Project description:Donor and recipient lymphocytes mixed reaction and prediction of acute graft-versus-host disease in allogeneic stem cell transplantation
Project description:A protein signature that could identify graft-versus-tumor (GVT) activity without graft-versus-host disease (GVHD), would allow for customized treatment plans following hematopoietic cell transplantation (HCT). Using orthogonal three-dimensional intact-protein analysis system (IPAS)
coupled with protein tagging and novel systems biology pipeline, we identified a signature of 49 proteins that are significantly increased in the plasma of HCT patients who received donor lymphocyte injection for tumor relapse and develop GVT without GVHD.
Project description:This phase II trial studies how well cyclophosphamide works in preventing chronic graft-versus-host disease after allogeneic peripheral blood stem cell transplant in patients with hematological malignancies. Giving chemotherapy and total-body irradiation before transplantation helps stop the growth of cancer cells and prevents the patient’s immune system from rejecting the donor’s stem cells. Healthy stem cells from a donor that are infused into the patient help the patient’s bone marrow make blood cells; red blood cells, white blood cells, and platelets. Sometimes, however, the transplanted donor cells can cause an immune response against the body’s normal cells, which is called graft-versus-host disease (GVHD). Giving cyclophosphamide after transplant may prevent this from happening or may make chronic GVHD less severe.
Project description:RATIONALE: Beclomethasone may be an effective treatment for graft-versus-host disease.
PURPOSE: Phase I/II trial to study the effectiveness of beclomethasone in treating patients who have graft-versus-host disease of the esophagus, stomach, small intestine, or colon.
Project description:To comprehensively investigate the effects of graft-versus-host disease on host metabolism, we carried out RNA-sequencing analysis of bulk liver and epithelial cell fractions of the small and large intestines of bone marrow of mice who received bone marrow (BM) only grafts and mice co-transferred with donor T cells (BMT).
