SR-BI et métabolisme du cholestérol.
médecine/sciences, 1999Dans la classe des recepteurs « eboueurs » (scavenger), le SR-BI (scavenger receptor class B type 1) murin, dont l'homologue humain est CLA1 (CD36 and LIMPII analogous-1), possede la fonction inattendue de lier les HDL, facilitant l'entree selective du cholesterol esterifie des HDL dans la cellule.

SR-BI and cholesterol uptake into steroidogenic cells
Trends in Endocrinology & Metabolism, 2003Scavenger receptor class B, type I (SR-BI) is a receptor for high-density lipoprotein (HDL) that mediates cellular uptake of HDL cholesteryl ester (HDL CE) and is the major route for cholesterol delivery to the steroidogenic pathway. SR-BI is localized in specialized microvillar channels in the plasma membrane that retain HDL and are sites of selective

Scavenger receptor class B type I (SR-BI) was the first molecularly well-defined and functionally active cell surface HDL receptor to be described. SR-BI mediates the transfer of cholesterol from HDL to cells via a mechanism called selective lipid uptake. In vitro and in vivo studies have established that SR-BI is a physiologically relevant lipoprotein

Influence of the HDL receptor SR-BI on atherosclerosis
Current Opinion in Lipidology, 1999The scavenger receptor class B, type I (SR-BI) is an HDL receptor that mediates selective cholesterol uptake from HDL to cells. In rodents, SR-BI has a critical influence on plasma HDL-cholesterol concentration and structure, the delivery of cholesterol to steroidogenic tissues, female fertility, and biliary cholesterol concentration.

The Janus-faced role of SR-BI in atherosclerosis
Nature Metabolism, 2019The entry of remnants of cholesterol-rich lipoproteins, such as low-density lipoprotein (LDL), from the blood stream into the intima of large arteries initiates and then perpetuates atherosclerosis. A study published in Nature sheds new light on this important process by identifying scavenger receptor BI (SR-BI) as a major receptor that mediates LDL ...

Apolipoprotein E (apoE) and the lipoprotein receptor SR-BI play critical roles in lipid and lipoprotein metabolism. We have examined the cholesterol efflux from wild-type (WT) and mutant forms of SR-BI expressed in ldlA-7 cells using reconstituted discoidal particles consisting of apoE, 1-palmitoyl-2-oleoyl-l-phospatidylcholine (POPC), and cholesterol (

Resistivity of liquid SrBi and SrSb alloys
Journal of Non-Crystalline Solids, 1993Abstract Recently, measurements of the electrical resistivity, ϱ, of the liquid SrBi and SrSb systems have been performed as a function of temperature for the entire concentration range. A very high and sharp resistivity maximum occurs at 60 at.% Sr for both systems, indicating that the mixture is semiconducting at this composition. Comparison with

Incommensurate ordering in Ca-Sr-Bi-Cu oxide superconductors
Proceedings, annual meeting, Electron Microscopy Society of America, 1988High temperature superconductivity in non-rare earth ceramic oxides has been recently reported, however the structure and composition of the phase(s) has yet to be unequivocally identified. In the Ca-Sr-Bi-Cu Oxide system onset transition temperatures as high as 120 K have been reported, in both single and multiphase specimens.

ApoA-I-ABCA1 mediated HDL synthesis is major source of plasma preβHDL generation. Lipid free apoA-I is mainly provided from newly synthesized from liver, small intestinal cells and the other hand, apoA-I is also provided from deflated HDL result of transferring cholesterylester into target cells via SR-BI.

Role of SR-BI in regulating lipoprotein structure and metabolism
Drug News & Perspectives, 2001The scavenger receptor class B type I (SR-BI) is a cell surface lipoprotein receptor that mediates physiologically relevant selective cholesteryl ester uptake from high-density lipoprotein (HDL). SR-BI appears to be required for the maintenance of reverse cholesterol transport, normal HDL levels and HDL structure by means of hepatic-selective HDL ...
