Tau-independent microtubule stabilization via MAP6 (also known as STOP protein — Stable Tubule Only Polypeptide) enhancement proposes compensating for tau loss-of-function by upregulating an alternative microtubule-stabilizing protein. This strategy addresses a critical but underappreciated aspect of tauopathies: while pathological tau aggregation receives therapeutic attention, the loss of tau's normal microtubule-stabilizing function equally contributes to neurodegeneration through cytoskeleta

**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
