Total and differential BALF cell counts. Smoke increased the influx of total cells (a), macrophages (b) and neutrophils (c) into the BALF of influenza infected mice, and altered the profile of lymphocyte influx (d). Clear boxes denote mice not infected with influenza and dark boxes denote mice infected with influenza, n = 8 in all groups. Data were analyzed by two-way ANOVA, and when significance was achieved, a Bonferroni post hoc test was used. The symbol * indicates a significant change (p < 0.05); ** p < 0.01, ***p < 0.001.
