Does endothelial alpha-1-antitrypsin attenuate cigarette smoke induced apoptosis in vitro?
Our results suggest that AAT is taken up by endothelial cells via two mechanisms and that intracellular AAT may have a protective role in CS-induced endothelial apoptosis. This may open new insights into the field of endothelial serpins as agents capable of protecting the vasculature from environment-derived noxious substances.
Microparticles from preeclamptic patients activate endothelial cells in the presence of monocytes. Whether all MP have the same effect on monocytes and endothelial cells or only a specific subgroup is the focus of future research.
