**Background and Rationale** Intercellular mitochondrial transfer has emerged as a fundamental mechanism of cellular rescue in the central nervous system, representing a paradigm shift in our understanding of how cells respond to bioenergetic crises. Astrocytes donate functional mitochondria to neurons after ischemic, excitotoxic, or degenerative insults through CD38-dependent extracellular vesicle release and connexin-43-mediated tunneling nanotubes. Mesenchymal stem cells (MSCs) also transfer

**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
