**Molecular Mechanism and Rationale** The cGAS-STING pathway represents a critical innate immune sensing mechanism that has emerged as a central driver of neuroinflammation in age-related neurodegeneration. In senescent glial cells, particularly microglia and astrocytes, the cellular quality control machinery undergoes progressive deterioration, leading to compromised mitochondrial homeostasis and defective mitophagy. Under normal physiological conditions, the PINK1/Parkin-mediated mitophagy pa

**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
