Hematopoietic stem-cell transplantation is an effective buttoxic therapy for a number of life-threatening diseases, especiallyhematologic cancers. The principal complication of allogeneicstem-cell transplantation (the transplantation of grafts fromgenetically different donors) is graft-versus-host disease (GVHD),which can occur despite aggressive immunosuppressive prophylaxisand even when the donor is a "perfectly" matched (HLA-identical)sibling. The complex pathophysiology of GVHD fundamentally dependson interactions between antigen-presenting cells of the recipientand mature T cells of the donor (see Figure). A substantialbody of research in animal models has uncovered the contributionof cytokines to the inflammation and tissue damage . . . [Full Text of this Article]
