We have demonstrated that a single injection of interleukin (IL)-12 on the day of bone marrow transplantation (BMT) inhibits acute graft-versus-host disease (GVHD) in mice. This effect of IL-12 can be diminished by anti-interferon (IFN)-gamma mAb. To determine the mechanism by which IFN-gamma affects IL-12-mediated GVHD protection, we have compared the effect of IL-12 on GVHD in C57BL/6 wild-ty...
Kinetics of IFN-γ and IL-17 Production by CD4 and CD8 T Cells during Acute Graft-versus-Host Disease
Graft-versus-host disease (GVHD) is a fatal complication that occurs after allogeneic hematopoietic stem cell transplantation. To understand the dynamics of CD4 and CD8 T cell production of IFN-γ and IL-17 during GVHD progression, we established a GVHD model by transplanting T cell-depleted bone marrow (TCD-BM) and purified T cells from B6 mice into irradiated BALB.B, creating an MHC-matched bu...
Myeloid-derived suppressor cells (MDSCs) inhibit T-cell expansion and functions by versatile mechanisms such as nutrient depletion, nitrosylation, or apoptosis. Since graft-versus-host disease (GVHD) is characterized by the expansion of donor-derived T cells destroying recipient tissue, we analyzed whether MDSCs can be used for GVHD prevention in murine allogeneic bone marrow transplantation mo...
Acute graft-versus-host disease (GVHD) is a common complication of allogeneic hematopoietic stem cell transplantation (HSCT). It has been proposed that tumor necrosis factor alpha (TNF-alpha) blockade with infliximab may be an effective treatment for severe (grades III-IV) GVHD. We determined if infliximab use in this high-risk population was associated with an additional increased risk of non-...
Kinetics of bilirubin and liver enzymes is useful for predicting of liver graft-versus-host disease.
Graft-versus-host disease (GVHD) is the most frequent complication after allogeneic hematopoietic cell transplantation. We analyzed the kinetics of bilirubin and liver enzymes in 47 cases with liver GVHD and in 47 cases without GVHD after allogeneic transplantation for various hematological malignancies. The duration of an liver GVHD episode (LGVHD) was defined as the interval from the point wh...
Mesenchymal stromal cells (MSCs) have been reported to have immunomodulatory effects and ameliorate severe graft-versus-host disease (GVHD) after allogeneic stem cell transplantation (SCT). We have conducted a pilot study using human MSCs for the treatment of steroid-resistant GVHD. Between January 2006 and December 2010, 10 patients (7 males and 3 females) with a median age of 37.9 years (rang...
BACKGROUND Proper histomorphological interpretation of intestinal acute graft versus host disease (A-GVHD) associated with allogeneic bone marrow transplantation (BMT) is critical for clinical management. However, studies methodically evaluating different histomorphological features of A-GVHD are rare. METHODS Colonic biopsies from 44 allogeneic BMT patients having biopsy-proven cutaneous A-G...
Graft-versus-host disease (GVHD) is the most common complication of hematopoietic stem cell transplant (HCT). However, our understanding of the molecular pathways that cause this disease remains incomplete, leading to inadequate treatment strategies. To address this, we measured the gene expression profile of nonhuman primate (NHP) T cells during acute GVHD. Utilizing microarray technology, we ...
OBJECTIVE To determine the value of skin biopsies in the management of suspected graft-vs-host disease (GVHD) within 30 days of allogeneic bone marrow transplantation (BMT). DESIGN Retrospective study based on review of a BMT database. SETTING Leukemia/BMT ward of a tertiary care, university teaching hospital. PATIENTS One hundred and eighty-seven consecutive patients who received allogen...
Allogeneic hematopoietic stem cell transplantation (HSCT) is the treatment of choice for high-risk hematological malignancies, yet a major complication associated with this therapy is acute graft-versus-host disease (GVHD). Despite a well-defined pathophysiological mechanism, there are no definitive markers for predicting acute GVHD development or progression to advanced stages. In the current ...
