ATP-binding cassette transporter A1: regulation of cholesterol efflux.
The ATP-binding cassette transporter A1 (ABCA1) is involved in the regulation of cholesterol efflux from cells. Mutations in ABCA1 give rise to familial high-density lipoprotein (HDL) deficiency and Tangier disease, which is characterized by very low levels of HDL in plasma and cholesteryl ester accumulation in tonsils and other reticuloendothelial cells. The mechanism of action of ABCA1 is sti...
متن کاملBilirubin Decreases Macrophage Cholesterol Efflux and ATP‐Binding Cassette Transporter A1 Protein Expression
BACKGROUND Mild but chronically elevated circulating unconjugated bilirubin is associated with reduced total and low-density lipoprotein cholesterol concentration, which is associated with reduced cardiovascular disease risk. We aimed to investigate whether unconjugated bilirubin influences macrophage cholesterol efflux, as a potential mechanism for the altered circulating lipoprotein concentra...
متن کاملThe target of regulating the ATP-binding cassette A1 protein (ABCA1): promoting ABCA1-mediated cholesterol efflux in different cells.
The ATP-binding cassette A1 (ABCA1) transporter plays a major role in the efflux of lipids by mediating the cellular transport of phospholipids and cholesterol to lipid-poor/lipid-free apolipoprotein A-I (apoA-I) particles and thereby exerting important anti-atherogenic effects. Although the mechanism whereby ABCA1 mediates cholesterol efflux is not completely understood, numerous studies have ...
متن کاملATP-binding membrane cassette transporter A1 (ABCA1): a possible link between inflammation and reverse cholesterol transport.
Atherosclerosis is characterized by a chronic inflammatory condition that involves numerous cellular and molecular inflammatory components. A wide array of inflammatory mediators, such as cytokines and proteins produced by macrophages and other cells, play a critical role in the development and progression of the disease. ATP-binding membrane cassette transporter A1 (ABCA1) is crucial for cellu...
متن کاملRegulation and mechanisms of ATP-binding cassette transporter A1-mediated cellular cholesterol efflux.
ATP-binding cassette transporter A1 (ABCA1) plays a major role in cholesterol homeostasis and HDL metabolism. ABCA1 mediates cellular cholesterol and phospholipid efflux to lipid-poor apolipoproteins, and upregulation of ABCA1 activity is antiatherogenic. ApoA-I, the major apolipoprotein component of HDL, promotes ABCA1-mediated cholesterol and phospholipid efflux, probably by directly binding ...
