Figure 6From: Heterogeneous pathological outcomes after experimental pH1N1 influenza infection in ferrets correlate with viral replication and host immune responses in the lungGene expressions of proapoptotic genes and IHC of apoptotic cells in lungs of pH1N1-infected ferrets at 4 and 7 dpi. (A) Comparison of BAX and CASP8 gene expression levels in lungs with both severe and mild lesions as measured by RT-qPCR. The data expresses the means with SEMs. (B) and (C) IHC staining for caspase3 in the lungs of the ferrets with mild (B) and severe (C) lesions; haematoxylin counterstain (40× objective field).Back to article page
