Translational aspects of glucagon: current use and future prospects

Abstract

Glucagon is secreted by the pancreatic alpha cell and has long been known to oppose insulin action. A lyophilized form of the hormone has been available to treat episodes of insulin-induced hypoglycemia in insulin-treated people with diabetes for decades, but the difficulty of use was a barrier to widespread utilization. Newer formulations of glucagon are stable at room temperature in single-use devices that many caregivers find are easier to use than the original glucagon emergency kit. In this review , we will review what is known about the role of glucagon in normal physiology and diabetes and then discuss how the research in this area has been translated into treatment for metabolic conditions.
