Abstract It has been observed that a constriction of the gut microbiome occurs with high fat diet, and likewise decreased diversity is directly correlated more severe graft-versus-host disease (GvHD) following allogeneic hematopoietic stem cell transplantation. Taken together it plausible not only content, but source dietary could influence microbiota GvHD outcome. We sought to address this que...
Objectives Graft-versus-host disease (GVHD) is an important complication of bone marrow transplantation. Recent reports suggest the significance T-cell subsets (Th1, Th17, and cytotoxic CD8+ T cells) as well CD163+ macrophages in development cutaneous GVHD. produce various chemokines to establish immunological microenvironment following stimulation by stromal factors lesional skin. Thus, purpos...
Allogeneic hematopoietic stem cell transplantation is the only curative treatment for many life-threatening diseases. Due to difficulty of finding an HLA-identical donor, from a haploidentical donor has become frequent alternative. This option associated with higher risk graft-versus-host disease (GVHD). In this article, we present current view on pathogenesis, and prevention GVHD report clinic...
the aim of this study was to assess the predictive effect of the ebmt risk score on the outcomes of allogeneic stem cell transplantation in a relatively homogenous group of acute myelogenous leukemia (aml) patients regarding the occurrence of acute and chronic graft versus host disease (gvhd). this historical cohort study included adult patients (≥ 15 years old) with aml (n=363) who received al...
Graft-versus-host disease (GVHD) continues to be a major complication after allogeneic bone marrow transplantation, especially with the increasing use of unrelated and mismatched donors. Recently there has been renewed scientific interest in GVHD because of the increasing appreciation of the complexity of the immune responses seen in GVHD. Two basic aspects of the immune response in GVHD, the i...
Graft-versus-host disease (GVHD) remains the major complication after allogeneic bone marrow transplantation (BMT). The process whereby acute GVHD mediated by alloreactive donor T cells transitions into chronic GVHD, which is characterized by prominent features of auto-immunity, has long been unresolved. In this study, we demonstrate that GVHD-associated autoimmunity and, by extension, chronic ...
Previous experimental studies have shown that acute graft-versus-host disease (GVHD) is associated with two waves of donor CD8(+) T cell expansion. In the current studies, we used in vivo bioluminescent imaging, in vivo BrdU labeling, and three different experimental GVHD systems to show that B7-H1 expression by recipient parenchymal cells controls the second wave of alloreactive donor CD8(+) T...
INTRODUCTION Bone marrow transplantation (BMT) is a treatment option for hematological diseases and immunodeficiency. It is frequently used today. BMT predisposes patients to upper airway infections and its complications, such as rhinosinusitis (RS). Chemotherapy, radiotherapy, viral infections, antibiotic therapy, graft versus host disease (GVHD) are rhinosinusitis predisposing conditions. A...
The aim of this work was to decipher how graft-versus-host disease (GVHD) affects T cell production and homeostasis. In GVHD+ mice, thymic output was decreased fourfold relative to normal mice, but was sufficient to maintain a T cell repertoire with normal diversity in terms of Vbeta usage. Lymphoid hypoplasia in GVHD+ mice was caused mainly by a lessened expansion of the peripheral postthymic ...
Chemokines and chemokine receptors play critical roles in directing the migration of alloreactive donor T cells into graft-vs-host disease (GVHD) target organs. However, blockade of GVHD by antagonist Ab against chemokine receptors remains an elusive goal. Using a mouse model of human GVHD, we demonstrate that in vivo administration of anti-CXCR3 Ab for 21 days (long-term), but not for 7 days (...
