Cellular profiles of recovered bronchoalveolar lavage (BAL) fluid. PM enhanced HDM‐induced allergic airway inflammation compared to HDM treatment‐alone. BALB/c mice were sensitized/challenged with PBS/PBS(control; white), PM/PBS (light gray), HDM/HDM (dark grey), or HDM + PM/HDM (black). Total cells, macrophages, eosinophils, neutrophils, and lymphocytes are shown in number of cells counted per milliliter (cells/mL). Data are presented as mean ± SEM (n = 4/group). Bars indicate a significant difference of P < 0.05 between groups.
