Intestinal inflammation in mice can be dampened by subjecting them briefly to a diet restricted in amino acids. The findings, made by Bali Pulendran and colleagues at Emory University, highlight an ancient connection between cellular mechanisms to sense nutrient availability and control of inflammation. They also suggest that a low protein diet – or drugs that mimic its effects on immune cells – could be tools for the treatment of inflammatory bowel diseases, such as Crohn’s disease or ulcerative colitis.

This protective effect was shown to be mediated by molecule GCN2, wh...
