Apoptotic and Early Innate Immune Responses to PB1-F2 Protein of Influenza A Viruses Belonging to Different Subtypes in Human Lung Epithelial A549 Cells

Figure 7

Levels of secreted cytokine/chemokine levels in response to PB1-F2 expression in A549 cells measured by ELISArrays. Data are presented as absorbance values at 450 nm. Concentration of the cytokine/chemokines is in pg/ml. Asterisks () indicate (p < 0.05) and are calculated relative to the mock vector control which is also represented in the figure. This data is representative of three independent experiments. Error bars represent the ± SEM.
