**Molecular Mechanism and Rationale** The therapeutic hypothesis centers on engineering chimeric proteins that combine the mitochondrial cargo-binding specificity of TRAK1 (Trafficking Kinesin Protein 1) with enhanced kinesin heavy chain motor domains, specifically modified KIF5A variants. TRAK1 functions as a critical adaptor protein that links mitochondria to the kinesin-1 motor complex through direct interactions with the mitochondrial outer membrane protein Miro1/2 (mitochondrial Rho GTPase

**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
