The role of hepatic lipase in lipoprotein metabolism and atherosclerosis

In addition to its traditional role in the hydrolysis of lipoprotein triglycerides and phospholipids, recent studies have implicated hepatic lipase in other aspects of cellular lipid and/or lipoprotein metabolism and atherosclerosis. Hepatic lipase may serve as a ligand that mediates the interaction of lipoproteins to cell surface receptors and/or proteoglycans as well as modulating aortic lesion development in different animal models. Over the past several years significant advances have been made in our understanding of new, alternative mechanisms by which hepatic lipase may modulate lipoprotein metabolism and the development of atherosclerosis in vivo, Curr Opin Lipidol 9:211-219.
