## Astrocyte-Microglia Communication Rebalancing via Cytokine Modulation ### Mechanistic Hypothesis Overview The "Astrocyte-Microglia Communication Rebalancing via Cytokine Modulation" hypothesis proposes that the pathological signaling axis between reactive astrocytes and dysregulated microglia in Alzheimer's disease can be therapeutically rebalanced by modulating specific cytokine pathways that mediate their mutual activation. The central mechanistic claim is that astrocytes and microglia en

**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
