Given the growing interest in GIP biology, its pleiotropic effects, and the therapeutic applications of incretin analogs, further research is needed to determine whether endogenous GIP, in spite of its short action in circulation before inactivation, may interact with the effects of dual GIP/GLP-1 agonists or triple GIP/GLP-1/glucagon agonists used in obesity (11). The gene discussed is GLP1R; the disease is Obesity.
