Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) is the treatment of choice of hematologic malignancies. Acute graft versus host disease (GvHD) is common after HSCT and directly related to graft versus leukemia effect. Little progress has been done in the treatment of acute...

Abstract
We performed myeloablative bone marrow transplantation from an unrelated donor during the patient's first complete remission. After engraftment, he developed acute graft-versus-host disease involving the gastrointestinal tract on day 32. Steroids and mycophenolate mofetil were initiated from day 39....

Abstract
We show that Rapamycin (Rapa) enhances TGFß-dependent Foxp3 expression and induces a potent suppressor function in naive (CD4+ 25-45RA+) T cells. Rapa/TGFß iTregs are anergic, express CD25 at levels higher than expanded nTregs and few cells secrete IL-2, IFNγ or IL-17 even after PMA and Ionomycin...

Abstract
We evaluated the feasibility of combining RIC regimens with low-dose TBI in de novo MDS. The RIC regimen combined with low-dose TBI in this study consisted of fludarabine (150 mg/m(2)), intravenous busulfan (6.4 mg/kg), and TBI (400 cGy). Antithymocyte globulin was used to overcome HLA mismatching....

Abstract
We observed increased ATP concentrations in the peritoneal fluid after total body irradiation, and during the development of GVHD in mice and in humans. Stimulation of antigen-presenting cells (APCs) with ATP led to increased expression of CD80 and CD86 in vitro and in vivo and actuated a cascade of...

Abstract
We investigated the role of host APCs in the suppression of GVHD by donor Tregs. We found that alloantigen expression by the host APCs is necessary and sufficient for induction of GVHD protection by donor Tregs. This requirement was independent of their effect on the maintenance of Treg numbers and...

Our present studies show that B cells require "nurturing" by CD4 T cells through much of their ontogeny in order to respond to allo-signaling and become autoreactive. The nurturing process does not require antigen-specific cognate interactions between CD4 T cells and B cells. It is mediated by IL-4,...
