Treatment with anti-CCL11 during RSV challenge of rVV-G-primed mice alters the balance of CD4⁺ and CD8⁺ T cells recruited to the lungs. Combined data from four independent experiments show total BAL cell infiltrates (a), numbers of CD4⁺ (open bars) and CD8⁺ (filled bars) T cells recovered from BAL fluid (b), and ratios of CD4⁺ to CD8⁺ cells (c). Means ± SEM for each group are shown. P values are represented as follows: *, P < 0.05; **, P < 0.01; ***, P < 0.001; ns, not significant.
