Effect of O3 on lung permeability, airway neutrophilia, and mucus production in adult (6-week old) TLR4−/− mice compared to wild-type (WT) mice. (a) Albumin levels measured in the BAL fluids (mean ± SEM, n = 4–7/group), (b) Number of neutrophils recovered in the BAL fluids (mean ± SEM, n = 4–7/group), (c) Epithelial Muc5ac expression (mean ± SEM, n = 3–6/group), (d) Muc5ac levels in the BAL fluids (mean ± SEM, n = 5–10/group). *: p < 0.05, compared with age-matched FA-exposed controls; #: Statistical difference between the groups (p < 0.05)
