## Molecular Mechanism and Rationale The integrated stress response (ISR) represents a critical cellular surveillance mechanism that monitors protein folding homeostasis through four upstream kinases: EIF2AK3 (PERK), PKR, GCN2, and HRI. Under proteotoxic stress conditions characteristic of neurodegenerative diseases, PERK undergoes oligomerization and autophosphorylation within the endoplasmic reticulum lumen, subsequently phosphorylating the α-subunit of eukaryotic initiation factor 2 (eIF2α)

**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
