One Microbial Molecule Makes a Big Difference in Immune Reactions

How can trillions of microbes live in our gut without causing a massive immune reaction? Scientists have been researching this question for years, and we are learning more about how the gut microbiome can coexist harmlessly with our immune system, and even benefit our bodies in many ways. New research has identified a molecule that is found on the surface of many bacterial cells, and how this molecule can stimulate a reaction from the immune system, or…
