Shear stress elevates endothelial cGMP. Role of a potassium channel and G protein coupling.

abstract：BACKGROUND:Phosphatidylserine-expressing microparticles circulate in blood with a short half-life of <10 minutes. We tested the role of an endothelium-derived phosphatidylserine-binding opsonin, developmental endothelial locus-1 (Del-1), in the uptake of platelet microparticles. METHODS AND RESULTS:Cultured human umbi...
