Updated:

The human gut microbiome contains over 100 trillion microorganisms that produce neuroactive compounds, including neurotransmitters like serotonin, GABA, and dopamine. Clinical studies have shown that disruptions in gut bacterial populations correlate with mood disorders, while specific probiotic strains can modulate neurotransmitter levels and influence behavior through the gut-brain axis.

The challenge lies in identifying and delivering viable probiotic strains that can survive gastric conditions while producing therapeutic levels of neuroactive compounds at their site of action.

This page brings together solutions from recent research—including nano-encapsulated GABA-producing probiotics, engineered microorganisms for serotonin production, specific Lactobacillus strains for behavioral disorders, and combination approaches using probiotics with mood-regulating compounds. These and other approaches focus on developing stable formulations that can effectively influence mood and behavior through gut-brain pathways.

1. Recombinant Microorganisms Expressing Enzymes for In Situ Synthesis of Serotonin and Derivatives

DANMARKS TEKNISKE UNIVERSITET, THE TRUSTEES OF COLUMBIA UNIVERSITY IN THE CITY OF NEW YORK, 2023

Using genetically engineered microorganisms to produce and secrete serotonin (5-HT), tryptamine (TRM), 5-hydroxytryptophan (5-HTP), or melatonin for therapeutic use. The recombinant microorganisms are administered to patients with disorders related to serotonin, tryptamine, 5-HTP, or melatonin deficiencies, such as CNS disorders, GI disorders, hormonal imbalances, metabolic diseases, NAFLD, NASH, and diabetes. The microorganisms express enzymes like tryptophan hydroxylase or decarboxylase to synthesize the needed compounds in the patient's gut.

4. Fecal Microbiota Transplantation for Modulating Gut Microbiome in Alcohol Use Disorder Treatment

VIRGINIA COMMONWEALTH UNIVERSITY, 2023

Fecal microbiota transplantation (FMT) as a treatment for alcohol use disorder (AUD) that modulates cognition, behavior, daily function, short-term alcohol craving and alcohol consumption by changing the microbial composition and function in the FMT recipient. The FMT involves transferring fecal material from a donor with a beneficial microbiota profile associated with reduced alcohol craving to a subject with AUD. The FMT is administered rectally as an enema, suppository or oral capsules. The microbiota in the fecal material populate the subject's gut and alter their microbiome to potentially reduce alcohol craving and consumption. FMT for AUD could be a microbial therapy to help treat alcohol addiction.
