Cytokine/chemokine levels in lung homogenates of aMPV/C- and sham-inoculated mice.

<p>Six mice from both aMPV/C- and sham-inoculated groups were sacrificed on days 1, 2, 3, 4, 5, 6, 7, 10, 14, and 21 post-inoculation, and 100 μl of lung homogenates was used to quantify IL-1β (A), IFN-γ (B), MCP-1 (C), MIP-1α (D), RANTES (E), and TNF-α (F) by enzyme-linked immunosorbent assay. Significant difference is expressed as <i>p</i><0.05 (*) for a comparison of aMPV/C-inoculated and sham-inoculated mice at the indicated time points after inoculation. Data are shown as the mean ± standard deviations (SD).
