The synergy is most pronounced under conditions of high somatostatin tone, where neither pathway alone is fully effective but the combination overcomes the inhibitory brake
Notably, GLP-1 directly interacts with vagal afferent neurons 19 , and surgical or chemical denervation of vagal afferents and specific Glp1r knockdown in vagal afferent neurons attenuate anorexigenic, insulinotropic and glycemic effects of exogenous GLP-1 and dipeptidyl peptide-4 (DPP-4
