# Engineering GPR41-Biased SCFA Analogs to Bypass GPR43-NLRP3 Pro-Aggregation Signaling ## Mechanism of Action Short-chain fatty acids (SCFAs), principally acetate (C2), propionate (C3), and butyrate (C4), are produced by microbial fermentation of dietary fiber in the gut and reach systemic circulation at concentrations in the high micromolar to low millimolar range. These metabolites serve as critical signaling molecules beyond their role as colonic energy substrates, engaging a family of G
**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
