Impaired glucose tolerance and insulin sensitivity are established hallmarks of diabetes and it was speculated that also fructose tolerance could be impaired. However, investigation of fructose tolerance has been hampered by the lack of easy accessible pharmacodynamic markers. In humans, the hormone FGF21 has recently been demonstrated to be a sensitive pharmacodynamic marker responding to an oral fructose bolus and exhibiting a divergent secretion pattern in obese diabetic an...

Objective: The exopeptidase dipeptidyl peptidase 4 (Dpp4) selectively cleaves N-terminal dipeptides from several substrates, including cytokines, growth factors, neuropeptides, and the incretin hormones. The systemic inhibition of Dpp4 by the so-called gliptins (oral Dpp4 inhibitors) represents an effective and established treatment option for type 2 diabetes (T2D). In the current study we investigated in healthy as well as in obese and diabetic mice if a liver selective knock...
