A collaboration involving three laboratories supported by the AFM-Telethon, Atlantic Gene Therapies (AFM-Telethon, Inserm UMR 1089, Université de Nantes, Nantes University Hospital), Généthon (Evry) and the Institute of Myology (Paris), demonstrated the effectiveness of an innovative gene therapy treatment in the canine model of Duchenne muscular dystrophy. This work, published in the journal Molecular Therapy in November, was mainly financed by French Telethon donations. It paves the way for a clinical trial in humans.
