TRPM2 channel ablation does not alter allergic airway inflammation. A) Ranked inflammation scores for alveolar, peribronchiolar and perivascular regions of the lung, prepared by staining with hematoxylin and eosin, from OVA and saline-challenged WT and TRPM2-/- mice. B-F) BAL cells were collected, identified and enumerated microscopically using Diff-Quick stained preparations. Total cell numbers (B) and numbers of eosinophils (C), macrophages (D), lymphocytes (E), and neutrophils (F) in the BAL fluid, and mast cells (G) in toluidine blue-stained lung tissue of WT and TRPM2-/- mice challenged with saline or OVA. Except for mast cells, cell numbers were significantly increased by OVA challenge in both WT and TRPM2-/- mice, but no significant difference was seen between WT and TRPM2-/- mice. Data are shown as means ± SEM from 10 mice per group (* indicates p < 0.05).
