  • Title: Preservation, reperfusion, and rejection in transgenic xenograft organs.
    Author: Goddard M, Large SR.
    Journal: J Card Surg; 2000; 15(2):136-40. PubMed ID: 11221972.
    Abstract:
    The success of transplantation has resulted in increasing demand, despite a continuing fall, in donor organ supply. This widening gap encourages the argument for animals to act as a reservoir for donor organs (xenografts). Despite genetic manipulation, transgenic xenograft organs are at risk of vascular rejection in man (delayed xenograft rejection), a process in part involving endothelial cell activation. It appears that ischemia-reperfusion injury also involves endothelial cell activation. Evidence already exists to support the suggestion that ischemia-reperfusion injury may promote delayed xenograft rejection. The mechanisms of both these processes are briefly described and a case is made for optimum organ preservation of transgenic xenograft donor organs before clinical work is proposed.
