Viruses and viral components can be potent inducers of alpha/beta interferons (IFN-alpha/beta). In culture, IFN-alpha/beta prime for their own expression, in response to viruses, through interferon regulatory factor 7 (IRF-7) induction. The studies presented here evaluated the requirements for functional IFN receptors and the IFN signaling molecule STAT1 in IFN-alpha/beta induction during infec...
Kaposi's sarcoma-associated herpesvirus (KSHV)/human herpesvirus-8-encoded viral interferon regulatory factor (vIRF) transforms NIH3T3 cells, represses interferon signal transduction and regulates the expression of other KSHV genes. Here, we have shown that vIRF is a transcriptional activator and auto-activates its own expression. Ectopic expression of vIRF activated the vIRF promoter in KSHV-n...
Noroviruses (NVs) cause the majority of cases of epidemic nonbacterial gastroenteritis worldwide and contribute to endemic enteric disease. However, the molecular mechanisms responsible for immune control of their replication are not completely understood. Here we report that the transcription factor interferon regulatory factor 1 (IRF-1) is required for control of murine NV (MNV) replication a...
West Nile virus (WNV), a mosquito-borne, single-stranded RNA flavivirus, causes significant human morbidity and mortality in the older population; thus, we investigated the effects of aging on infection with WNV in dendritic cells (DCs). We infected DCs with WNV in vitro and quantified cytokines and chemokines (type I IFN and CXCL10), pathogen recognition receptors RIG-I, and Toll-like receptor...
