Inflammatory cells in bronchoalveolar lavage fluid (BALF). Mice were infected or mock-infected with RSV or cell supernatant on day 0 and then inoculated with LPS as described in the materials and methods part. BALF was collected and inflammatory cells were counted. a: Total inflammatory cells. b: Monocytes. c: Neutrophils. d: Lymphocytes. e: Eosinophils. Graphs are represented as the mean ± sem. Data are representative of two independent experiments performed on 8 animals per group. *, p < 0.05, **, p < 0.01, ***, p < 0.001, shown comparing the control group with the other groups; #, p < 0.05, ###, p < 0.001, shown comparing the RSV + LPS group with the LPS group; ^, p < 0.05, ^^, p < 0.01, ^^^, p < 0.001, shown comparing the RSV + LPS group with the RSV group
