**Background and Rationale** Neurodegeneration is characterized by the progressive loss of specific neuronal populations, leading to devastating diseases such as Parkinson's disease (PD), Huntington's disease, and amyotrophic lateral sclerosis. Traditional therapeutic approaches have focused on symptom management or neuroprotection, but these strategies fail to address the fundamental problem: the irreversible loss of specialized neuronal circuits. Recent advances in epigenetic engineering and

**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
