Th17 Cell Enhances CD8 T-Cell Cytotoxicity via IL-21 Production in Emphysema Mice

Figure 4

The frequency of CD4⁺IL-17⁺(Th17), cells, IL-21⁺Th17 cells and CD8⁺IL-21R⁺ T cells in peripheral blood was measured by using flow cytometry. The frequency (%) of CD4⁺IL-17⁺(Th17) cells (a), IL-21⁺Th17 cells (b), and CD8⁺IL-21R⁺ T cells (c) increased in peripheral blood of CS-exposed mice compared with air-exposed mice. Results are expressed as % (mean ± SD). 𝑛=10 animals/group; *𝑃<0.05.
