reverse cholesterol transport

The modified HDLs are then secreted back into the circulation where they can acquire further cholesterol before returning to the liver. Reverse cholesterol transport ABC-transporter A1 Scavenger receptor class B type I: Abstract: Atherosclerosis is the major cause of death in the Western society due to the development of acute clinical events such as myocardial infarction and cerebral stroke. R01 HL056865/HL/NHLBI NIH HHS/United States, R01 HL129767/HL/NHLBI NIH HHS/United States, NCI CPTC Antibody Characterization Program. Facilitation of reverse cholesterol transport is important for estrogen's potential preventive role. HDL2 is TG-rich, less dense than HDL3, and is protective against atherosclerosis, whereas HDL3 is cholesterol rich and is less protective than HDL2. Get the latest public health information from CDC: https://www.coronavirus.gov, Get the latest research information from NIH: https://www.nih.gov/coronavirus, Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. Cholesterol efflux from macrophages is the first and one of the most critical mechanisms underlying macrophage RCT. ABCA1-expressing cells extrude FC and PL via the interaction of…, NLM Pharmacological attempts to reduce atherosclerotic cardiovascular disease by increasing plasma high-density lipoprotein cholesterol have been disappointing so that recent research has shifted from HDL quantity to HDL quality, that is, functional vs dysfunctional HDL. 1 This landmark discovery inspired investigations into the mechanisms by which HDL confers atheroprotection, leading to the identification of the reverse cholesterol transport (RCT) pathway. From: The HDL Handbook (Third Edition), 2017, Kazuhiro Nakaya, ... Katsunori Ikewaki, in The HDL Handbook (Third Edition), 2017. By contrast, overexpression of ABCA1 into low-density lipoprotein receptor (LDL-R)–/– mice has been shown to protect against development of atherosclerotic plaque by enhancing phospholipid layer and free cholesterol efflux to nascent HDL particles [22]. ApoCIII is an inhibitor of LPL. doi: 10.1371/journal.pntd.0008138. In many tissues, ATP-binding cassette A1 plays a key role in efflux of cholesterol and phospholipids from liver, intestine and macrophages to pre-β-HDL and HDL. HDL particles are heterogeneous. The ABCA1 transporter ensures the efflux of free cholesterol and phospholipids to nonlipidated apolipoproteins allowing genesis of nascent discoidal HDL [14]. In macrophages, fibroblasts, and intestinal cells, GW501516 increases expression of the reverse cholesterol transporter ATP-binding cassette A1 and induces apolipoprotein A1-specific cholesterol efflux. Although bone marrow transplantation studies revealed that macrophage does not represent a predominant source of circulating HDL-C [20], inactivation of ABCA1 in macrophages results in a marked increase in atherosclerotic lesion development [21].

ABCA1-Derived Nascent High-Density Lipoprotein-Apolipoprotein AI and Lipids Metabolically Segregate. The main lipoprotein involved in this process is the HDL-c. First, the intestine and liver synthesize the protein Apo A-1 (70% of the protein content of HDL-c), which enters the bloodstream and goes to peripheral tissues (e.g., heart). RCT from macrophages in atherosclerotic plaques (macrophage RCT) is a critical mechanism of antiatherogenicity of high-density lipoproteins (HDL). The gatekeeper of RCT and HDL generation is an ATP-binding cassette transporter called ABCA1.  |  Nascent HDL particles (Figure 96-1) attract excess free cholesterol from both extrahepatic cells and other circulating lipoproteins. PLoS Negl Trop Dis. In addition to apoA-I, plasma HDLs also contain many other apolipoproteins, including apoC-II and apoE. ABC transporters are defined by the presence of nucleotide-binding domains containing two conserved peptide motifs known as Walker A and Walker B that are present in many proteins that utilize ATP [13]. Etoposide, a DNA topoisomerase II inhibitor as used in cancer chemotherapy, is an inducer of CETP via LXRα [3]. Epub 2017 Oct 26. In human plasma, small discoidal HDL is composed most exclusively of apoA-I, demonstrating that in vivo apoA-I plays a predominant role in stimulating cholesterol efflux via ABCA1 as compared to other apolipoproteins. A Familial Hypercholesterolemia: The Most Frequent Cholesterol Metabolism Disorder Caused Disease. Impairment of RCT due to dysfunctional or reduced HDL has been observed, among others, in the elderly and subjects with CAD, diabetes and Alzheimer's disease (Clee et al., 2000; Singh-Manoux et al., 2008). Liver X receptor (LXR) is known as a strong nuclear factor inducing CETP gene expression. In addition, HDL functions as a chaperone for the transfer of cholesterol ester to the liver. 2018 Nov 1;19(11):3426. doi: 10.3390/ijms19113426. Thus in circumstances leading to lower LDL-C levels, CETP activators may be beneficial for atherosclerosis prevention. Xu B, Gillard BK, Gotto AM Jr, Rosales C, Pownall HJ. Bioloog Arne Dikkers onderzocht de verschillende stappen in dit proces.  |  The final step in plasma HDL metabolism involves the clearance of apo A-I and pre β-1 HDL in the kidney and excretion in the urine. 3) SR-B1 selectively extracts lipids, especially FC and CE, from the mature HDL particle leaving an apo-rich remnant HDL (remHDL) particle and lipid-free apo AI that returns to another RCT cycle. Een beter begrip van reverse cholesterol transport kan waarschijnlijk helpen in de behandeling en de preventie van hart- en vaatziekten. 2019 Jan-Mar;15(1):47-54. doi: 10.14797/mdcj-15-1-47. Efficient reabsorption of transintestinally excreted cholesterol is a strong determinant for cholesterol disposal in mice. Maryse Guerin, in The HDL Handbook (Third Edition), 2017. C. Roger White, ... Geeta Datta, in The HDL Handbook, 2010. Research has provided important insights into the molecular mechanisms of RCT, which facilitate the development of novel therapies based on pharmacologic enhancement of RCT. This site needs JavaScript to work properly. The ABCA-1 transporter protein facilitates the efflux of intracellular cholesterol through an interaction with apo AI on lipid-deplete HDL. As discussed later, the high-CETP adipocyte phenotype may be advantageous for weight reduction on a low-carbohydrate diet. Data from the ERA study [NEJM (2000), 343, 522-529] of 309 women with CAD. Reverse cholesterol transport incorporates HDL metabolism and involves the movement of cholesterol from extrahepatic tissue, including the vessel wall, to the liver for excretion.12 The HDL lipoproteins are the smallest and most dense lipid particles. This chapter discusses therapeutic strategies for augmenting macrophage RCT via improved macrophage cholesterol efflux and cholesterol efflux acceptor functionality of circulating HDL. Reverse cholesterol transport (RCT) is a pivotal pathway involved in the return of excess cholesterol from peripheral tissues to the liver for excretion in the bile and eventually the feces. pre-β-HDL is a nascent, discoid particle that is ApoA-rich and lipid poor.  |  ABCA1-expressing cells extrude FC and PL via the interaction of apo AI with ABCA1 giving nHDL (1). 1 and 2). Keywords: HDL has varying degrees of dysfunction reflected in impaired reverse cholesterol transport (RCT). The response of HDL-C to SSR may be augmented in women with specific ER-α polymorphisms (i.e., IVS1-401 C/C). 2017 Dec;37(12):2260-2270. doi: 10.1161/ATVBAHA.117.310290. Reverse cholesterol transport (RCT) is a pivotal pathway involved in the return of excess cholesterol from peripheral tissues to the liver for excretion in the bile and eventually the feces. ApoE is a high-affinity ligand for binding of CM remnant and IDL to LDL receptor, LRPs, and ApoE receptor. A small fraction of plasma HDL-FC enters the trans-intestinal efflux pathway comprising direct FC transfer to the intestine. 2018 Jul;38(7):1454-1467. doi: 10.1161/ATVBAHA.118.311056. Stroes en prof. dr. S. Middeldorp op 16 september 2011 ATP-binding cassette transporter A1; Atherogenesis; Cholesterol bioavailability; HDL biogenesis; Lipoprotein receptors; Reverse cholesterol transport. Here we describe a simplified version of reverse cholesterol transport, how this has been modified by new research into HDL, and we explain the effect of raising or lowering insulin and insulin sensitivity on RCT. Steiner C, Holleboom AG, Karuna R, Motazacker MM, Kuivenhoven JA, Frikke-Schmidt R, Tybjaerg-Hansen A, Rohrer L, Rentsch KM, Eckardstein Av. These particles can take up more cholesterol via the adenosine triphosphate-binding cassette transporter G1 (ABCG1). The liver and intestine synthesize and secrete nascent discoid HDL, which consists mainly of apo E, apo Cs, phospholipids, and free cholesterol. Ian S. Young, Brona V. Loughrey, in Comprehensive Hypertension, 2007. Human plasma high-density lipoprotein cholesterol concentrations are a negative risk factor for atherosclerosis-linked cardiovascular disease. Elevation of nonfasting triglyceride (TG) levels above 1.8 g/L (2 mmol/L) is associated with increased risk of cardiovascular diseases. Although the impact and significance of this pathway are not completely understood in humans, scavenger receptor class B type I (SR-BI) is the physiologically relevant HDL receptor established in mice. Hij stelde onder andere vast dat de dunne darm mogelijk bijdraagt aan het proces reverse cholesterol transport: door de uitscheiding van cholesterol uit het bloed afkomstig van de levercellen. In addition to RCT, HDL might (1) suppress cytokine-induced adhesion of endothelial cells; (2) protect LDL from oxidation; and (3) have anticoagulant effects (21). Lipid-poor preβ-HDL particles, produced in the liver or the intestine, initiate the efflux of cholesterol and phospholipids from cell membranes via interaction with the adenosine triphosphate-binding cassette transporter A1 (ABCA1). COVID-19 is an emerging, rapidly evolving situation. Metrics of Reverse Cholesterol Transport in Mice and Men. Cholesterol