allogeneic bone marrow transplantation is the only definie cure in thalassemia and its most important complication is chronic graft-versus-host disease (cgvhd). we analysed the incidence of cgvhd and its associated risk factors in a group of 89 iranian thalassemic patients of hla-identical sibling transplants surviving at least 90 days after transplantation.in the majority of cases (39) cgvhd o...

BACKGROUND CD4(+)interferon (IFN)-γ(+) T cell (Th1) and CD4(+)interleukin (IL)-4(+) T cell (Th2) polarizations are crucial in the pathogenesis of graft-versus-host disease (GVHD). However, this hypothesis is largely based on animal experiments of Parent-into-F1 GVHD model. The causal relationship between kinetics of Th1, Th2 and associated cytokines and the clinical activity of GVHD in a real w...

BACKGROUND Graft-versus-host disease (GvHD) is an adverse effect following hematopoietic stem cell transplantation (HSCT) in humans. Dogs represent a key model organism for the development of treatment protocols for HSCT. However, detailed descriptions of canine GvHD and its treatment are rare. Herein we describe the development of canine GvHD and therapeutic intervention. MATERIALS AND METHO...

Abstract Graft versus host disease (GVHD) is a significant cause of morbidity and mortality following hematopoietic stem cell transplantation (HSCT). While donor T cells have been shown to be instrumental in pathogenesis, prior studies are limited, as assumed depleted by conditioning (chemotherapy ± irradiation) used HSCT. Recent data suggest that skin resident memory survive HSCT humans contri...

Mismatch between bone marrow transplant (BMT) patient and donor for an amino acid polymorphism within the adhesion molecule CD31 has recently been reported to increase risk for the development of graft-versus-host disease (GVHD). We further examined this association in a larger series of 301 BMT patients (227 with grade III/IV GVHD and 74 with grade 0 GVHD) and their HLA-identical sibling donor...

Acute and chronic graft-versus-host disease (GVHD) remain the major complications limiting the efficacy of allogeneic hemopoietic stem cell transplantation. Chronic GVHD can evolve from acute GVHD, or in some cases may overlap with acute GVHD, but how acute GVHD evolves to chronic GVHD is unknown. In this study, in a classical CD8+ T cell-dependent mouse model, we found that pathogenic donor CD...

Whether the hematopoietic cell transplantation comorbidity index (HCT-CI) can provide prognostic information about development of acute graft-versus-host disease (GVHD) and subsequent mortality is unknown. Five institutions contributed information on 2985 patients given human leukocyte antigen-matched grafts to address this question. Proportional hazards models were used to estimate the hazards...

• Monoclonal antibody blockade of the common gamma chain attenuates acute and chronic GvHD. • Common gamma chain cytokines increase granzyme B levels in CD8 T cells, which is reduced upon CD132 blockade in vivo. Abstract The common gamma chain (CD132) is a subunit of the interleukin (IL) receptors for IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21. Because levels of several of these cytokines were sh...

Background: Based on the dynamics of antigen recognition from T cell receptor complex and T cell activation, different function of T cells may present different morphology feature, at least at molecular level. Regulatory T (Treg) cells play a critic role in regulation the onset of graft versus host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Little is kn...

Graft-versus-host disease(GVHD) is currently encountered following bone marrow transplantation and transfusion. GVHD associated with transfusion(TA-GVHD) in apparently immunocompetent recipients has been recently reported with increasing frequency. A consistent finding in many of these cases is that the recipient received blood from a donor homozygous for one of the the recipient's HLA haplotyp...
