FIG. 3.
Late therapeutic treatment. Shown are flow cytometry results following late (day 6 p.i.) therapeutic treatment of mice with anti-SP and anti-F antibodies. (A) Total pulmonary leukocyte trafficking. (B to F) BAL were stained with antibodies against CD8+ (B), CD4+ (C), B220+ (D), and CD11b+ (E) cells and PMN (RB6-8C5+) (F). The data are expressed as the number (103) of BAL/lung (± SEM) on days 3, 5, 7, and 9 p.i. A representative experiment from two independent experiments is shown. Asterisks indicate a significant difference (P < 0.05) between nIg-treated and antibody-treated mice.
