Incretins are hormones that are released from the gut into the bloodstream in response to ingestion of food, and they then modulate the insulin secretory response to the products within the nutrients in the food. Likewise, incretin mimetics and incretin effect amplifiers are the two different incretin based treatment strategies developed for the treatment of diabetes. Incretin effect has been defined as postprandial enhancement of insulin secretion by gutderived factors. The worlds economy coughs out billions of dollars annually to diagnose, treat and manage patients with diabetes.

It has been shown that the naturally occurring gut hormones incretins, glucosedependent insulinotropic polypeptide gip and glucagonlike peptide1 glp1 can preserve the morphology and function of pancreatic beta cell. Until now, diabetes treatment cannot restore the reduced function of pancreatic beta cell. In the pancreas in type 2 diabetes, glp1 stimulates the release of insulin from the beta cells by increasing the size and number of beta cells, and restoring first phase insulin secretion that gets in quicker and keeps the glucose from rising after meals. Beta cell dysfunction in type2 diabetes mellitus holds an important role not just on its pathogenesis, but also on the progression of the disease.
Request pdf incretins in obesity and diabetes incretins are hormones secreted from enteroendocrine cells after nutrient intake that stimulate insulin secretion. Because the disease does not affect insulin sensitivity, patients typi cally require small doses of insulin to maintain glucose control. Mcintyre et al stated that there is a factor from the intestine which stimulates insulin secretion as a response on glucose. Their physiology and application in the treatment of diabetes mellitus hale m. Tasyurek human gene and cell therapy center, akdeniz university faculty of medicine, antalya, turkey. Willingness to administer daily subcutaneous injections, take a second diabetes drug after randomization, potentially initiate insulin and intensify insulin therapy if study metabolic goals are not met, perform selfmonitoring of blood glucose. Type 1 diabetes is character ized by a loss of pancreatic. Medicinal chemistry and applications of incretins and dpp. A recent pointcounterpoint narrative, published in diabetes care on the critical analysis of the clinical use of incretinbased therapies, expresses expert opinions. To model ultastructure of the beta cell, the soft xray tomography technique has been successfully applied to ac.
