**Molecular Mechanism and Rationale** The FOXO3 (Forkhead Box O3) transcription factor represents a pivotal regulatory node in cellular longevity pathways that becomes progressively silenced during neurodegeneration through epigenetic modifications. FOXO3 belongs to the forkhead family of transcription factors and functions as a master regulator of stress resistance, DNA repair, autophagy, and mitochondrial biogenesis—all processes that decline during neurodegenerative disease progression.

**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
