University of Virginia School of Medicine researchers have discovered how Lactobacillus, a bacterium found in fermented foods and yogurt, helps the body manage stress and may help prevent depression and anxiety. The findings open the door to new therapies to treat anxiety, depression and other mental health conditions.
The new research from UVA’s Alban Gaultier, PhD, and collaborators is notable because it pinpoints the role of Lactobacillus, separating it out from all the other microorganisms that naturally live in and on our bodies. These organisms are collectively known as the microbiota, and scientists have increasingly sought to target them to battle disease and improve our health. UVA’s new research represents a major step forward in that effort, providing scientists an innovative new approach to understand the role of individual microbes that could facilitate the development of new treatments and cures for a wide variety of diseases, both mental and physical.
“Our discovery illuminates how gut-resident Lactobacillus influences mood disorders, by tuning the immune system,” said Gaultier, of UVA’s Department of Neuroscience, the Center for Brain Immunology and Glia (BIG Center) and the TransUniversity Microbiome Initiative. “Our research could pave the way towards discovering much-needed therapeutics for
anxiety and depression.”
