Effect of O3 on lung permeability, airway neutrophilia, and mucus production in neonatal (1-week old) TLR4−/− mice compared to wild-type (WT) mice. (a) Levels of albumin measured in the BAL fluid (mean ± SEM, n = 3–5/group), (b) Numbers of neutrophils recovered in the BAL fluids (mean ± SEM, n = 3–5/group), (c) Epithelial Muc5ac expression (mean ± SEM, n = 3–5/group), (d) Levels of Muc5ac in the BAL fluid (mean ± SEM, n = 3–5/group). *: p < 0.05, compared with age-matched FA-exposed controls; #: Statistical difference between the groups (p < 0.05)
