## Mechanistic Overview
H4: Senomorphic Compounds Preserve Astrocyte Function While Reversing Senescence starts from the claim that modulating MTOR; MEGF10; MERTK within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview H4: Senomorphic Compounds Preserve Astrocyte Function While Reversing Senescence starts from the claim that modulating MTOR; MEGF10; MERTK within the disease context of neurodegeneration can
**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
