Gut Bacteria: Immune System Hackers Gut Bacteria: Not Just Hitchhikers, but Immune System Hackers Imagine your gut as a bustling city where trillions of bacteria live side by side with your own cells. For years, scientists believed these microbes mostly played supporting roles—helping digest food and produce vitamins. A new study published this week in Nature Microbiology radically changes that view. A Hidden Communication System Researchers led by Prof. Pascal Falter-Braun at Helmholtz Munich, with first authors Veronika Young and Bushra Dohai, analyzed samples from healthy human intestines. Their international team, spanning institutions such as LMU Munich, Aix Marseille University, and Inserm, uncovered a surprising mechanism at work. Roughly 80% of common gut bacteria from the Pseudomonadota family (formerly known as Proteobacteria) were found to carry type III secretion systems . These are m...
