Abstract

Both enzyme replacement and gene therapy of lysosomal storage disorders rely on the receptor-mediated uptake of lysosomal enzymes secreted by cells, and for each lysosomal disorder it is necessary to select the correct cell type for recombinant enzyme production or for targeting gene therapy. For example, for the therapy of Pompe disease, a severe metabolic myopathy and cardiomyopathy caused by deficiency of acid alpha-glucosidase (GAA), skeletal muscle seems an obvious choice as a depot organ for local therapy and for the delivery of the recombinant enzyme into the systemic circulation. Using knockout mice with this disease and transgenes containing cDNA for the human enzyme under muscle or..
