Overlapping gut microbiota associated metabolites in neurological functions.

Individual gut microbiota metabolites have been associated with single or several neurological functions involving neuronal energy metabolism, blood–brain barrier integrity, neurodevelopment, -inflammation, -transmission, and -protection. Abbreviations: 4-EPS, 4-ethylphenylsulfate; 5-AVA(B), 5-aminovaleric acid(betaine); BBB, blood–brain barrier; GABA, γ-aminobutyric acid; 3M-4-TMAB, 3-methyl-4-(trimethylammonio)butanoate; 4-TMAP, 4-(trimethylammonio)pentanoate; TMA(O), trimethylamine(-N-oxide); TUDCA, tauroursodeoxycholic acid.
