The lectin-like oxidized low-density lipoprotein receptor and its role in atherosclerosis

The lectin-like oxidized low-density lipoprotein receptor (LOX-1), a recently identified receptor that plays a role in the uptake of oxidized low-density lipoproteins into endothelial cells, has a pivotal role in the pathogenesis of atherosclerosis. The ways this receptor takes part in atherosclerosis is through uptake of oxidized low-density lipoproteins into endothelial cells, smooth muscle cells, and macrophages; decreasing nitric oxide production; increasing inflammatory cell recruitment; and increasing smooth muscle cell proliferation. LOX-1 is inducible and regulated by multiple factors known to underlie atherogenesis. Further understanding of this receptor may lead to potential molecular targets for prevention and treatment of atherosclerosis.
