**Molecular Mechanism and Rationale** The fundamental mechanism underlying this therapeutic approach centers on the precise molecular orchestration of synaptic maintenance through phosphatidylserine (PS) exposure regulation. Under normal physiological conditions, PS is actively maintained on the inner leaflet of the plasma membrane through the action of ATP-dependent aminophospholipid translocases, particularly ATP11C and CDC50A. However, during synaptic stress—whether induced by oxidative dama

**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
