Interleukin 35 (IL-35) blockade upregulated the production of proinflammatory cytokines and downregulated anti-inflammatory cytokines during ARDS models. Cytokine and chemokine concentrations in BALF and blood specimens from five mice treated with or without anti–Ebi3 or anti–P35 blocking antibodies were determined by mice cytokine/chemokine magnetic bead panel kit assays 24 h after onset of ARDS. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001, by the one-way ANOVA followed by LSD multiple comparisons test, compared with mice treated with isotypical IgG control. ARDS featured increased CXCL-1, TNF-α, IL-6, and IL-17A and reduced IFN-γ, IL-10, IL-2, and IL-13 after neutralizing antibody treatment (anti-IL-35 Ebi3 or anti-IL-35 P35) in BALF and serum.
