title: The HDL receptor SR-BI: a new therapeutic target for atherosclerosis?
abstract: Although high-density lipoprotein (HDL) metabolism is a crucial process for cholesterol homeostasis and coronary heart disease, therapeutic approaches for selective modification of plasma HDL levels are not currently available. The discovery of well-defined cell-surface HDL receptors should provide new avenues for treatment of atherosclerotic cardiovascular disease. In fact, SR-BI, a recently identified receptor for selective HDL cholesterol uptake, is relevant for physiological processes (for example, HDL metabolism, steroidogenesis and biliary cholesterol secretion) and pathophysiological conditions (for example, atherosclerosis) in animal models. If SR-BI has similar activities in humans, it might represent a new therapeutic target for atherosclerosis.
