The system, that closely mimics the body’s blood sugar control mechanism, combines a blood glucose monitor and insulin pump technology with software that directs administration of insulin and the blood-sugar-raising hormone glucagon. Because any administration of insulin, even by an artificial pancreas, has been associated with the risk of hypoglycemia, the new system not only administers insulin but also incorporates glucagon, a hormone naturally released in non diabetics by the pancreas to raise blood sugar levels.
The study was supported by grants from the Juvenile Diabetes Research Foundation (JDRF), the Wallace H. Coulter Foundation, the Charlton Fund for Innovative Research in Diabetes and the National Center for Research Resources.
