**Molecular Mechanism and Rationale** The lysosomal positioning dynamics hypothesis centers on the critical role of LAMP1 (Lysosomal-Associated Membrane Protein 1) in orchestrating the subcellular distribution of lysosomes through its interaction with the dynein motor complex. LAMP1, a heavily glycosylated type I transmembrane protein, serves as more than just a structural component of lysosomal membranes—it functions as a key regulatory hub for lysosomal motility and positioning within neurons

**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
