Deep trophoblast invasion in the placental bed has been considered the hallmark of human pregnancy. It occurs by two routes, interstitial and endovascular, and results in transformation of the walls of the spiral arteries as they traverse the decidua and the inner third of the myometrium. Disturbances in this process ...

There is a strong clinical association between intrauterine infections and pregnancy complications, such as preterm labor. The placenta functions as an active barrier whereby the trophoblast recognizes microbes through pattern recognition receptors, such as the well characterized Toll-like receptors, in order to respond to pathogens at the maternal-fetal interface. Consequently, ...
