Abstract

Intravascular delivery of adenovirus (Ad) vectors is being developed for liver-directed gene therapy for targeting disseminated disease in cancer therapeutics and for targeting non-hepatic tissues and organs through vector engineering strategies. The utility of Ad vectors is not limited to serotype 5 (Ad5), and many alternate human serotypes and non-human serotypes of Ad are currently being investigated. Critical to intravascular delivery of Ad is the interaction of the virus with host blood cells and plasma proteins, because immediate contact is observed following injection. Although incompletely understood, recent studies suggest that these interactions are critical in dictating the particle bio-distribution and resulting transduction properties of Ad in vivo. For example, plasma proteins—in particular, vitamin K–dependent coagulation zymogens—are able to directly bind to Ad, and "bridge" the virus to receptors in the liver. Unraveling and characterizing these mechanisms will be of fundamental importance both for understanding basic Ad biology in vivo and for refinement and optimization of Ad vectors for human gene therapy.
