Effect of anti-IL-17A on cellular composition of bronchoalveolar lavage fluid, CXCL2 and cytokine expression, and Penh to allergen inhalation in EC-sensitized mice. (A) Cells in bronchoalveolar lavage fluid. (B) Expression of mRNA for CXCL2, IL-4, IL-13, and IFN-γ. Values for lungs of saline-sensitized mice have been set to 1. (C) H&E staining of lung sections examined at magnification ×200 magnification. (D) Peak Penh after OVA-inhalation challenge. Columns and error bars represent means ± SEM (n = 5 per group). *, P < 0.05; **, P < 0.01; ***, P < 0.0001. SAL, saline.
