**Background and Rationale**
Alzheimer's disease pathogenesis involves APOE4-mediated impaired lipidation and reduced amyloid-beta clearance. Rather than targeting miR-33 downstream effectors, this approach directly inhibits SREBP-2 (SREBF2), the master transcriptional regulator that co-transcribes with miR-33. SREBP-2 normally activates cholesterol biosynthesis genes while simultaneously producing miR-33 to prevent excessive cholesterol efflux, creating a tightly coordinated metabolic program.
**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
