Detection of the cytokine level in the BALF and the serum of mice at 72 h after challenge. The changes in the expression levels of cytokines in the BALF and serum of each group were detected by indirect ELISA, namely, the changes in IL-17 (a), Fas-ligand (b), IL-21 (c), G-CSF (d), MIP-1β/CCL4 (e), IL-1β (f), IL-6 (g), IL-10 (h), TNF-α (i), IL-18 (j), IFN-γ (k) and GM-CSF (l) levels. *, P < 0.05; **/***, P < 0.01
