Membrane recruitment of nNOSµ in microdystrophin gene transfer to enhance durability.

Several gene transfer clinical trials are currently ongoing with the common aim of delivering a shortened version of dystrophin, termed a microdystrophin, for the treatment of Duchenne muscular dystrophy (DMD). However, one of the main differences between these trials is the microdystrophin protein produced following treatment. Each gene transfer product is based on different selections of dystrophin domain combinations to assemble microdystrophin transgenes that maintain functional dystrophin domains and fit within the packaging limits of an adeno-associated virus (AAV) vector.
