Starvation signals control intestinal inflammation in mice

Intestinal inflammation in mice can be dampened by giving them a diet restricted in amino acids, the building blocks of proteins, researchers have found. The results were published online by Nature on Wednesday, March 16.

The findings highlight an ancient connection between 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.

The research team, led by Emory Vaccine Center immunologist Bali Pulendran, discovered that mice lacking the amino acid sensor GCN2 are more sensitive to the chemical irritant DSS (dextran sodium sulfate), often used to model colitis in animals. This line of research grew out of the discovery by Pulendran and colleagues that GCN2 is pivotal for induction of immunity to the yellow fever vaccine.

“It is well known that the immune system can detect and respond to pathogens, but these results highlight its capacity to sense and adapt to environmental changes, such as nutritional starvation, which cause cellular stress,” he says.
