DPP4 and pancreatitis: The aims of the present study were, therefore, to probe in a mouse model of diet-induced glucose intolerance [44]–[46] the propensity of the GLP-1 receptor agonists- liraglutide and exendin-4- and the DPP4 inhibitor-sitagliptin- to cause signs of pancreatitis, whilst comparing the action of each on weight gain, glucose homeostasis and beta-cell mass.
