Inflammation scores of lung tissue histopathology after RSV challenge.

Inflammation scores were blindly determined by examining the histology slides under the microscope as shown in the Fig 5. FI-RSV MN patch delivery with MPL attenuates histopathology after RSV challenge. (A) Inflammation scores around the airways. (B) Inflammation scores around blood vessels. (C) Inflammation scores around interstitial spaces. (D) Stained lung sections were scored for bronchiolar mucus production as the percentages of PAS positives. Results (n = 5) are presented as mean ± SEM. Statistical significances were performed by one-way ANOVA and Tukey’s multiple-comparison tests in GraphPad Prism; *** p<0.001, **p<0.01, *p<0.05.
