Apolipoprotein E Receptor (ApoE Receptor)

The term "Apolipoprotein E receptor" refers to a group of cell-surface receptors that bind apolipoprotein E (apoE), a key protein involved in lipid metabolism, neuronal maintenance, and neurodegenerative disease processes. These receptors are primarily members of the low-density lipoprotein receptor (LDLR) family and play essential roles in mediating the uptake and cellular effects of apoE-containing lipoproteins. Major receptor types include LDLR, LRP1, VLDLR, ApoER2/LRP8, and Heparan Sulfate Proteoglycans. They are involved in various biological functions such as mediating endocytosis/clearance of triglyceride-rich lipoproteins, regulating cholesterol transport, facilitating cholesterol delivery in the CNS, modulating cellular processes, and influencing susceptibility to neurodegenerative diseases. Dysfunction or altered expression contribute to hyperlipidemias, atherosclerosis, and neurodegenerative disorders including Alzheimer's disease. Recent research highlights potential therapeutic targeting opportunities.
