Abstract:
HDL or apolipoprotein A-Ⅰ,the major protein of HDL particles,protect host against vascular endothelial dysfunction.HDL binding to scavenger receptor-BI activates eNOS for increasing NO.SR-BI and Endothelial lipase(EL) play a critical role in the regulation of plasma HDL.Incubation of HDL with vascular endothelial cells promotes prostacyclin synthesis.Some proteins such as paraoxonase that cotransport with HDL in plasma,have antioxidant properties.HDL inhibits TNF-? dependent expression of adhesion molecules in vascular endothelial cells and interferes with apoptosis,proliferation and migration of vascular endothelial cells.
