Preeclampsia and Increased Permeability Over the Blood-Brain Barrier: A Role of Vascular Endothelial Growth Receptor 2.

Background: Cerebral complications in preeclampsia are leading causes of maternal mortality worldwide but pathophysiology is largely unknown and a challenge to study. Using an in vitro model of the human blood-brain barrier (BBB), we explored the role of vascular endothelial growth factor receptor 2 (VEGFR2) in preeclampsia.

Methods: The human brain endothelial cell line (hCMEC/D3) cultured on Tranwells insert was exposed (12 hours) to plasma from women with preeclampsia (n = 28), normal pregnancy (n = 28), and nonpregnant (n = 16) controls.
