Plasma GFAP and YKL-40 as companion biomarkers for ABCA7-targeted therapy dosing. Given that V1613M shows complex effects on lipid metabolism, therapeutic ABCA7 modulation requires biomarker-guided dosing to ensure efficacy while monitoring for potential cholesterol dysregulation side effects.

**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
