Plasmodium falciparum-infected erythrocytes adhere both in the intervillous space and on the villous surface of human placenta by binding to the low-sulfated chondroitin sulfate proteoglycan receptor.
We recently reported that fetal DNA in maternal plasma is derived primarily from villous trophoblasts bordering the intervillous spaces, which are filled with maternal blood (13).
Because there is insufficient invasion of extravillous trophoblasts into the uterine vasculature, placental vascular resistance is not reduced; there thus is inadequate oxygenation of blood within the placental intervillous spaces that border villous trophoblasts.
