Effects of Pro-Leu-Gly-NH2 and cyclo (Leu-Gly) on the binding of 3H-quinuclidinyl benzilate to striatal cholinergic muscarinic receptors.

abstract：:The incretin hormones, glucose dependent insulinotropic polypeptide (GIP) and glucagon-like peptide 1 (GLP-1), potentiate insulin secretion and are responsible for the majority of insulin secretion that occurs after a meal. They may also, however, have a fundamental role in pancreatic beta cell development and functio...
