Both agonism and antagonism of the glucose-dependent insulinotropic polypeptide receptor (GIPR) lead to weight loss in combination with glucagon-like peptide-1 receptor agonists in preclinical models. Here the authors show that this may be explained by desensitization of GIPR activity by chronic GIPR agonism in vitro and in vivo.
