The hypothesis of partial neuronal reprogramming via a modified Yamanaka cocktail represents a paradigm shift in approaching neurodegeneration through epigenetic rejuvenation while preserving neuronal identity. This approach leverages the fundamental principle that cellular aging is largely driven by progressive epigenetic modifications rather than irreversible genetic damage, making it theoretically reversible through controlled reprogramming interventions.

**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
