  • Secondly, we describe a complete study protocol (GLUSENTIC) according to which the glucagon sensitivity test will be applied in a cross-sectional study currently taking place. (regionh.dk)
  • Developing a glucagon sensitivity test and index may provide insight into the physiological and pathophysiological mechanism of glucagon action and glucagon-based therapies. (regionh.dk)

  • Glucagon-like peptide-1 (GLP-1) is a hormone consisting of 30 amino acids. (wikipedia.org)
  • Its amino acid sequence, based on GIP, is engineered to bind both GIP and GLP-1 receptors, with modifications to boost its half-life by reducing its susceptibility to proteases and improving its binding to albumin. (asbmb.org)
  • They then built a structural model of the receptor with glucagon bound to it in order to predict how the hormone and receptor interact. (nih.gov)
  • The team is now working to determine the exact structure of the receptor when glucagon is bound to it. (nih.gov)
