FIG. 8.
Induction of IFN-β mRNA during HRV1a infection in cells with reduced IRF-3. mi-L1221 or mi-IRF-3 cells were infected with HRV1a or SeV, total cellular RNA was harvested at the times indicated, and IFN-β mRNA was detected by SYBR green qRT-PCR. Results were normalized to PBDG mRNA copy number and are displayed as the change in induction relative to uninfected cells using the ΔΔCT method (where CT is threshold cycle). p.i., postinfection.
