Role of neuromediators in the functioning of the human microbiota: “Business talks” among microorganisms and the microbiota-host dialogue

详细

Current concepts concerning the social behavior of microorganisms inhabiting the human gastrointestinal (GI) tract and their role in the formation of integrated supracellular structures and in intercellular communication in the host–microbiota system are reviewed. The analysis of the literature data and of the results obtained by the authors indicates an important role of neuromediators (biogenic amines, amino acids, peptides, and nitric oxide) in intra- and interspecies microbial communication, as well as in the microbiota–host dialogue. The role of this dialogue for human health, its effect on the human psyche and social behavior, and the possibility of construction of probiotic preparations with a target-oriented neurochemical effect are discussed.
