Induction of dominant transplantation tolerance by an altered peptide ligand of the male antigen Dby.
T cell reactivity to minor histocompatibility (mH) antigens is responsible for rejection of HLA-matched allografts, limiting the effectiveness of transplantation for the treatment of end-stage organ failure. The deadbox gene Dby is located on the Y chromosome and encodes an mH antigen that prompts rejection of male tissues by female mice. Establishing a network of regulatory T (T(reg)) cells that is capable of coercing naive cells to adopt a tolerant phenotype offers an attractive strategy fo...Expand abstract
