CD8A and graft versus host disease: In these experiments, GVHD was induced following an MHC-matched (B6, H-2b), female→male (F→M) bone marrow transplantation (BMT) by cotransfer of T cell–depleted bone marrow (TCDBM) and CD8+ MataHari (Mh) T cells transgenic for a T cell receptor (TCR) reactive with male antigen (TCDBM+T) (30).
