Induction of donor specific tolerance has been the ultimate goal in organ transplantation.
Recent application of approaches to the induction of allograft tolerance in human kidney transplant
recipients has been based upon preclinical studies in nonhuman primates, including 1) profound T cell
depletion by powerful anti-T cell antibodies, 2) use of total lymphoid irradiation, 3) costimulatory
blockade, 4) infusion of anergic cells 5) donor bone marrow (DBM) infusion without anticipation of
engraftment and 6) DBM transplantation leading to Mixed Chimerism. Mixed Chimerism following
DBM transplantation has to date been the most successful approach for induction of renal allograft
tolerance in clinical kidney transplantation trials.
