**Molecular Mechanism and Rationale** The RAB27A-dependent extracellular vesicle engineering approach leverages the sophisticated molecular machinery governing vesicle biogenesis and mitochondrial dynamics to create a revolutionary therapeutic delivery system. RAB27A, a member of the Rab family of small GTPases, serves as a master regulator of exosome secretion through its interaction with the ESCRT (Endosomal Sorting Complex Required for Transport) machinery and specific effector proteins.

**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
