**Molecular Mechanism and Rationale** Aquaporin-1 (AQP1) represents a critical water channel protein predominantly expressed in the apical membrane of choroid plexus epithelial cells, where it facilitates the bulk water transport necessary for cerebrospinal fluid (CSF) production. The molecular mechanism underlying AQP1-mediated CSF formation involves the coordinated function of multiple transport proteins and ion channels within choroid plexus epithelial cells. AQP1 works in concert with the N

**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
