Regulation of Pulmonary Graft-versus-Host Disease by IL-26+CD26+CD4 T Lymphocytes

Obliterative bronchiolitis is a potentially life-threatening noninfectious pulmonary complication after allogeneic hematopoietic stem cell transplantation and the only pathognomonic manifestation of pulmonary chronic graft-versus-host disease (cGVHD). In the current study, we identified a novel effect of IL-26 on transplant-related obliterative bronchiolitis. Sublethally irradiated NOD/Shi-scidIL2rγ(null) mice transplanted with human umbilical...
