**Background and Rationale** Apolipoprotein E (APOE) genotype represents the strongest genetic risk factor for late-onset Alzheimer's disease, with the APOE4 allele conferring a 3-15 fold increased risk compared to the more common APOE3 variant. While extensive research has focused on APOE's role in amyloid-β clearance and tau pathology, emerging evidence suggests that APOE4's pathogenic effects extend to fundamental alterations in synaptic membrane composition and function. Lipid rafts, specia

**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
