**Molecular Mechanism and Rationale** The transient receptor potential mucolipin 1 (TRPML1) channel, encoded by the MCOLN1 gene, represents a critical nexus in lysosomal calcium homeostasis and membrane trafficking dynamics within neuronal cells. TRPML1 functions as a calcium-permeable, non-selective cation channel localized to late endosomes and lysosomes, where it orchestrates the release of luminal calcium stores in response to phosphatidylinositol 3,5-bisphosphate (PI(3,5)P2) binding and lo

**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
