Fig 5. TCP treatment results in more severe lung injuries in IAV-infected mice.

The PBS or TCP were admitted to Mock-infected or WSN-infected mice as above, and mice were sacrificed at Day 9 post-infection. Lung tissues from each group were collected and a representative result were shown in A. (B) The lungs were further sectioned, and stained with hematoxylin and eosin (H&E) for the histopathological analysis. Representative results were shown in B.
