| graft enhancement, immunologic | The induction of prolonged survival and growth of allografts of either tumours or normal tissues which would ordinarily be rejected. It may be induced passively by introducing graft-specific antibodies from previously immunised donors, which bind to the graft's surface antigens, masking them from recognition by T-cells; or actively by prior immunization of the recipient with graft antigens which evoke specific antibodies and form antigen-antibody complexes which bind to the antigen receptor sites of the T-cells and block their cytotoxic activity.
