**Molecular Mechanism and Rationale** The senescence-associated secretory phenotype (SASP) represents a fundamental shift in microglial function that directly undermines cholinergic neurotransmission through extracellular matrix degradation. Senescent microglia, characterized by elevated p16^INK4A and p21^CIP1 expression alongside telomere shortening, undergo dramatic transcriptional reprogramming driven by NF-κB and C/EBPβ signaling cascades. This reprogramming results in massive upregulation

**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
