PNAS: From HIV to cancer, IL-37 regulates immune system

A University of Colorado Cancer Center study published in a recent issue of Proceedings of the National Academy of Sciences describes the activity of a recently discovered communication molecule of the body's immune system, Interleukin 37 or IL-37. It has been known to limit inflammation and the current study reports its activity in the adaptive immune system: IL-37 inhibits the ability of the immune system to recognize and target new antigens.
