| Research Abstract |
Lung transplantation has been established as the curative treatment for chronic progressive severe respiratory failure. Rejection of the graft is, however,most common in lung transplantation and graft survival is the poorest among all the organ transplantations. Therefore, suppression of rejection is essential to improve the long-term outcome of lung transplantation. We showed that Th17 cells induced by IL-6 play an important role in bronchiolitis obliterans (BO) which is supposed to the result of chronic rejection after lung transplantation.
In the present study, we further clarified that IL-6 amplifier, EGF, and CCL2 BO are involved in initiation of BO in the animal model as well as the clinical specimens. These results are supposed to lead to innovation of the novel method to suppress chronic rejection after lung transplantation.
