WebFor example, LXR activation by cholesterol derivatives (such as oxysterols) or by desmosterol (a molecule similar to cholesterol) 48, promotes macrophage cholesterol efflux via ABCA1 and ABCG1 and also has anti-inflammatory actions 49. Thus, synthetic LXR agonists have been actively investigated for the treatment of atherosclerosis. WebAtherosclerosis (AS) is a common cardiovascular disease and remains the leading cause of death in the world. It is generally believed that the deposition of foam cells in the arterial wall is the main cause of AS. Moreover, promoting cholesterol efflux and enhancing the ability of reverse cholesterol transport (RCT) can effectively inhibit the formation of foam cells, …

WebABCA1 is necessary for the transport of cholesterol and phospholipids to apolipoprotein -I and the biosynthesis of HDL; while ABCG1 mainly promotes the efflux of cholesterol to HDL (Wang and Westerterp, 2024).
