transplant rejection

(redirected from Acute organ rejection)

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. See Graft-versus-host disease, HLA, MHC, Tissue typing.

transplant

1. an organ or tissue taken from the body and grafted into another area of the same individual or another individual.
2. to transfer tissue from one part to another or from one individual to another.
