Dose-dependent airway inflammation induced by NP5 in mice. Mice received a single lung administration of 25, 50 or 100 µg of NP5 or saline (CTL), and airway inflammation was assessed 24 h later by counting cells (a) and measuring cytokines (b) in bronchoalveolar lavage fluids. Data are means ± SEM of n = 6 mice. Statistical differences when compared to controls (CTL) were determined by one-way ANOVA followed by the Dunnett’s test. *p < 0.05; **p < 0.01; ***p < 0.001
