Desmin-regulated lentiviral vectors for skeletal muscle gene transfer.

ABSTRACT: Lentiviral vectors (LVs) are highly attractive as a gene therapy agent as they are able to stably integrate their genomes in both dividing and nondividing cells and, in principle, provide long-term therapeutic benefit. However, their performance in skeletal muscle in adult animals has, to date, been disappointing. In order to gain clearer insight into their utility in this tissue type, we have conducted an extensive quantitative comparison of constitutive and muscle-specific promoter activities in skeletal muscle and nonmuscle systems following LV delivery in cell lines and neonatal mice. Our data show that LV delivery to hind leg skeletal muscle of neonatal mouse results in long-term transgene expression in adulthood. We find that the human desmin (DES) promoter/enhancer is the first musc
