Summary

Apolipoprotein E (APOE) is the primary cholesterol carrier in the brain, essential for lipid transport, neuronal repair, and synaptic maintenance. The APOE gene has three common alleles: APOE2, APOE3, and APOE4. APOE4 is the strongest genetic risk factor for late-onset Alzheimer's disease, increasing risk 3-15 fold depending on copy number. APOE4 impairs amyloid-beta clearance, promotes neuroinflammation, disrupts blood-brain barrier integrity, and reduces cerebrovascular function. APOE2 is protective, enhancing amyloid clearance and reducing tau pathology. Therapeutic strategies include APOE4 structure correctors, gene therapy to convert APOE4 to APOE3, and anti-APOE4 antibodies.
