## Selective TFEB Cofactor Enhancement
### Mechanistic Hypothesis Overview
This hypothesis proposes a disease-modifying strategy centered on **Selective TFEB Cofactor Enhancement** as a mechanistic intervention point in neurodegeneration. The core claim is that the biological process represented by selective tfeb cofactor enhancement is not a passive disease byproduct, but a functional bottleneck that shapes how quickly neurons lose homeostasis under chronic stress. In this framing, pathology
**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
