When a fiber is damaged, the satellite cells (stem cells located near the muscle fibers) are activated and proliferate to allow fiber regeneration ( 2 ).There is currently no treatment for DMD and life expectancy is between 20 to 25 years of age.
Advances in genetic therapeutic strategies for Duchenne
Even if this mutation leads to an absence of the dystrophin in muscles, the development of fibrosis and fat infiltrations in mouse muscles is less important than in DMD muscles ( 8 ).My team has worked for many years to optimise a gene therapy medicine for DMD, and now the quite outstanding work of colleagues in France, in Genethon, in Nantes and in Paris has taken us close to clinical trials in DMD patients.Although clinical trials for skipping exon 51 in. researchers estimate that exon skipping therapy may be.In ex vivo gene therapy in DMD, there is no interest for a transient dystrophin expression.A therapy with herpesvirus is also not possible because of a poor infection of the muscle cells in vivo due to the large size of the virus ( 20, 21 ).Nevertheless, the mdx mouse is a good model and is the most used mouse model to study DMD.The lentiviral vector allowed to obtain the best results with this ex vivo method.
