The success of transplantation in the treatment of human disease has increased the demand for organs and tissues far beyond the available supply. Xenotransplantation - the use of animals as donors - is viewed increasingly as the solution to this problem. This book provides a comprehensive overview of the current state of knowledge of the immunobiology of xenograft rejection and of the many therapeutic options being explored. Authored by the world's leading researchers, the volume is essential reading for anyone interested in the medical, scientific or ethical aspects of xenotransplantation. The book is well illustrated with a large number of tables and figures, and is subdivided into subject areas.
