Changes in inflammatory and anti-viral gene expression by SWCNTs and IAV. SAEC were singly exposed to 50 μg/ml SWCNTs, 5.0 MOI IAV or pre-treated with 50 μg/ml SWCNTs for 24 h followed by exposure to 5.0 MOI IAV for 24 h. qRT-PCR was performed on isolated RNA for the targets shown above. Data are presented as the mean fold expression ± standard error and represent a total of 3 separate experiments. Significant differences in expression levels were determined by ANOVA; *compared to control for each treatment; + significant differences between treatments (P < 0.05).
