Research Abstract |
A newly defined T cell subset called Th17 has been focused during these several years. Th17 is supposed to be induced by TGF β and IL-6 and to suppress regulatory T cells, which results in development of autoimmune diseases. We hypothesized that Th17 is involved in rejection of the graft after lung transplantation. Our experimental results using mouse model showed that Th17 is significantly induced in the local site of chronic rejection. Furthermore, bronchiolitis obliterans is suppressed by anti-IL6 antibody.
