Exploring the new world of neurological probiotics-Probiotics benefits your nervous system

Probiotics are known to promote a healthy gut, often referred to as 'good bacteria', but whether they can promote a healthy mind. Exploring the new world of neurological probiotics, researchers in BioEssay spresent new ideas on how neurochemicals delivered directly to the gut, via probiotic intestinal microbiota, exert their beneficial effects in maintaining gastrointestinal health and even psychological well-being.

The research proposes that through a unifying process of microbial endocrinology, neurochemical-producing probiotics could act as a delivery mechanism for neuroactive compounds that could improve a host's gastrointestinal and psychological health.

Professor Lyte considers the selection of probiotics, such as lactobacilli and bifidobacteria, and how the active uptake of neurochemicals, generated by bacteria in the gut and circulated through a patient's bloodstream, represents a pathway for probiotics to exert extra-intestinal effects including behavioral changes.


Writing in a commentary piece in the same issue of BioEssays Dr Gregor Reid, from the University of Western Ontario, outlines some of the potential clinical implications of this research.

"Until recently the idea that probiotic bacteria administered to the intestine could influence the brain seemed almost surreal," said Reid, "Yet in Lyte's paper the concept is supported by studies showing that microbes can produce and respond to neurochemicals, which can induce neurological and immunological effects on the host."

"The research presents an idea for selecting probiotic strains with neurological applications and linking this with immune-modulatory effects while highlighting the fact that microbial strains already being widely ingested in fermented food can produce neurochemicals," concluded Reid. "Could this mean that adjunct treatment for people suffering from certain types of mental health problems is a fecal transplant? Food for thought."
