PM10 induces cell recruitment in the airways. Murine model of C57BL6 mice exposed to PM10 (10 and 100 µg/dose). (A) Scheme of exposure to PM10. (B) Record of body weight (in grams), (C) total cell count in BALF (total cells/mL), (D) differential count (% cells), (E) representative photographs of histological sections and (F) lung histopathology score. The data are presented as the median ± IQR (n = 6). Statistical comparison was made using the Kruskal-Wallis test with a confidence level of 95%, and Dunn’s HDS post hoc (or multiple reference points) tests were applied. Significant differences * p < 0.05; ** p < 0.01
