## 1. Molecular Mechanism and Rationale The fundamental premise underlying astrocyte-mediated neuronal epigenetic rescue centers on the strategic manipulation of histone deacetylase (HDAC) activity through engineered paracrine signaling. HDACs comprise a family of 18 zinc-dependent enzymes divided into four classes (I, IIa, IIb, and IV) that catalyze the removal of acetyl groups from lysine residues on histone proteins. This deacetylation drives chromatin condensation into heterochromatin, gene

**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
