Figure 2

Cytokine and chemokine mRNA levels at various time points post-infection. NCI-H292 cells were infected with influenza A virus subtypes: H1N1/2002, H5N1/2004, and H9N2/1997 viruses at m.o.i. = 1. Real-time PCR were used to quantitify the mRNA levels and fold-changes were calculated by ΔΔCT method as compared with non-infection cell control and using endogeneous actin mRNA level for normalization. Each point on the graph represents the mean fold change in gene expression relative to NI - non-infected cells level ± SE (p* < 0.05).
