Host microbiota keep the brain healthy

The gut’s microbiome has an impact on the brain’s immune response throughout life, with a possible effect on the course of diseases affecting the brain. Researchers at the University Medical Center Freiburg have uncovered these effects in mice.The function of brain macrophages is controlled by metabolites of gut bacteria, called short-chain fatty acids. Mice without gut bacteria developed stunted microglia. This study highlights the importance of a balanced diet for the prevention of brain diseases and indicates that there may be a link between gut bacteria and the genesis of neurodegenerative diseases. These findings will be published in the renowned journal Nature Neuroscience. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)
