High-density lipoproteins and endothelial function.
Elevated plasma levels of HDL cholesterol or apolipoprotein A-I, the major protein moiety of HDL particles, are protective against coronary artery disease. HDL particles remove cholesterol from peripheral cells and transfer it to the liver for bile acid synthesis. The interaction between lipoproteins is not mediated through simple contact between 2 phospholipid membranes but involves specific p...
متن کاملSynthesis, transport, and processing of apolipoproteins of high density lipoproteins.
Cell biology methods have greatly influenced the elucidation of the biosynthetic pathways of apolipoproteins. In vitro and tissue culture systems allow the study, to a large extent, of the process of synthesis, intracellular processing, secretion, and extracellular processing of the major high density lipoprotein apoproteins apoA-I and A-II and also of a minor component, apoA-IV. Whereas the la...
متن کاملAcrolein Impairs the Cholesterol Transport Functions of High Density Lipoproteins
High density lipoproteins (HDL) are considered athero-protective, primarily due to their role in reverse cholesterol transport, where they transport cholesterol from peripheral tissues to the liver for excretion. The current study was designed to determine the impact of HDL modification by acrolein, a highly reactive aldehyde found in high abundance in cigarette smoke, on the cholesterol transp...
متن کاملEndothelial protection by high-density lipoproteins: from bench to bedside.
There are several potential mechanisms by which HDLs protect against the development of vascular disease. One relates to the unique ability of these lipoproteins to remove cholesterol from the arterial wall. Another is the ability of HDL to prevent and eventually correct endothelial dysfunction, a key variable in the pathogenesis of atherosclerosis and its complications. HDLs help maintain endo...
متن کاملHigh-density lipoproteins reduce endothelial-to-mesenchymal transition.
OBJECTIVE Endothelial-to-mesenchymal transition is an inflammation-induced process by which endothelial cells can transdifferentiate into fibroblasts. Based on the endothelial-protective and antifibrotic effects of high-density lipoproteins (HDL), we aimed to investigate whether HDL can reduce endothelial-to-mesenchymal transition. APPROACH AND RESULTS Therefore, human aortic endothelial cell...
