Two main pathophysiological mechanisms are currently involved in Type 2 Diabetes (T2DM), insulin resistance and impairment of beta cell function. However, in recent years a new mechanism was reported: a significant decrease in incretins production and/or action. Incretins are gastrointestinal hormones whose main action is stimulating insulin secretion in response to nutrients. The best known incretins are glucagon like peptide-1 (GLP-1) and Gastric insulinotropic peptide (GIP). GLP-1 and GIP not only increase insulin secretion, but also decrease glucagon secretion, slow gastric emptying and reduce apetite, generating weight loss. Both incretins are rapidly clived by the enzyme dipeptidil peptidase 4 (DPP4). In order to emulate incretins action, several drugs were developed: GLP-1 receptor agonists, GLP-1 mimetics, and DPP4 inhibitors. All of them seem to became a very promising tool for the treatment of T2DM.
