Gut bacteria influence metabolism
Intestinal bacteria linked to obesity

Gut bacteria have an influence on weight gain and obesity, a mouse study shows. This is explained by the activity of a « bacterial sensor » in the intestines that controls gene expression in both the mice and bacteria. In the mice, this involves genes that control metabolism. In the bacteria, these genes regulate food intake, thus leaving more or less nutrients available for the mice. The results imply that treatment of obesity and related illnesses should be possible by manipulating gut bacteria.
