Les mutations de TET2, IDH2 et DNMT3A, 3 gènes impliqués dans la régulation de la méthylation de l'ADN, sont fréquentes dans les lymphomes T périphériques (PTCL), mais leurs conséquences sont mal connues. Nous avons montré que les mutations d'IDH2 dans les lymphomes angioimmunoblastiques (AITL) sont restreintes aux cellules T tumorales et que l'enzyme mutée, exprimée dans des lymphocytes T, produit bien l'oncometabolite D-2 hydroxyglutarate (D-2HG). Utilisant des modèles de souris transgéniques, nous avons montré que, dans un lymphocyte T, seule la mutation IDH2R172K produit suffisamment de D-2HG pour inhiber les protéines TET et altérer la différentiation lymphoïde. Ceci peut expliquer qu'IDH2R172 soit la seule mutation d'IDH retrouvée dan...
