RESUMEN
En los últimos años se reconoce un nuevo mecanismo involucrado en la fisiopatología de la Diabetes Mellitus tipo 2 el déficit de producción y/o acción de las incretinas. Las incretinas son enterohormonas que estimulan la secreción de insulina en respuesta a la ingesta de nutrientes. Glucagon like peptide-1 (GLP1) y Polipéptido insulinotrópico glucosa dependiente (GIP) son las principales incretinas descubiertas hasta hoy. Ambas presentan también efecto trófico sobre las células beta de los islotes pancreáticos. GLP-1 presenta otras acciones como son la inhibición de la secreción de glucagón, enlentecimiento del vaciamiento gástrico e inhibición del apetito. Ambas incretinas son rápidamente clivadas por la enzima dipeptidil peptidasa 4 (DPP-4). Nuevas drogas como los incretinomiméticos, análogos y los inhibidores de DPP-4 se presentan como una terapéutica prometedora para los pacientes con diabetes tipo 2.

ABSTRACT
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.
