**Molecular Mechanism and Rationale** The hypothesis centers on the differential regulation of lipid droplet composition between A1 and A2 astrocyte phenotypes through the enzymatic balance of diacylglycerol O-acyltransferase 1 (DGAT1) and sterol O-acyltransferase 1 (SOAT1). DGAT1 catalyzes the final step in triglyceride synthesis by transferring acyl-CoA to diacylglycerol, while SOAT1 (also known as ACAT1) esterifies cholesterol to form cholesteryl esters. In A2 astrocytes, elevated SOAT1 acti

**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
