ABSTRACT
Endothelial lipase (EL) is synthetized by endothelial cells and its main substrates are lipoprotein phospholipids. Over expression of EL reduces high density lipoprotein (HDL) cholesterol and phospholipids, in vivo and in vitro. Inhibition of the enzyme achieves the opposite effects. The synthesis of the enzyme is regulated by interleukin 1 and tumor necrosis factor a. These inflammatory cytokines play a role in diabetes and vascular disease. An increase in vascular mechanical forces, that play a role in atherogenesis, also increase the synthesis of EL. There is expression of EL in endothelial cells, macrophages and muscle cells of atherosclerotic lesions of coronary arteries of humans. This evidence leads to the suspicion that EL plays a role in atherogenesis. There are also higher plasma levels of EL in subjects with type 2 diabetes, who are especially susceptible to the development of vascular lesions. Therefore the inhibition of EL could play an important role in HDL metabolism and could be a new therapeutic strategy for the prevention of atherosclerosis.
