Glutamine protects mice from acute graft-versus-host disease (aGVHD)
Despite current immunosuppressive therapies, acute graft-versus-host disease (aGVHD) is a major cause of morbidity and mortality in allogeneic hematopoietic stem cell transplantation (HSCT). In the present study, therapeutic effects of intraperitoneal glutamine (Gin) administration (1 g/kg/day) in a mouse aGVHD model were evaluated. Gln administration significantly inhibited the GVHD-induced inflammation and tissue injury in the intestine, liver, skin and spleen. Gln therapy improved the score of clinical evidence of aGVHD and prolonged the median survival of aGVHD mice. Gin administration in aGVHD mice increased the fraction of Foxp3+/CD4+/CD25+ cells in the blood measured on day 7, and decreased the serum levels of tumor necrosis factor-a measured on days 7, 14 and 21 after aGVHD induction. These results demonstrated that Gln administration may be useful in protecting the host from aGVHD. (C) 2013 Elsevier Inc. All rights reserved.
