Dysbiosis compromises intestinal tight junctions (occludin, claudin-1, ZO-1) and reduces α-defensin production, permitting Gram-negative bacteria and LPS translocation into systemic circulation. Circulating LPS engages TLR4 on Kupffer cells and bone marrow monocytes, establishing chronic endotoxemia. MyD88-dependent signaling induces CCL2 (MCP-1), recruiting CCR2+ pro-inflammatory monocytes across the compromised blood-brain barrier into CNS parenchyma, where they amplify neurodegeneration.

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
