Glucagon-like peptide-1 and insulin synergistically activate vagal afferent neurons
Intestinal glucagon-like peptide-1 (GLP-1) and pancreatic insulin, released postprandially, commonly regulate glucose metabolism. Recent clinical experience indicates that the GLP-1R agonist and insulin in combination, compared to insulin alone, results in better glycemic and weight controls in type 2 diabetic patients. These observations suggest possible interactive effect of these hormones. These hormones, in addition to peripherally controlling glycemia, exert central regulation of food intake and glucose metabolism, the effect at least partly mediated by signaling to the brain via the vagal afferents.
