Effect of inhalation exposure to TiO2 NP on cell number in the BALF. The number of total cells (A, B), neutrophils (C, D), lymphocytes (E, F), and alveolar macrophages (AM) (G, H) were counted using an automated hematology analyzer, and are shown by sex (males: A, C, E and G; females: B, D, F and H) (n = 5). Statistical significance was analyzed using Dunn’s or Dunnett’s multiple comparison test: *p < 0.05, **p < 0.01, and ***p < 0.001
