Targeted deletion of endothelial lipase increases HDL particles with anti-inflammatory properties both in vitro and in vivo.

Previous studies have shown that targeted deletion of endothelial lipase (EL) markedly increases the plasma high density lipoprotein cholesterol (HDL-C) level in mice. However, little is known about the functional quality of HDL particles after EL inhibition. Therefore, the present study assessed the functional quality of HDL isolated from EL(-/-) and wild-type (WT) mice.

Role of endothelial lipase in plasma HDL levels in a murine model of hypertriglyceridemia.

Aim: Hypertriglyceridemia is the most common cause of low plasma high-density lipoprotein cholesterol (HDL-C) levels; however, the correlation between high triglyceride (TG) and low HDL-C remains unclear. Endothelial lipase (EL) is a determinant of plasma HDL levels. We investigated the role of EL in HDL metabolism in a murine model of acute hypertriglyceridemia.

Endothelial lipase is increased by inflammation and promotes LDL uptake in macrophages.

Aim: Endothelial lipase (EL) is a member of the lipoprotein lipase family that regulates HDL metabolism. EL is known to act as a bridging molecule for monocytes or lipoproteins in vascular endothelial cells. We investigated the role and regulatory mechanisms of EL expression in macrophages.
