Lung histological analysis and scoring of control and asthma mice after A/PR8 influenza infection. The inflammation score in lung (A) and the representative histology pictures of lung tissues at magnification x200 (B) after A/PR8 influenza virus infection. Lung tissues were collected at 5 days post infection and stained with hematoxylin and eosin (H&E). Lung inflammation score were blindly quantified (20–22 pictures/group) between 0–3, using publishing criteria: 0 (normal), 1 (mild), 2 (moderate) and 3 (severe). All data were shown in mean ± SEM. For statistical analysis, one-way ANOVA and Tukey’s post-multiple comparison test were performed. *p < 0.05; **p < 0.01; ***p < 0.001 ****p < 0.0001 between the indicated groups
