Exendin controls insulin

Researchers in Philadelphia trialled a peptide called exendin-(9-39) in nine patients aged 15–47 years.

The peptide effectively controlled blood glucose levels during fasting in all nine of the participants.

Exendin also controlled insulin secretion in cell studies of beta cells taken from newborns with hyperinsulinism.

In about half of congenital HI cases, abnormal cells are diffused through the pancreas. Surgeons must remove almost all of the pancreas, leaving patients
