## Mechanistic Overview
APOE-Dependent Autophagy Restoration proposes targeting the mechanistic link between apolipoprotein E4 (APOE4) genotype and impaired macroautophagy as a precision therapeutic strategy for Alzheimer's disease. APOE4, carried by ~25% of the population and present in ~65% of AD patients, disrupts autophagosome biogenesis, lysosomal acidification, and autophagic flux through multiple converging mechanisms. Restoring autophagy specifically in APOE4 carriers represents an isof
This hypothesis proposes that mitochondrial dysfunction represents a primary pathogenic mechanism in Alzheimer's disease, operating through impaired ATP synthesis and increased oxidative stress that precedes and drives amyloid-beta accumulation. Specifically, mutations or age-related damage to TFAM (Transcription Factor A, Mitochondrial) lead to defective mitochondrial DNA replication and reduced expression of respiratory chain complexes I and IV. This mitochondrial impairment creates a bioenerg
