Outline of Final Research Achievements

I have reported the inflammatory role of γδ T cells that expressed NK1.1 in PBMCs in interstitial lung disease (ILD) mice models. In humans, mouse NK1.1 is homologous with CD161.
The proportion of CD161+γδT cells was significantly higher in systemic sclerosis (SSc) than healthy controls (HCs) and correlated negatively with serum KL-6 levels in ILD-positive SSc patients. CD161+γδT cells in ILD-positive SSc patients showed lower production of IFN-γ than in HCs. These findings suggest that CD161+γδT cells may play a regulatory role in the pathogenesis of ILD in SSc patients via IFN-γ production.
In bleomycin-induced ILD model mice, pulmonaryγδT cells were expanded and produced large amounts of IFN-γand IL-17A. Th17 cell differentiation was suppressed in the presence of IFN-γ producingγδT cells. These results suggested that pulmonaryγδT cells seem to play a regulatory role in the development of ILD via the suppression of IL-17A production.
