Guenther et al. have developed a protease-activatable AAV provector to target diseased tissue microenvironments exhibiting elevated extracellular protease activity. The provector delivers transgenes to high-MMP-activity regions of the damaged heart following a myocardial infarction, with concomitant decreased delivery to many off-target organs, including the liver.
