Description de la recherche

Transduction de signaux dans la cellule pancréatique B en réponse au glucose, acides gras et facteurs de croissance.  Régulation de la sécrétion de l’insuline par le glucose.  Étude du mécanisme de la « glucolipotoxicité » et de la décompensation de la cellule ß- dans l’étiologie des diabètes de type 1 et 2.

Research description

Nutrient signaling and the regulation of insulin secretion in the pancreatic B cell.  Control of pancreatic  ß-cell growth and apoptosis by glucose, fatty acids and peptide growth factors.  Study of the mechanism of  ß-cell « glucolipotoxicity » in the etiology of adipogenic type 2 diabetes as well as type 1 diabetes.
