**Background and Rationale**
Alzheimer's disease pathogenesis remains critically linked to APOE4-mediated deficiencies in amyloid-beta clearance and lipid metabolism. However, rather than targeting the downstream miR-33/ABCA1 axis directly, this hypothesis focuses on upstream modulation of SREBP-2, the master transcriptional regulator that co-transcribes miR-33. SREBP-2 activation is normally suppressed by adequate cellular cholesterol levels through SCAP/Insig-mediated ER retention. In APOE4 c
**Background and Rationale**
Alzheimer's disease (AD) pathogenesis is intimately linked to apolipoprotein E (APOE) isoform-dependent differences in amyloid-beta (Aβ) clearance and lipid metabolism. The APOE4 allele, present in approximately 25% of the population and 65% of AD patients, confers the highest genetic risk for late-onset AD. Unlike APOE2 and APOE3, APOE4 exhibits significantly reduced lipidation capacity and impaired Aβ clearance efficiency. This stems from structural differences in
