Common molecules made by bacteria in the gut may act as chill pills for the immune system. Molecules secreted by intestinal bacteria work to prevent misplaced immune attacks in inflammatory bowel diseases like colitis, a new study finds.

“It is a huge advance,” says Sarkis Mazmanian of Caltech. “This opens up the notion that a very easy and potentially very safe therapy for inflammatory bowel disease could exist.”

Decades of research have hinted that microbes play a role in immune-related diseases such as obesity, allergy, inflammatory bowel disease and colon cancer. But scientists have had difficulty pinpointing direct links between the bacteria in the gut and the army of immune cells that live there.
