**Background and Rationale** Apolipoprotein E (APOE) represents one of the most significant genetic risk factors for Alzheimer's disease, with the APOE4 allele conferring a 3-fold increased risk in heterozygotes and up to 15-fold in homozygotes compared to the protective APOE2 and neutral APOE3 variants. The APOE protein functions as a critical lipid transport molecule in the central nervous system, facilitating cholesterol and phospholipid redistribution between neurons, astrocytes, and microg

## Molecular Mechanism and Rationale APOE4-Specific Lipidation Enhancement Therapy targets the fundamental molecular deficiency that distinguishes the APOE4 isoform from its neuroprotective counterparts, APOE2 and APOE3. The apolipoprotein E (APOE) protein exists in three major human isoforms, differing by only two amino acids: APOE2 (Cys112, Cys158), APOE3 (Cys112, Arg158), and APOE4 (Arg112, Arg158). These seemingly minor variations have profound structural and functional consequences, partic
