Comparing 2 hypotheses side-by-side
## Molecular Mechanism and Rationale The mechanosensitive ion channel reprogramming hypothesis centers on the pathological role of PIEZO1 channels in astrocyte phenotype switching during neurodegeneration. PIEZO1, a large trimeric mechanically-activated ion channel, consists of over 2,500 amino acids per subunit and forms a characteristic three-blade propeller structure. In healthy brain tissue, PIEZO1 channels in astrocytes respond to physiological mechanical stimuli by allowing calcium influx
**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
