Abstract

Xenotransplantation offers an alternative source of organs to solve the current critical shortage of donor organs required for patients with end-stage kidney, heart and liver disease. For social, ethical and logistical purposes, pigs appear to be the most appropriate donor animal. The immunological barriers to xenotransplantation are greater than in allotransplantation because of the presence of preformed natural antibodies in the serum of the recipient. The rapid binding of antibody to donor endothelial cells is followed by complement activation, cell damage and vascular thrombosis. Antirejection therapies aimed at reducing the level of antibody, complement activity and cell-mediated immuni..
