Abstract

Background Although interleukin-17 (IL-17) has been reported to participate in the pathogenesis of infectious, autoimmune and allergic disorders, the precise role in allograft rejection remains uncertain. This study illustrates that IL-17 contributes to the pathogenesis of chronic allograft rejection. Result Utilizing a murine heterotopic heart transplant model system, IL-17-deficient recipient mice had decreased allograft inflammatory cell recruitment, decreased IL-6, MCP-1, and KC production, and reduced graft coronary artery disease (GCAD). Intragraft gamma delta (γδ) T cells appear to be the predominant source of IL-17 production. Conclusion Therefore, IL-17 neutralization may provide a potential target for novel therapeutic treatment for cardiac allograft rejection.
