Product Information

Glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) are important incretin hormones contributing to 50-70% of the stimulation of insulin secretion after a meal.Dipeptidyl-peptidase IV(DPP-4) inhibitors inhibit the degradation of GLP-1 and GIP as well as that of other regulatory peptides.[1] Sitagliptin abolished sDPP-IV effects on splenic CD4+ T-cell migration whereas incretins decreased migration of lymph node, but not splenic, CD4+ T-cells. Sitagliptin decreases migration of splenic CD4+ T-cells through a pathway involving Rac1/VASP, whereas its inhibitory effects on the migration of lymph node CD4+ T-cells involve incretin-activation of the NF-κB pathway.[2]It is eliminated renally, with a terminal half-life of 11.8-14.4 hours.
