FIG. 6.
IL-8 production by flagellins from P. aeruginosa laboratory and clinical strains. (A) BEAS-2B cells were treated for 6 h with 100 ng/ml of the indicated flagellins, and IL-8 levels in culture supernatants were measured by ELISA. (B) IL-8 levels grouped according to clinical status or flagellin type. Each bar represents the mean ± SD (n = 3).
