Figure 4. Neutrophils mediated inflammation attenuated in IL-17⁻/⁻ mice.

(A) Neutrophils in BALF between the WT and KO mice. (B) MPO activity in BALF between the WT and KO mice. (C) Infiltrated neutrophils and the degree of inflammation were obviously attenuated in the lung tissue of the mice completely lacking IL-17. (A,B) *p < 0.05, compared with the WT mice. The error bars indicate SEM. All mice were harvested on D2, and there were 3~6 mice per group.
