Selective TLR4 Modulation to Prevent Gut-Derived Neuroinflammatory Priming proposes targeting the Toll-like receptor 4 (TLR4) signaling axis as the critical bridge between intestinal barrier dysfunction and CNS neuroinflammation. Chronic low-grade endotoxemia — elevated circulating bacterial lipopolysaccharide (LPS) from a compromised gut barrier — primes microglia into a hyperresponsive state through repeated TLR4 activation, creating a "trained immunity" phenotype that amplifies neuroinflammat

**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
