Glucagon-like peptide 1 (GLP-1) is a peptide hormone that is released from the gut after luminal stimulation. The hormone is a potent insulin secretagogue and is a potential novel pharmaceutical adjuvant in the treatment of NIDDM. Insulin is secreted as a series of punctuated secretory bursts superimposed on a basal insulin release. Recently, the contribution of these secretory bursts to overall insulin secretion has been evaluated, and studies...
