Scientists explain how insulin secreting cells maintain their glucose sensitivity

Scientists at the leading Swedish medical university Karolinska Institutet have now disclosed the mystery how the insulin-secreting cells maintain an appropriate number of ATP sensing ion channel proteins on their surface. This mechanism, which is described in the latest number of Cell Metabolism,...
