MicrobeWorld - Intestinal bacteria produce neurotransmitter (GABA), could play role in inflammation

We identified, to our knowledge, the first bifidobacterial strain, Bifidobacterium dentium, that is capable of secreting large amounts of gamma-aminobutyric acid (GABA). This molecule is a major inhibitory neurotransmitter in the central and enteric nervous systems, says Karina Pokusaeva, a researcher on the study and a member of the laboratory of James Versalovic.
