Lung cytokines response.

<p>Mice (n = 12/group) were infected i.n. with 10⁴ PFU of V_K627 (▪), rV_K627E (□), Ts_E627 (▾), and rTs_E627K (∇). Lungs from three mice per virus group per time point were harvested and homogenized in 1 ml of PBS. Cytokine levels were measured individually and in duplicate. Baseline cytokine levels from PBS inoculated mice (n = 5) are shown as a dashed line in each cytokine graph. The data shown represents mean ± SD for three independent experiments. <b>*</b><i>p</i><0.05 between V_K627 and rV_K627E; <b>ˆ</b><i>p</i><0.05 between Ts_E627 and rTs_E627K.
