Sphingomyelin synthase (SMS) activation for membrane raft remodeling targets the pathological lipid imbalance at synaptic membranes — specifically the shift from sphingomyelin to ceramide — that disrupts synaptic signaling, promotes amyloidogenic processing, and drives neuronal apoptosis in neurodegenerative diseases. **Sphingomyelin-Ceramide Balance at Synapses** Synaptic membranes are organized into specialized lipid raft microdomains enriched in sphingomyelin, cholesterol, and specific gang

**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
