Cytokine responses in lungs of infected mice.

<p>Groups of three BALB/c mice were inoculated intranasally with 10⁵ pfu of SD16 or SD16-MA virus. The lungs of mice were collected at 3 dpi. The concentrations of various cytokines in lung homogenates were measured by a protein array analysis with Bio-Plex Mouse Cytokine 8-Plex. Each value represents mean cytokine concentration of three mice from each infected group ± SD. *, <i>P</i><0.05 compared with the value of SD16 infected mice.
