Aryl hydrocarbon receptor (AhR), expressed in microglia, astrocytes, and neurons, normally ligates tryptophan catabolites from gut bacteria (indole, indole-3-propionate). Dysbiosis depletes tryptophan-metabolizing commensals, reducing AhR ligand availability. Simultaneously, chronic neuroinflammation elevates IDO1, shunting tryptophan toward kynurenine pathway, producing quinolinic acid (NMDAR agonist) and ROS. SCFAs normally suppress IDO1 via GPR41/GPR43-STAT3 signaling, creating a protective d

Gut dysbiosis depletes butyrate-producing commensals (Faecalibacterium prausnitzii, Clostridium XIVa, Akkermansia muciniphila), reducing SCFA-mediated activation of microglial GPR43/GPR41 receptors and HDAC inhibition. This removes inhibitory checkpoints on NF-κB, permitting unchecked pro-inflammatory cytokine production (TNF-α, IL-1β, IL-6). The pathway integrates receptor-mediated G-protein signaling with epigenetic regulation through histone deacetylase inhibition, creating a dual braking mec
