transplant rejection

Graft rejection, organ rejection, tissue rejection Immunology The constellation of host immune responses evoked when an allograft tissue is transplanted into a recipient; rejection phenomena may be minimized by optimal matching of MHC antigens and ABO blood groups and ameliorated with immunosuppressants–eg, cyclosporin, tacrolimus, rapamycin Exceptions of TR Corneal transplants, identical twins.
