Organ preservation during transplantation provides a unique and potentially effective method for the use of viral vectors to attenuate reperfusion injury. Sakaguchi and coworkers have used a liposomal viral vector to target a specific cellular transcription factor, nuclear factorkappa B (NF
B). NF
B is a central mediator in signal transduction pathways for inflammatory and hypoxic stress. Numerous investigators have demonstrated that blocking NF
B favorably modulates ischemiareperfusion injury. Hypothermia and circulatory arrest, both associated with organ preservation, may present a novel opportunity to block this central transcription factor using viral vectors.
There are some difficulties with the use of viral vectors
