Publication Details Neurotensin NT is a 13 amino acid polypeptide first extracted from bovine brain by Carraway and Leeman1. It subsequently was isolated from the human GI tract and found to have the same amino acid sequence2. Neurotensin has a number of interesting pharmacologic effects that include hypotension, tachycardia, and cyanosis 34 and stimulation of secretion from the small intestine 5. It also has been repoed to inhibit the interdigestive myoelectric complex and stimulate insulin release6. NT also increases venous vascular permeability, raises blood glucose, 789and lowers blood pressure14. Ref: Neurotensin is a 13 amino acid peptide produced by the N cells of the ileal mucosa. It stimulates intestinal secretion and motility, and inhibits gastric secretion.
