Microbiome-Gut-Brain Axis Modulation: New Approaches in Treatment of Neuropsychological and Gastrointestinal Functional Disorders.

The gut-brain axis (GBA) refers to the sophisticated bidirectional communication system connecting the digestive system with the central nervous system. This interaction is enabled by a series of intricate signaling processes, encompassing various neuro-immune and hormonal pathways. The association between the gut microbiome and mental health has garnered immense scientific and public interest, driven by an enhanced understanding of the microbiome's role in facilitating communication between the gut and the brain. This Patent Highlight discloses methods for promoting the colonization of spore-forming bacteria in the gastrointestinal track. These methods include administering a serotonin receptor agonist, such as psilocybin, psilocin, N , N -dimethyltryptamine, bufotenine, 5-methoxy- N , N -dimethyltryptamine, lysergic acid diethylamide, ergine, mescaline, 3,4-methylenedioxyamphetamine, 2,5-dimethoxy-4-methylamphetamine, and others.
