title = "Enthodelial lipase: structure, functions and role in diseases",
abstract = "Endothelial lipase (EL) is a recent identified member of the lipase gene family. It exhibits a high degree of sequence similarity to lipoprotein lipase (LPL) and hepatic lipase (HL). In contrast to other major human lipases, EL is only synthesized and expressed by the endothelial cells in a variety of different tissues. It displays phospholipase A1 activity, catalyzing primarily on the hydrolysis of high-density lipoprotein (HDL) phospholipids and facilitates the clearance of HDL from the circulation. Research carried out in the past two decades investigated the physiological role of EL in modulating the HDL metabolism. Increased plasma EL concentrations have been found to be associated with a deteriorated lipoprotein-lipid profile. Elevated plasma triacylglycerol, apolipoprotein-B (apoB) concentrations and smaller low density lipoprotein (LDL) particle size were observed in parallel with increasing EL expression. Positive correlation between plasma EL levels and proinflammatory cytokine concentrations including tumor necrosis factoralpha (TNF-A) and interleukin-1 beta ((IL)-1{\ss}) was observed among individuals with metabolic syndrome, suggesting the possible role of EL in the development of cardiovascular disease (CVD). Nevertheless, the effect of EL on human health remains to be a subject of debate and some controversial results were reported in the previous literatures. The present chapter therefore summarizes the recent findings with regard to the molecular structure and biological mechanisms of EL, factors affecting the EL expression and activity as well as its role in some inflammatory disorders.",
