Transplant immunosuppression increases and prolongs transgene expression following adenoviral-mediated transfection of rat lungs

Background: Gene therapy provides the potential to modify donor organs to better withstand transplantation, but this has yet to be realized. In vivo gene transfer using adenoviral vectors has had limited success because of host immune response that induces inflammation and limits the amount and duration of transgene expression. We hypothesize that transplantation immunosuppression can attenuate the post-transfection host-immune response to allow for improved gene transfer following adenoviral-mediated transfection.
