**Molecular Mechanism and Rationale** The nutrient-sensing epigenetic circuit centered on AMPK-SIRT1-PGC1α becomes progressively silenced in aging neurons through chromatin compaction and histone modifications that restrict transcriptional access. This hypothesis proposes that targeted chromatin remodeling at the SIRT1 locus, rather than direct enzymatic activation, can restore the entire nutrient-sensing cascade by reestablishing permissive chromatin architecture. At the molecular level, agin

**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
