Amelioration of airway inflammation by T. spiralis ES protein-induced macrophage transfer before asthma induction. PenH was evaluated at baseline and after administration with increasing doses of aerosolized methacholine (0, 12.5, 25, and 50 mg/mL) at day 24 (A). All animals were sacrificed on day 25. After sacrificing the mice, the numbers of differential immune cells in the BALF were counted after Diff-Quik staining (B). The lungs were isolated from mice, fixed with 4% paraformaldehyde, stained with H&E, and then examined for histopathological changes under a microscope. Cytokine production was measured in lymphocytes isolated from BALF (DF) and LLN (G) by ELISA. White bar: 100 μm. Statistical analysis was performed with one-way ANOVA (*p < 0.05, ***p < 0.001; n = 3–5 mice/group; these results are representative of independent experiments).
