transplantation antigen

The commonly used term for any of the histocompatibility antigens that cause the immune system of one individual to reject transplanted tissue.
See also: antigen


the transfer of living organs and tissue from one part of the body to another or from one individual to another. Transplantation and grafting mean the same thing, though the term grafting is more commonly used to refer to the transfer of skin. See grafting (1).
Occasionally an organ is transplanted from one place to another within the body (autotransplants). Kidneys, for example, have been relocated to enable them to continue functioning after the ureters have been damaged. See also graft rejection.
