matched transplants, whereas adoptive transfer of purified wild type T cells to these animals is able to restore allograft rejection (16). In clinical transplantation, therapies that de- plete peripheral leukocytes, including T cells, are effective in preventing and reversing episodes of acute rejection and im- proving long-term graft

In this setting, the transplanted tissue(s) (referred to as the 'graft' – Table 1) is destroyed (rejected) if no further intervention is
Types of Grafts. • Autologous (self). • e.g., BM, peripheral blood stem cells, skin, bone. • Syngeneic (identical twin). • Allogeneic (another human except identical twin). • Xenogeneic (one species to another).

Recipient monocytes are recruited by endothelial cells to the graft tissue. They are also trans- formed to become highly efficient antigen-presenting dendritic
30 Dec 2015 Transplantation is the act of transferring cells, tissues, or organs from one site to another. The malfunction of an organ system can be corrected with transplantation of an organ (eg, kidney, liver, heart, lung, or pancreas) from a donor. However, the immune system remains the most formidable barrier to
First Set Response. ? Skin graft from a genetically unrelated animal of same species. ? Initial acceptance. ? Thrombosed and necrosed. ? Mainly by T lymphocytes an animal has rejected a graft by the first set response, another graft from the same donor is applied – rejected in an accelerated manner. • Mainly by antibodies
The intensity of the immune response against the organ or tissue, also commonly referred to as the graft, will depend on the type of graft being transplanted and the genetic disparity between the donor and recipient. To reduce the possibility of rejection, the donor and recipient are carefully matched for immune compatibility
The student should be able to: • Explain the reason behind phenomenon of graft rejection which occurs between different individuals. • Identify the major antigens that cause the graft rejection (e.g., blood group ags, and HLA (MHC) –ags. • Classify the different types of grafts such as: - Autograft (Autologous antigens).
Ch. Otto, K. Ulrichs: The Immunology of Allograft Rejection. Transplantationsmedizin. 2004, 16. Jahrg., S. 159. 1. Introduction. An understanding of the immunology of transplantation is essential for effec- tive treatment of the recipient's com- plex response to donor tissue. This type of immune response, called rejection,.
