Mean (±SEM) lung keratinocyte–derived chemokine (KC), TNF-α, and IL-10 levels 6 and 24 hours after intratracheal administration of P. aeruginosa. In (A) and (B), mice were infected with P. aeruginosa at a dose of 1.1 × 106 CFU. BALFs were collected at 6 hours after infection and measured for KC and TNF-α expression by ELISA with determinations made in triplicate. In (C) and (D), BALFs were collected at 24 hours after infection and measured for KC and TNF-α expression. (E) Endogenous IL-10 (mouse IL-10) and exogenous IL-10 (human IL-10) levels were measured by ELISA in a similar manner from 6- and 24-hour BALF samples. *P < 0.05 compared with control group; **P < 0.01 compared with control group; ***P < 0.001 compared with control group. P.a., Pseudomonas aeruginosa.
