Macrophage scavenger receptor class A: A multifunctional receptor in atherosclerosis.
In atherogenesis, elevated plasma levels of low density lipoprotein (LDL) lead to the chronic presence of LDL in the arterial wall. There, LDL is modified (eg, oxidized), and these modified lipoproteins activate endothelial cells, which attract circulating monocytes. These monocytes enter the vessel wall, differentiate into macrophages, and subject the modified lipoproteins to endocytosis throu...
متن کاملIs the class A macrophage scavenger receptor (SR-A) multifunctional? - The mouse's tale.
The class A macrophage scavenger receptor (SR-A) is the prototypic member of an expanding family of membrane receptors collectively termed scavenger receptors (SRs) (1–3). Receptors of this group recognize a number of ligands, including chemically modified or altered molecules and, in particular, the modified lipoproteins that are pertinent to the development of vascular disease. As shown in Ta...
متن کاملRole for the class A macrophage scavenger receptor in the phagocytosis of apoptotic thymocytes in vitro.
Numerous immature thymocytes undergo apoptosis and are rapidly engulfed by phagocytic thymic macrophages. The macrophage surface receptors involved in apoptotic thymocyte recognition are unknown. We have examined the role of the class A macrophage scavenger receptor (SR-A) in the engulfment of apoptotic thymocytes. Uptake of steroid-treated apoptotic thymocytes by thymic and inflammatory-elicit...
متن کاملClass A scavenger receptor activation inhibits endoplasmic reticulum stress-induced autophagy in macrophage
Macrophage death in advanced atherosclerosis promotes plaque necrosis and destabilization. Involvement of autophagy in bulk degradation of cellular components has been recognized recently as an important mechanism for cell survival under endoplasmic reticulum (ER) stress. We previously found that the engagement of class A scavenger receptor (SR-A) triggered JNK-dependent apoptosis in ER-stresse...
متن کاملCaveolae-dependent endocytosis is required for class A macrophage scavenger receptor-mediated apoptosis in macrophages.
SR-A (class A macrophage scavenger receptor) is a transmembrane receptor that can bind many different ligands, including modified lipoproteins that are relevant to the development of vascular diseases. However, the precise endocytic pathways of SR-A/mediated ligands internalization are not fully characterized. In this study, we show that the SR-A/ligand complex can be endocytosed by both clathr...
