**Molecular Mechanism and Rationale** The axonal RNA transport reconstitution hypothesis centers on the critical role of heterogeneous nuclear ribonucleoprotein A2/B1 (HNRNPA2B1) in facilitating kinesin-mediated transport of RNA granules along microtubules in neuronal axons. HNRNPA2B1 functions as a key RNA-binding protein that recognizes specific trafficking signals, particularly the A2 response element (A2RE) sequences found in mRNAs destined for axonal and synaptic localization.

**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
