Gut microbes are well known to contribute to health and disease, but what has been less clear is how the host controls gut microbes. A study now reveals that mice and humans produce small molecules (microRNAs) from their GI tract, which are shed in feces, to regulate the composition of gut microbes and thereby protect against intestinal diseases such as colitis.
