Abstract

Restoring dystrophin expression in the muscles of patients with Duchenne muscular dystrophy (DMD) may halt or reverse the degenerative wasting and weakness that causes premature death. However, the therapeutic efficacy of an intervention may be limited by the extent of disease progression prior to treatment. In this study, we considered the potential for ameliorating the pathology in a mouse model of advanced-stage muscular dystrophy by systemic administration of recombinant adeno-associated viral (rAAV6) vectors encoding a microdystrophin expression construct. The treatment of 20-month-old mdx mice restored body-wide expression of a dystrophin-based protein in striated musculature. In aged ..
