Gut microbes can stimulate immune cells in mouse brains to fight off viral infections!
Microbe of the episode
Microbe of the episode: Streptoverticillium mobaraense
Nevertheless, microbes in the gut can influence the function of the immune system in the brain, even from a distance. In this study, mice lacking gut microbes did not have as effective an immune response to a virus infecting the brain, and it was found that molecules from bacterial outer membranes were sensed by microglia to activate their defensive response.
