**Background and Rationale** Mitochondrial dysfunction represents a central pathological mechanism across neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis. Neurons are particularly vulnerable to mitochondrial impairment due to their high energy demands and limited regenerative capacity. Traditional therapeutic approaches targeting mitochondrial dysfunction have shown limited success, largely due to challenges in delivering functio

**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
