In recent years, transplantation immunology has evolved as a distinct field founded on the recognition that rejection of a transplanted organ or tissue is mediated by immune mechanisms in the host responding to antigens in the donor tissue. Included within the scope are T cell immunity; Antigen presentation; Alloreactivity; Pancreas and islet cell transplantation; Allogeneic bone marrow transplantation Models of tolerance induction; Xenotransplantation and The swine leukocyte antigen (SLA) complex. This book gathers the latest research in the exciting new field of transplantation immunology.
