From: Chronic allergic asthma induces T-cell exhaustion and impairs virus clearance in mice
OVA sensitization and challenge induced chronic asthma in mice. Sera and lung Samples were collected at 6 weeks post OVA sensitization. (A) OVA-specific IgE level in sera were measured by ELISA. Data of OVA-specific sera IgE were shown in mean ± SEM. For statistical analysis, two-way ANOVA and Sidak’s-multiple comparison test were performed. ****p < 0.0001 between the indicated groups (n = 4/group). (B) Lung tissues were stained with hematoxylin and eosin (H&E) and the representative histological analysis of each group at magnification x200 was shown
