Macrophage Scavenger Receptor I (MSR1) Rabbit Polyclonal Antibody

FC, ICC/IF, IHC, WB

Macrophage Scavenger Receptor I (MSR1, also called CD204 or scavenger receptor A) belongs to scavenger receptor A family and represents phagocytic pattern-recognition receptors (PRRs) expressed predominantly on macrophages and dendritic cells. MSR1 is a single-pass type II membrane glycoprotein capable of binding to a wide range of polyanionic ligands (e.g., modified low density lipoproteins, pathogen-derived molecules), and is implicated in the pathologic deposition of cholesterol in arterial walls during atherogenesis, innate immune response as well as Alzheimer's disease. MSR1 mediates the endocytosis of a diverse group of macromolecules including modified LDLs, and scavenger receptors MSR1, CD36 and LOX-1 are three main receptors for oxidized LDL on macrophage membrane wherein MSR1/CD36 account for more than 9/10 of the lipid accumulation in macrophages exposed to oxidized LDL. Defects in MSR1 have also been linked to prostate cancer and Barrett esophagus (BE).
