Die Xenotransplantation, d. h. die Transplantation von tierischen Zellen, Geweben und Organen auf den Menschen, stellt eine vielversprechende Möglichkeit dar, den Mangel an verfügbaren menschlichen Transplantaten zu überbrücken. Aus verschiedenen Gründen werden zur Zeit Schweine als potenzielle Spender von Xenotransplantaten favorisiert. Jedoch ist mit der Verwendung porciner Xenotransplantate das Risiko einer Übertragung von Mikroorganismen auf den humanen Rezipienten verbunden. Dabei geht das größte Risiko von den porcinen endogenen Retroviren (PERVs) aus, die in vielfachen Kopien im Genom aller Schweinerassen integriert sind und die humane Zellen in vitro infizieren. Die PERVs sind mit Retroviren verwand, von denen die meisten Tumore und Immundefizienzen im infizierten Wirt hervorrufen können. Es muss deshalb geprüft werden, ob die Transplantation porciner Organe auf den Menschen eine Übertragung dieser Viren mit sich bringt und damit ein Risiko für den Rezipienten und die Gesellschaft darstellen könnte.
