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 isoform-targeted approach tha

**SASP-Mediated Complement Cascade Amplification in Alzheimer's Disease** **Overview: Senescence, Inflammation, and Synaptic Loss** Cellular senescence—a state of irreversible growth arrest accompanied by a pro-inflammatory secretome—accumulates dramatically with age and in Alzheimer's disease. Senescent astrocytes and microglia secrete the senescence-associated secretory phenotype (SASP), a cocktail of cytokines, chemokines, proteases, and critically, complement cascade initiators including C
