Escolà-Gil JC, Rotllan N, Julve J, Blanco-Vaca F. Atherosclerosis. High‐density lipoprotein (HDL) plays an important protective role against atherosclerosis, and the anti‐atherogenic properties of HDL include the promotion of cellular cholesterol efflux and reverse cholesterol transport (RCT), as well as antioxidant, anti‐inflammatory and anticoagulant effects. See this image and copyright information in PMC. HDL is believed to play a key role in the process of reverse cholesterol transport (RCT), in which it promotes the efflux of excess cholesterol from peripheral tissues and returns it to the liver for biliary excretion.

Epub 2009 Jan 19. Ann Epidemiol. Int J Mol Sci. Clipboard, Search History, and several other advanced features are temporarily unavailable. HDL particles are heterogeneous; they differ in proportion of proteins and lipids, size, shape, and charge. It competes with plasminogen by binding sites, reducing the plasmin generation and inhibiting fibrinolysis, therefore, the thrombus form… Reverse cholesterol transport is facilitated by high-density lipoprotein (HDL) metabolism. The metabolism of high-density lipoproteins (HDL), which are inversely related to risk of atherosclerotic cardiovascular disease, involves a complex interplay of factors regulating HDL synthesis, intravascular remodeling, and catabolism. Targeting high-density lipoproteins: update on a promising therapy. This review describes abnormalities in HDL metabolism and reverse cholesterol transport, i.e. Mokkala K, Juhila J, Houttu N, Sorsa T, Laitinen K. Heliyon. Biochimie.

Potential Link Between Proprotein Convertase Subtilisin/Kexin Type 9 and Alzheimer's Disease. Reverse cholesterol transport is a multi-step process resulting in the net movement of cholesterol from peripheral tissues back to the liver first via entering the lymphatic system, then the bloodstream. Reverse cholesterol transport (RCT) is the process of cholesterol movement from the extrahepatic tissues back to the liver. Proc Natl Acad Sci U S A. -. M01 RR00040/RR/NCRR NIH HHS/United States. Regulation of cholesterol levels is a complicated process, involving cholesterol uptake, biosynthesis, transport, metabolism, and secretion, and has been well described in several recent reviews. First, via interactions of HDL with hepatocyte scavenger receptor class B ( SR-BI ), cholesterol is selectively taken up by the liver. Lipoproteins containing apoA-I [high- density lipoprotein (HDL)] are key mediators in RCT, whereas non-high-density lipoproteins (non-HDL, lipoproteins containing apoB) are involved in the lipid delivery pathway.

Verdier C, Martinez LO, Ferrières J, Elbaz M, Genoux A, Perret B. Arch Cardiovasc Dis. Furthermore, although efflux of cholesterol from macrophages represents only a tiny fraction of overall cellular cholesterol efflux, it is the most important with regard to atherosclerosis, suggesting that it be specifically termed macrophage RCT. Nuclear receptors of the RXR heterodimer family have recently been shown to regulate key genes involved in HDL metabolism and reverse cholesterol transport.

LCAT-mediated esterification of cholesterol and remodeling of HDL particles, 3. direct pathway of HDL cholesterol delivery to the liver, and 4. indirect pathway of HDL cholesterol delivery to the liver via CETP-mediated transfer There are several established strategies for raising HDL cholesterol in humans, such as lifestyle changes; use of drugs including fibrates, statins, and niacin; and new therapeutic approaches. Furthermore, thermogenic stimulation promotes HDL-cholesterol clearance and increases macrophage-to-faeces reverse cholesterol transport in mice. 1978;47:751–7. The science behind the GOOD and BAD cholesterol. The therapeutic approaches include CETP inhibition, peroxisome proliferator-activated receptor (PPAR) agonists, synthetic farnesoid X receptor agonists, and gene therapy. In this video, I have explained HDL synthesis as a nascent HDL and maturation of HDL. HDL is believed to play a key role in the process of reverse cholesterol transport (RCT), in which it promotes the efflux of excess cholesterol from peripheral tissues and returns it to the liver for biliary excretion.

The first theme is that HDL is a universal plasma acceptor lipoprotein for cholesterol efflux from not only peripheral tissues but also hepatocytes, which are a major source of cholesterol efflux to HDL. Front Physiol. One area of agreement is that reverse cholesterol transport remains a primary hypothesis for an anti-atherogenic role of HDL.
