The single cell suspensions of mouse lung tissue were prepared and detected with flow cytometry. a: Macrophages. b: Neutrophils. c: NK cells. d: T cells. e: B cells. 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 < 0.01, shown comparing the RSV + LPS group with the RSV group
