Scavenger receptor class B type I reduces cholesterol absorption in cultured enterocyte CaCo-2 cells1

Journal of Lipid Research, 2004
Scavenger receptor class B type I (SR-BI) mediates selective uptake of cholesteryl esters from HDL as well as efflux of cellular free cholesterol to HDL. It is unclear whether the receptor is involved in intestinal cholesterol absorption.

Differentiation-dependent expression and localization of the class B type I scavenger receptor in intestine

Journal of Lipid Research, 2001
The current study used the human Caco-2 cell line and mouse intestine to explore the topology of expression of the class B type I scavenger receptor (SR-BI) in intestinal cells.

Scavenger receptor class B, type I-mediated uptake of A1AT by pulmonary endothelial cells.

Am J Physiol Lung Cell Mol Physiol, 2015
In addition to exerting a potent anti-elastase function, α-1 antitrypsin (A1AT) maintains the structural integrity of the lung by inhibiting endothelial inflammation and apoptosis. A main serpin secreted in circulation by hepatocytes, A1AT requires uptake by the endothelium to achieve vasculoprotective effects.

Targeting neuroinflammation in Alzheimer’s disease [PDF]

, 2016
Almost 47 million people suffer from dementia worldwide, with an estimated new case diagnosed every 3.2 seconds. Alzheimer’s disease (AD) accounts for approximately 60%–80% of all dementia cases. Given this evidence, it is clear dementia represents one

ApoE-dependent sterol efflux from macrophages is modulated by scavenger receptor class B type I expression

Journal of Lipid Research, 2002
Macrophages express a number of proteins involved in sterol efflux pathways, including apolipoprotein E (apoE) and scavenger receptor class B type I (SR-BI).

Absence of HDL cholesteryl ester uptake in mice via SR-BI impairs an adequate adrenal glucocorticoid-mediated stress response to fasting

Journal of Lipid Research, 2008
Receptor-mediated cholesterol uptake has been suggested to play a role in maintaining the adrenal intracellular free cholesterol pool and the ability to produce hormones.

Effects of oxidized low density lipoprotein, lipid mediators and statins on vascular cell interactions [PDF]

, 1999
The integrin heterodimer CD11b/CD18 (alpha M beta 2, Mac-1, CR3) expressed on monocytes or polymorphonuclear leukocytes (PMN) is a receptor for iC3b, fibrinogen, heparin, and for intercellular adhesion molecule (ICAM)-1 on endothelium, crucially ...

Extracellular Disulfide Bonds Support Scavenger Receptor Class B Type I-Mediated Cholesterol Transport [PDF]

Biochemistry, 2011
Scavenger receptor class B type I (SR-BI) binds high-density lipoprotein (HDL) and mediates the selective uptake of cholesteryl esters (CE). Although the extracellular domain of SR-BI is critical for function, the structural characteristics of this region remain elusive.

High density lipoprotein metabolism in low density lipoprotein receptor-deficient mice1[S]

Journal of Lipid Research, 2014
The LDL receptor (LDLR) and scavenger receptor class B type I (SR-BI) play physiological roles in LDL and HDL metabolism in vivo. In this study, we explored HDL metabolism in LDLR-deficient mice in comparison with WT littermates.
