title: [Cellular therapy and gene therapy: perspectives in neuromuscular pathology].
abstract: Identification of the gene coding for the protein (dystrophin) which is lacking or abnormal in Duchenne or Becker type human muscular dystrophies was a decisive turning point in neuro-muscular pathology. Since that time, a considerable number of gene abnormalities have been identified or at least localized. The severity of these diseases, their steady evolution and the absence of any efficient drug therapy, have lead to the development of new therapeutic approaches based on restoring the genetic capacities of the muscle cell. There are two possibilities for therapy. The first is based on the transfer of myogenic cells derived from the 'satellite' cells normally present at the periphery of muscle fibers. The results obtained from a murine model of Duchenne dystrophy ('mdx' mouse) were very promising. However, the results from application of the same techniques to the canine model (GRMDX) or to affected children are, at the present time, disappointing. A number of biological questions remain to be solved before this technique can be more extensively applied to humans. The second possibility is based on gene transfer, through a viral vector. The adenovirus is presently a possible vector. The first experimental results, on 'mdx' mice, are again very encouraging. Extension of these studies to the canine model is a necessary prerequisite for any human application. It should be noted that these two approaches are complementary. Their future applications may depend on the diffuse or selective nature of the skeletal muscle atrophy, and on whether cardiac and respiratory muscles are involved.
