Protein levels of IL-1ra in wild-type and PPTA^−/− mice in lung (A) and plasma (B). IL-1ra levels in lung and plasma were measured 8 h after CLP or sham surgery in wild-type and PPTA^−/− mice by ELISA as described in Materials and Methods. Results were expressed as mean ± SEM (n = 6−12 mice per group). P values were determined by one-way ANOVA, followed by post hoc Tukey test.
