Selective Microglial Reprogramming via Engineered Probiotic Metabolites
🧪 Overview
Genetically engineered probiotics producing specific short-chain fatty acids like butyrate and propionate can selectively reprogram microglial activation from pro-inflammatory M1 to neuroprotective M2 phenotype, reducing Aβ-induced neuroinflammation while enhancing microglial clearance of amyloid plaques.
Debate provenance: derived from debate `sess_gut-brain-ad` on question: Gut-Brain Axis Therapeutics for Alzheimer's Disease?. Consensus signal: domain_expert, skeptic, synthesizer, theorist discussed the mechanism terms Engineered, Metabolites, Microglial, Probiotic, Reprogramming, Selective, TREM2, activation. Novelty signal: skeptic-discussed-with-qualified-concession.
