**Molecular Mechanism and Rationale** The apolipoprotein E4 (APOE4) isoform represents the most significant genetic risk factor for late-onset Alzheimer's disease, present in approximately 65% of AD patients despite occurring in only 25% of the general population. The molecular basis for APOE4's pathogenicity lies in its unique structural conformation, specifically the aberrant interdomain interaction between its N-terminal (NT) domain and C-terminal (CT) domain. Unlike the protective APOE2 and

## 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
