HBE culture characteristics upon <i>Bp</i> infection.

CBF was quantified from slow-motion capture of 240 frames-per-second. TEER was measured using an epithelial voltohmeter, with 300 Ohms·cm2 as the cut-off for acceptable epithelium integrity. Percent LDH was quantified from basal supernatants. Percent acetylated-α-tubulin was quantified from Fig 4B. Mean values are represented, with standard error of the mean values in parentheses. Data represent at least two independent experiments. Significance was calculated by using one-way ANOVA. *, p < 0.05 compared to uninfected HBE cells; #, p < 0.05 compared to HBE cells infected with WT.
