Hemoglobin and Heme Scavenger Receptors
Antioxidants & Redox Signaling, 2010Heme, the functional group of hemoglobin, myoglobin, and other hemoproteins, is a highly toxic substance when it appears in the extracellular milieu. To circumvent potential harmful effects of heme from hemoproteins released during physiological or pathological cell damage (such as hemolysis and rhabdomyolysis), specific high capacity scavenging ...

Scavenger receptor regulation and atherosclerosis
BioFactors, 2000AbstractAtherosclerosis and its complications, such as coronary heart disease, heart infarction and stroke, are the leading causes of death in the developed world. High blood pressure, diabetes, smoking and a diet high in cholesterol and lipids clearly increase the likelihood of premature atherosclerosis, albeit other factors, such as the individual ...

Macrophage scavenger receptors
Current Opinion in Lipidology, 1994Macrophage scavenger receptors are integral membrane proteins whose ability to bind and degrade modified LDL has implicated them in the process of atherosclerotic foam cell formation. Their ability to bind non-lipoprotein ligands suggests that they participate in other macrophage-associated host defense activities.

Collagenous macrophage scavenger receptors
Current Opinion in Lipidology, 1996Collagen, the most abundant protein in the human body, is a major constituent of extracellular matrix. Among macrophage membrane proteins, type I and II scavenger receptors and MARCO contain a collagenous domain. Analysis of type I and II receptor knockout mice and histochemical studies indicate that these proteins play roles in scavenger, adhesion and

Macrophage scavenger receptors and atherosclerosis
Trends in Cardiovascular Medicine, 1992The fatty streak is the earliest visible atherosclerotic lesion. Microscopically, this lesion consists of a subendothelial collection of macrophage foam cells that are characterized by their content of numerous lipid droplets. Investigations into the mechanisms responsible for foam cell formation have led to the identification of macrophage scavenger ...

Current Opinion in Lipidology, 2004
This review will survey recent findings on the cholesterol transport and scavenger functions of scavenger receptor BI. Although scavenger receptor BI and CD36 bind many of the same ligands, these two receptors have very specific lipid transport functions: CD36 facilitates the uptake of long chain fatty acids and SR-BI mediates the transport of ...

Scavenger-Receptor Targeted Photodynamic Therapy¶
Photochemistry and Photobiology, 2000Covalent conjugation of a photosensitizer to a ligand that specifically recognized and internalized by a cell-surface receptor may be a way of improving the selectivity of photodynamic therapy (PDT). The class A Type-I scavenger receptor of macrophages, which among other ligands recognizes maleylated serum albumin and has a high capacity is a good ...

Scavenger receptors: Implications in atherothrombotic disorders
The International Journal of Biochemistry & Cell Biology, 2011Scavenger receptors are modified lipoprotein binding receptors, expressed on the surface of a variety of cells including endothelial, macrophages and platelets. The most extensively studied class B scavenger receptors comprise of CD36 and SR-BI and have been found to bind to native and modified LDL.

Scavenger receptors in innate immunity
Current Opinion in Immunology, 1996Scavenger receptors are cell-surface proteins expressed by mammalian monocytes and macrophages and by invertebrate hemocytes, among other cell types. They exhibit distinctive ligand-binding properties, recognizing a wide range of ligands that include microbial surface constituents and intact microbes.

Scavenger receptor Bl and cholesterol trafficking
Current Opinion in Lipidology, 1999Scavenger receptor BI (SR-BI) mediates the selective uptake of HDL cholesteryl ester into steroidogenic cells and the liver and is a major determinant of the plasma HDL concentration in the mouse. Recent studies indicate that SR-BI also alters the metabolism of apolipoprotein B-containing particles and influences the development of atherosclerosis in ...