ester is hydrolyzed by cholesterol ester esterase and secreted as biliary cholesterol or utilized to produce steroid hormones. Using apo A-I as a cofactor, LCAT esterifies cholesterol for packaging into HDL, which after remodeling by cholesterol ester transfer protein (CETP) and by endothelial lipase (LIPG) enters hepatocytes via scavenger receptor class B type I (SR-B1) (19). In the plasma, apoA-I activates the enzyme lecithin–cholesterol acyltransferase, which converts discoidal HDL to mature, spherical, cholesteryl ester-rich HDL particles by drawing free cholesterol and phospholipids from IDLs and LDLs until spherical HDL particles are formed with a surface coat of phospholipid, free cholesterol, and apolipoproteins. Differences in prothrombotic factors (fibrinogen, PAI-1, F1.2, and FPA) have also been reported. This indicates that efficient ABCA1-mediated macrophage cholesterol efflux is required to prevent excessive accumulation of cholesterol in macrophages located within the arterial wall and their subsequent transformation into foam cells. Lipid-rich HDLs can enter the hepatocytes through an apoA-I receptor, where it can transfer cholesterol and cholesterol esters to distinct pools within the cell. Atorvastatin and Fenofibrate Increase the Content of Unsaturated Acyl Chains in HDL and Modify In Vivo Kinetics of HDL-Cholesteryl Esters in New Zealand White Rabbits. J Lipid … The scavenger receptor class B1 (SR-B1) modulates the selective uptake of HDL cholesterol ester by hepatocytes. In addition, these lipoproteins also participate in triacylglycerol transport by facilitating the activation of lipoprotein lipase, in the transfer of triacylglycerols between lipoprotein classes, and in the removal of CM remnants and VLDLs enriched in triacylglycerols. The major lipoprotein components in HDL are ApoAI, ApoCII, and ApoE. Plasma concentrations of the HDL3 subclass are more abundant than HDL2 (3:1). Attie AD, Kastelein JP, Hayden MR: Pivotal role of ABCA1 in reverse cholesterol transport influencing HDL levels and susceptibility to atherosclerosis. HDL, high-density lipoprotein; LDL, low-density lipoprotein; TG, triglyceride. USA.gov. HDLs are a complex group of diverse lipoproteins that can contain many different protein constituents and carry out diverse functions related to the return of cholesterol: secretion of cholesterol from the cells, esterification of cholesterol in the plasma, transfer of cholesterol to other lipoproteins, and return of cholesterol from the peripheral tissues to the liver for excretion in the bile. van de Peppel IP, Bertolini A, van Dijk TH, Groen AK, Jonker JW, Verkade HJ. Mechanisms to increase reverse cholesterol transport (RCT) and biliary sterol disposal are currently sought to prevent atherosclerosis. Quantification of dynamic flux through the macrophage RCT pathway, although methodologically challenging, would be immensely valuable to the assessment of HDL metabolism in the setting of pharmacotherapy. Within peripheral cells, ACAT and CEH (Figure 96-1) maintain the balance between free cholesterol and CE (18). Wat is reverse cholesterol transport? 2012 Apr;122(8):385-96. doi: 10.1042/CS20110482. The initial step in reverse cholesterol transport (RCT) is the CE from the cell to acceptor particles through specific transporters. The lypolysis of TG in TG-rich HDL by hepatic lipase and endothelial lipase leads to a smaller HDL which re-enters the RCT cycle. Arterioscler Thromb Vasc Biol. Reverse cholesterol transport is a term that comprises all the different steps in cholesterol metabolism between cholesterol efflux from macrophage foam cells and the final excretion of cholesterol into the feces either as neutral sterols or after metabolic conversion into bile acids (see Figure 1) [5, 10, 11]. In research laboratories, HDL particles can be subfractionated according to size and density by ultracentrifugation and gradient electrophoresis (22). Traditional Model of RCT in the Context of Atheroprotection (Adapted from Glomset and Ross). cholesterol and its fractions, such as reverse cholesterol transport, receptors and transcription factors involved, such as PPARs and their r ole related to exercise, deserve further discussion. Mature HDL can deliver cholesterol to the liver either directly via the scavenger receptor type B1 (SR-B1) or indirectly by exchange of cholesteryl esters to apoB-containing particles for triglycerides (TG). ApoAI is produced in liver and intestine, and is an activator of LCAT and a structural component of HDL and CM. ABCA1 is equally highly expressed in macrophages as well as in atherosclerotic lesions, where it colocalizes with cholesterol-loaded macrophages [19]. SR-BI is an 82-kDa integral membrane protein, belonging to the CD36 family, whose physiologicalrole isrelated totheselective uptake ofHDL cholesteryl ester, the process by which the core cholesteryl ester is taken into the cell without the By continuing you agree to the use of cookies. HDL complexes with SR-B1 and is endocytosed.
