IL-37 treatment modulates immune responses to H1N1 infection. BALF, serum and lung homogenates were harvested 6 d.p.i. following IL-37 treatment. The levels of G-CSF, GM-CSF, IFN-γ, MIG, IL-1α, IL-1β, IL-4, IL-5, IL-6, IL-10, IL-12p70, IL-13, IL-17A, RANTES, MCP-1, MIP-1α, MIP-1β, and TNF, in lung homogenates (A), BAL fluid (B) as well as serum samples (C) were measured quantitatively using a Cytometric Beads Array. There were no significant differences in the concentrations of other cytokines and chemokines tested (data not shown). (D) The relative mRNA expression of cytokines in lung tissues were detected by real-time RT-PCR. Data are representative of three independent experiments with three mice for each group. *Significant difference (p < 0.05), compared with oseltamivir-inoculated mice. # Significant difference (p < 0.05), compared with H1N1-infected mice.
