Monocyte-derived macrophages are among the first cells to accumulate in atherosclerotic lesions. Primarily, they appear to scavenge lipids and lipoproteins from fatty streaks, but their long-term presence and accumulation of cholesterol and cholesteryl esters is the hallmark of atherosclerosis. Atherogenesis begins by a perturbation in the endothelium.

Scavenger receptor class B type I (SR-BI) mediates the selective uptake of HDL cholesteryl esters (CEs) and facilitates the efflux of unesterified cholesterol. SR-BI expression in macrophages presumably plays a role in atherosclerosis.

Oxidized low-density lipoprotein inhibits hepatitis C virus cell entry in human hepatoma cells. [PDF]
Cell entry of hepatitis C virus, pseudoparticles (HCVpp) and cell culture grown virus (HCVcc), requires the interaction of viral glycoproteins with CD81 and other as yet unknown cellular factors.

Initiation of hepatitis C virus infection is dependent on cholesterol and cooperativity between CD81 and scavenger receptor B type I. [PDF]
In the past several years, a number of cellular proteins have been identified as candidate entry receptors for hepatitis C virus (HCV) by using surrogate models of HCV infection.

Scavenger receptor BI facilitates the metabolism of VLDL lipoproteins in vivo
Scavenger receptor class B type I (SR-BI) functions as an HDL receptor that promotes the selective uptake of cholesteryl esters (CEs). The physiological role of SR-BI in VLDL metabolism, however, is largely unknown.

Neutralizing Antibody-Resistant Hepatitis C Virus Cell-to-Cell Transmission [PDF]
Hepatitis C virus (HCV) can initiate infection by cell-free particle and cell-cell contact-dependent transmission. In this study we use a novel infectious coculture system to examine these alternative modes of infection.

Macrophage SR-BI regulates LPS-induced pro-inflammatory signaling in mice and isolated macrophages
Scavenger receptor BI (SR-BI), an HDL receptor, plays a key role in reverse cholesterol transport. In mice, disruption of SR-BI results in hypersensitivity to lipopolysaccharide (LPS) and bacteria-induced septic shock due to adrenal insufficiency and ...

Identification of a residue in hepatitis C virus E2 glycoprotein that determines scavenger receptor BI and CD81 receptor dependency and sensitivity to neutralizing antibodies. [PDF]
Hepatitis C virus (HCV) infection is dependent on at least three coreceptors: CD81, scavenger receptor BI (SR-BI), and claudin-1. The mechanism of how these molecules coordinate HCV entry is unknown.

17β-Estradiol promotes the up-regulation of SR-BII in HepG2 cells and in rat livers
The scavenger receptor class B type I (SR-BI) binds to HDL and mediates the selective uptake of cholesterol esters from HDL to cells. SR-BII is an alternatively spliced product of the SR-BI gene that only differs in the C-terminal cytoplasmic domain ...
