Exhaustion of pancreatic beta cells in the face of prolonged insulin resistance results in the development of type II diabetes. Ansarullah et al. now describe an inhibitor of beta-cell insulin signalling that, on removal, increases beta-cell mass and improves beta-cell function, with potential as a new way to address beta-cell failure.
