TLDR
A pharmacological analysis of the presumed GIP receptor antagonist, (Pro3)GIP, is conducted including interspecies differences between the rodent and human GIP system.
초록
Specific, high potency receptor antagonists are valuable tools when evaluating animal and human physiology. Within the glucose‐dependent, insulinotropic polypeptide (GIP) system, considerable attention has been given to the presumed GIP receptor antagonist, (Pro3)GIP, and its effect in murine studies. We conducted a pharmacological analysis of this ligand including interspecies differences between the rodent and human GIP system.
