Effects of CD8⁺γδ T cells on eosinophilia and macrophages in the bronchoalveolar lavage. (a) The percentage of major basic protein (MBP) positive eosinophils in bronchoalveolar lavage fluid. Major basic protein positive eosinophils in CD8⁺γδ T-cell group were significantly lower compared to the PBS group. The eosinophilia was partially restored in the IFN-γ depleted CD8⁺γδ T cell group. (b) The number of major basic protein positive macrophages were more numerous in the CD8⁺γδ T cells group than in the PBS group. This increase was absent in the IFN-γ depleted CD8⁺γδ T cells group. (c) Ratio of major basic protein positive macrophages to eosinophils. The median, 25th, 75th, percentiles are shown. The ratio was higher in CD8⁺γδ T-cell group than in PBS group. In the IFN-γ depleted CD8⁺γδ T-cell group, the ratio was lower than in the CD8⁺γδ T-cell group.
