Torn Muscle? Send In The Gut Microbes For Rapid Repair

“Our observations indicate that gut microbes drive the production of a class of regulatory T cells that are constantly exiting the gut and act as sentries that sense damage at distant sites in the body and then act as emissaries to repair that damage,” said study senior author Diane Mathis, professor of immunology in the Blavatnik Institute at HMS. The team cautions that the findings are based on experiments in mice and remain to be replicated in larger animals and in humans. However, the results raise interesting possibilities about harnessing the power of gut microbes to enhance recovery from injury.
