## **Molecular Mechanism and Rationale** The molecular foundation of this therapeutic strategy centers on perilipin-2 (PLIN2), a member of the perilipin family of lipid droplet coat proteins that orchestrates the dynamic interface between lipid storage and cellular metabolism. PLIN2 functions as a critical gatekeeper controlling the accessibility of stored triacylglycerols and cholesteryl esters within cytoplasmic lipid droplets. Under physiological conditions, PLIN2 coating prevents premature

**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
