ジャーナル Am J Transplant
Abstract IL-26 is a Th17 cytokine, with its gene being absent in rodents. To characterize the in vivo immunological effects of IL-26 in chronic systemic inflammation, we used human IL26 transgenic (hIL-26Tg) mice and human umbilical cord blood mononuclear cells (hCBMC) in mouse allogeneic-graft-versus-host disease (GVHD) and chronic xenogeneic-GVHD model, respectively. Transfer of bone marrow and spleen T cells from hIL-26Tg mice into B10.BR mice resulted in GVHD progression, with clinical signs of tissue damage in multiple organs. IL-26 markedly increased neutrophil levels both in the GVHD-target tissues and peripheral blood. Expression levels of Th17 cytokines in hIL-26Tg mice-derived donor CD4 T cells were significantly increased, whereas IL-26 did not affect cytotoxic function of donor CD8 T cells. In addition, granulocyte-colony stimulating factor, IL-1β, and IL-6 levels were particularly enhanced in hIL-26Tg mice. We also developed a humanized neutralizing anti-IL-26 monoclonal antibody (mAb) for therapeutic use, and its administration after onset of chronic xenogeneic-GVHD mitigated weight loss and prolonged survival, with preservation of graft-versus-leukemia effect. Taken together, our data elucidate the in vivo immunological effects of IL-26 in chronic GVHD models and suggest that a humanized anti-IL-26 mAb may be a potential therapeutic agent for the treatment of chronic GVHD.
