Figure 9. vIRFs are not needed for efficient suppression of type I IFN production during primary lytic infection of HDLMECs.
(A) Schematic of the experiment. Primary HDLMECs were infected by WT or ΔvIRF KSHV for 48 hours followed by SeV infection for 6 hours. (B) IFNβ gene expression in the absence of SeV infection was analyzed by RT-qPCR at 54 hpi. (C) IFNβ in the supernatant was measured by bead-based immunoassay. (D) IFNβ gene expression in the presence of SeV infection was measured by RT-qPCR at 54 hpi. Dashed line indicates the limit of assay detection. Error bars represent standard deviation (n=3). ns: non-significant.
