From: Chronic allergic asthma induces T-cell exhaustion and impairs virus clearance in mice
Th2/Th1 ratio and T cell exhaustion marker expression of lung cells of asthma mice. (A) Intracellular cytokine level of IL-4 and IFN-γ in T cell of the lung of control and asthma mice were measured. (B) T cell exhaustion marker expression in CD4 and CD8 T cells in lung. Data were measured by flow cytometry. All result were shown in mean ± SEM. For statistical analysis, unpaired T tests were performed. *p < 0.05, **p < 0.01, ***p < 0.001 between the indicated groups (n = 4/group)
