## Molecular Mechanism Senescent astrocytes and neurons release senescence-associated secretory phenotype (SASP) factors, particularly IL-1β, TNF-α, and lactate, which bind to microglial receptors including IL-1R, TNFR1, and monocarboxylate transporters. This binding activates NF-κB and mTORC1 signaling pathways, leading to transcriptional upregulation of key glycolytic enzymes hexokinase 2 (HK2) and 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3). HK2 associates with mitochondri
**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

Based on the knowledge gap about senolytics targeting p16/p21+ senescent astrocytes and microglia to reduce SASP-driven neuroinflammation, here are 7 novel therapeutic hypotheses: ## Hypothesis 1: Du...
**Falsification experiments:** - Measure p16/p21 expression patterns over 24-hour cycles in senescent vs. non-senescent brain cells - Test whether circadian-disrupted animals show different senolytic ...
I'll assess the practical feasibility of these senolytic hypotheses from a drug development perspective, focusing on druggability, existing compounds, competitive landscape, safety, and development ti...
