摘要:
Background: Ezetimibe is a potent inhibitor of Niemann-Pick type C1-Like 1 and has been approved for the treatment of hypercholesterolemia. Our preliminary study showed that ezetimibe promotes cholesterol efflux from vascular smooth muscle cells (VSMCs). Our aim was to investigate the cellular mechanisms underlying the ezetimibe actions. Methods and Results: Rat VSMCs were converted to foam cells by incubation with cholesterol:methyl-F-cyclodextrin. The intracellular free cholesterol, total cholesterol, and the ratio of cholesteryl ester to tot...
