## Mechanistic Overview
H6: Epigenetic Reset via APOE4→APOE3 Conversion Reverses Senescence starts from the claim that modulating APOE; HDAC1; EZH2 within the disease context of neurodegeneration can redirect a disease-relevant process.

**Molecular Mechanism and Rationale**
The APOE4 isoform exhibits fundamentally altered structural and functional properties compared to APOE2 and APOE3, creating a cascade of cholesterol trafficking dysfunction that culminates in astrocyte senescence. The critical structural difference lies in the C-terminal domain, where arginine substitution at position 112 (Arg112) creates an intramolecular salt bridge with glutamate at position 109, forcing domain interaction that impairs lipid binding capa
