Butyrate acts as a pan-HDAC inhibitor suppressing microglial HDAC3 activity. In dysbiosis, butyrate deficiency permits HDAC3 to deacetylate histones at the TREM2 promoter, downregulating TREM2 expression. This exacerbates the TREM2 loss-of-function AD risk phenotype (rs75932628), leading to impaired phagocytosis of Aβ/α-synuclein and metabolic microglial dysfunction (enhanced glycolysis, mitochondrial fragmentation). Undegraded aggregates further stimulate TLR pathways, completing a feedforward

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
