Fig. 3: Human airway epithelial cells increase the expression of XO during RSV infection and induce inflammatory innate cytokines.

a Expression of XO in A549 infected with RSV compared with uninfected cells. b–d IL-33, TSLP, and CCL2 expression in A549 cells treated with XOI with or without RSV infection. e Expression of IFNβ in A549 cells treated with XOI with or without RSV infection. Data represents the mean ± SE from 4 replicates per group (experimental repeats 3). *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001, ****p ≤ 0.0001.
