Infection with SeV results in induction of antiviral sensor expression.

<p>A) Analysis of <i>Mda5</i> and <i>Rig-I</i> mRNA expression in WT mice during the acute SeV infection period as determined by real-time PCR analysis. B) Micrographs taken of lung sections obtained from WT and MDA5^−/− mice infected with 200K pfu SeV and stained for MDA5 expression. N = 4, error bars refer to SEM, * P<0.05.
