Abstract

I/R is an important non-specific, antigen independent event, which significantly influences the outcome of transplanted organs. Increasing graft immunogenicity and host alloresponsiveness inflicts additional deleterious effects. Ischemia has also been associated with donor conditions such as brain death and the non-heart-beating donor. As an event surrounding organ procurement, preservation and revascularization occurring early in the transplant process, it initiates a cascade of molecular and cellular events which trigger the release of proinflammatory mediators and attraction of various cell types infiltrating the tissues. This inflammatory event influences both acute functional and structural changes in the organ which contributes to reduced graft survival. Eventually, attenuation of I/R by strategies targeting various mediators and cell populations at different levels of the inflammatory cascade may constitute a means to improve both short and long-term success of solid organ grafts.
