| Abstract | Acute graft-versus-host disease (aGVHD), the fatal side effects of bone marrow transplantation, was shown to be accompanied by elevation of serum levels of interleukin 18 (IL-18). In this study, the mechanism underlying the accumulation of IL-18 in aGVHD in mice was investigated. Lethally irradiated recipients having transplantation with H-2 disparate donor splenocytes demonstrated aGVHD and contained markedly elevated serum levels of IL-18. In contrast, recipients having transplantation with gld/gld spleen cells, which lack functional Fas ligand (FasL), contained only normal ranges of IL-18, indicating FasL-mediated IL-18 release in aGVHD. The wild-type hosts engrafted with caspase-1-deficient cells revealed marked increases of IL-18 similar to those engrafted with wild-type cells, whereas caspase-1-deficient recipients engrafted with wild-type cells showed only a slight elevation of serum IL-18, indicating that IL-18 elevation is derived from host cells in a caspase-1-dependent manner. These results suggest FasL-mediated caspase-1-dependent IL-18 secretion in aGVHD in mice. |
