Comparing 2 hypotheses side-by-side
**Molecular Mechanism and Rationale** The SIRT6-NAD+ axis represents a critical regulatory network governing cellular aging, DNA repair, and chromatin homeostasis, with profound implications for neurodegeneration. SIRT6, a member of the sirtuin family of NAD+-dependent deacetylases, functions as a chromatin-associated enzyme that modulates histone acetylation patterns at telomeres and throughout the genome. The molecular mechanism centers on SIRT6's ability to deacetylate histone H3 lysine 9 (H
**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
