenta, the uterus involutes and returns to its normal monthly cycling, and most of the leukocytes are swept away or leave. In this review, we discuss leukocyte infiltration and recruitment and the potential roles of each subpopulation of leukocytes in relation to pregnancy and the problems of preterm birth, pre-eclampsia, and intrauterine growth restriction.

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...
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...

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
