In vivo-activated CD103+CD4+ regulatory T cells ameliorate ongoing chronic graft-versus-host disease.
CD103 (alphaEbeta7) has been shown to be an excellent marker for identifying in vivo-activated FoxP3(+)CD4(+) regulatory T (Treg) cells. It is unknown whether reinfusion of in vivo-activated donor-type CD103(+) Treg cells from recipient can ameliorate ongoing chronic graft-versus-host disease (GVHD). Here, we showed that, in a chronic GVHD model of DBA/2 (H-2(d)) donor to BALB/c (H-2(d)) recipi...
متن کاملRegulatory dendritic cells protect against cutaneous chronic graft-versus-host disease mediated through CD4+CD25+Foxp3+ regulatory T cells.
Chronic graft-versus-host disease (cGVHD) is a common cause of morbidity and mortality in allogeneic bone marrow transplantation (alloBMT). However, effective strategies for the treatment of cGVHD have not been established. In this study, we examined the therapeutic utility of modified dendritic cells (DCs) with a greater capacity to regulate immune responses than previously known tolerogenic D...
متن کاملInhibition of graft-versus-host disease by double-negative regulatory T cells.
Pretransplant infusion of lymphocytes that express a single allogeneic MHC class I Ag has been shown to induce tolerance to skin and heart allografts that express the same alloantigens. In this study, we demonstrate that reconstitution of immunoincompetent mice with spleen cells from MHC class I L(d)-mismatched donors does not cause graft-vs-host disease (GVHD). Recipient mice become tolerant t...
متن کاملThe role of host (endogenous) T cells in chronic graft-versus-host autoimmune disease.
Chronic graft-vs-host (cGVH) disease induced by the transfer of Ia-incompatible spleen cells from one normal mouse strain (such as B6.C-H2(bm12)/KhEg (bm12)) to another (such as C57BL/6) causes an autoimmune syndrome resembling systemic lupus erythematosus (SLE). The role of host-derived T cells in this response is not obvious. Previous reports suggested that host T cells might serve to down-re...
متن کاملChronic graft-versus-host disease.
Mr. F is a 62-year-old Caucasian man who was diagnosed with acute myelogenous leukemia (AML) 15 months prior. Following two cycles of induction chemotherapy, his AML was in remission. Four months ago, after a reduced-intensity conditioning regimen, Mr. F received an allogeneic peripheral blood stem cell transplant from his human leukocyte antigen–identical 56year-old sister. Mr. F received a re...
