Figure 6.
Effect of LPS alone and in combination with Esc(1–21) (4 μM for wt-CFBE and 1 μM for F508del-CFBE) or with 1 μM of Esc(1–21)-1c (panel a) and effect of each Esc peptide alone (panel b) on IL-8 production from wt-CFBE (left panels) and F508del-CFBE cells (right panels), 20 h after treatment. Data are presented as the mean of four independent experiments ± SEM. The level of statistical significance between untreated Ctrl and Esc(1–21)/Esc(1–21)-1c treated cells or between other treatment groups are shown as: **P < 0.01; ***P < 0.001; ****P < 0.0001.
