Introduction
Several interesting articles have been published recently that address novel mechanisms for preeclampsia. These mechanisms all involve circulating factors, a favourite topic for preeclampsia researchers. These factors may interfere with angiogenesis, engage angiotensin (Ang) II signalling, and directly impair endothelial function.
VEGF, PlGF and sFlt1
Vascular endothelial growth factor (VEGF) must be very busy during pregnancy. The growth factors receptor, fms-like tyrosine kinase 1 (Flt1), exists in two forms, namely a membrane-bound receptor tyrosine kinase that transmits angiogenic signals and a soluble secreted ectodomain (sFlt1), which may capture VEGF and keep the growth factor from its active bound receptor.
