**Molecular Mechanism and Rationale** The molecular foundation of this therapeutic hypothesis centers on the intricate relationship between TREK-1 potassium channels (encoded by KCNK2) and aquaporin-4 (AQP4) water channel polarization in astrocytic endfeet. TREK-1 channels are mechanosensitive, two-pore domain potassium channels that play crucial roles in maintaining astrocyte membrane potential and cellular homeostasis. Under physiological conditions, these channels facilitate potassium efflux

**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
