Background
The APOE2 protein is one of three major isoforms (E2, E3, E4) of apolipoprotein E (APOE), a key lipid transport protein involved in cholesterol metabolism and neuronal repair. Encoded by the APOE gene, APOE2 differs from the most common isoform (APOE3) by a cysteine-for-arginine substitution at position 158 (Cys158Arg), altering its structure and receptor-binding affinity. While APOE2 is associated with a reduced risk of late-onset Alzheimer’s disease (AD) compared to APOE4, homozygous carriers may develop type III hyperlipoproteinemia, a lipid disorder. APOE2 exhibits weaker binding to LDL receptors, impairing clearance of triglyceride-rich lipoproteins. Its neuroprotective effects in AD may stem from enhanced amyloid-β clearance and anti-inflammatory properties.
