**Molecular Mechanism and Rationale** The G-protein coupled receptor 32 (GPR32), encoded by the CMKLR1 gene, serves as the primary receptor for resolvin D1 (RvD1), a specialized pro-resolving mediator (SPM) derived from docosahexaenoic acid. In the context of neurodegeneration, GPR32 represents a critical molecular switch that governs microglial transition from inflammatory to resolution phenotypes. Under physiological conditions, RvD1 binding to GPR32 initiates a cascade involving Gα(i/o) prot

**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
