Stefan Kiechl and colleagues show that blockade of receptor activator of nuclear factor-κB (RANKL) signaling in hepatocytes by cell type–specific genetic deletion of its receptor promotes greater insulin sensitivity in both a genetic and a nutritional model of type 2 diabetes. They also show epidemiological evidence that elevated serum concentrations of soluble RANKL are a risk factor for the development of this disease.
