Dendritic Cells in Patients Following Allogeneic Hematopoietic Stem Cell Transplantation
We plan to investigate prospectively and simultaneously skin and blood DC subtypes, their donor/recipient origin and the correlation of DC reconstitution kinetics with treatment, clinical outcome and incidence of aGvHD in patients undergoing allogeneic hematopoietic stem cell transplantation.
Blood and skin DC reconstitution shall be investigated in patients affected by hematological diseases and receiving HLA-matched, mobilized peripheral blood stem cells from related or unrelated donors. We plan to simultaneously collect and process double biopsies, i.e. from graft versus host disease affected and non-lesional skin of patients at onset of acute graft versus host disease following allogeneic hematopoietic stem cell transplantation. Emigration assay, Chimerism analysis and immunohistochemistry will be performed.

Graft Vs Host Reaction
An immunological attack mounted by a graft against the host because of tissue incompatibility when immunologically competent cells are transplanted to an immunologically incompetent host; the resulting clinical picture is that of GRAFT VS HOST DISEASE.
Host Vs Graft Reaction
The immune responses of a host to a graft. A specific response is GRAFT REJECTION.
The survival of a graft in a host, the factors responsible for the survival and the changes occurring within the graft during growth in the host.
Graft Vs Host Disease
The clinical entity characterized by anorexia, diarrhea, loss of hair, leukopenia, thrombocytopenia, growth retardation, and eventual death brought about by the GRAFT VS HOST REACTION.
Immunized T-lymphocytes which can directly destroy appropriate target cells. These cytotoxic lymphocytes may be generated in vitro in mixed lymphocyte cultures (MLC), in vivo during a graft-versus-host (GVH) reaction, or after immunization with an allograft, tumor cell or virally transformed or chemically modified target cell. The lytic phenomenon is sometimes referred to as cell-mediated lympholysis (CML). These CD8-positive cells are distinct from NATURAL KILLER CELLS and NATURAL KILLER T-CELLS. There are two effector phenotypes: TC1 and TC2.
RATIONALE: Efalizumab may be an effective treatment for graft-versus-host disease of the skin caused by a donor stem cell transplant. PURPOSE: This clinical trial is studying the side eff...
RATIONALE: Cyclosporine may induce graft-versus-host disease and make the body build an immune response that will kill cancer cells. Interleukin-2 and interferon gamma may enhance the effe...
The purpose of this study is to determine whether Extracorporeal Photopheresis with UVADEX (ECP) prior to bone marrow or peripheral blood stem cell transplantation is effective in the prev...
RATIONALE: Beclomethasone combined with prednisone may be an effective treatment for graft-versus-host disease caused by stem cell transplantation. It is not yet known if prednisone is mor...
To compare the effectiveness of Tacrolimus and Rapamycin to Tacrolimus and Methotrexate in the prevention of severe graft-versus-host-disease.
This review presents a summary of the research literature related to the incidence and risk factors for chronic graft-versus-host disease in children following allogeneic hematopoietic stem cell trans...
Background: Donor T lymphocytes are directly responsible for graft versus host disease, thus, molecules important in T cell function may constitute appropriate targets for graft versus host disease th...
Neurological manifestations of chronic graft-versus-host disease after allogeneic haematopoietic stem cell transplantation: report from the Consensus Conference on Clinical Practice in chronic graft-versus-host disease.
A major obstacle of allogeneic haematopoietic stem cell transplantation is graft-versus-host disease, an immune-mediated disorder that affects multiple tissues and organs with varying severity. Neurol...
A joint working group established by the Haemato-oncology subgroup of the British Committee for Standards in Haematology (BCSH) and the British Society for Bone Marrow Transplantation (BSBMT) has revi...
Regulatory T cells (Tregs) effectively ameliorate graft-versus-host disease (GVHD). The mechanisms underlying Treg therapeutic effect on GVHD are not fully elucidated. This study investigates whether...
