Th17 Cell Enhances CD8 T-Cell Cytotoxicity via IL-21 Production in Emphysema Mice
Figure 5
The frequencies of CD4+IL-17+(Th17) cells, IL-21+Th17 cells, and CD8+IL-21R+ T cells in lungs were measured by using flow cytometry. The frequencies (%) of CD4+IL-17+(Th17) cells (a), IL-21+Th17 cells (b), and CD8+IL-21R+ T cells (c) increased in lungs of CS-exposed mice compared with air-exposed mice. Results are expressed as % (mean ± SD). animals/group; *.
