Macrophage scavenger receptors (MSR) are membrane glycoproteins that mediate the recognition and uptake of a wide variety of negatively charged macromolecules. There are two types of these receptors that differ in the C-terminal region. MSR has a key role in scavenging a variety of macromolecules, including modified lipoproteins, advanced glycation end (AGEs) products and amyloid b-protein (Abeta). While the normal role of MSR is associated with cell adhesion and host defense mechanisms, it also has been implicated in the development of atherosclerosis and Ab deposition in Alzheimer's disease (AD).The observation that the 4 allele of the apolipoprotein E gene is associated with an increased risk for AD has lead to the investigation of lipoprotein metabolism in the brain of AD patients. The type I MSR has been found to be expressed on microglia and Mato cells, but not astrocytes or neurons. In AD brain, MSR type I is strongly expressed by microglia cells that are associated with senile plaques. Because the senile plaques contain AGEs, which are a source of free radicals that could result in oxidative damage to the brain, MSR may have a role in mediating the endocytosis of AGEs.
