Lentiviral Knockdown of Transcription Factor STAT1 in Peromyscus leucopus to Assess Its Role in the Restriction of Tick-borne Flaviviruses
[Abstract]  Cellular infection with tick-borne flaviviruses (TBFVs) results in activation of the interferon (IFN) signaling pathway and subsequent upregulation of numerous genes termed IFN stimulated genes (ISGs) (Schoggins et al., 2011). Many ISGs function to prevent virus pathogenesis by acting in a broad or specific manner through protein-protein interactions (Duggal and Emerman, 2012). The potency of the IFN signaling response determines the outcome of TBFV infection (Best, 2016; Carletti et al., 2017). Interestingly, data from our lab show that TBFV replication is significantly restricted in cells of the reservoir species Peromyscus leucopus thereby suggesting a potent antiviral response (Izuogu et al., 2017). We assessed the relative contribution of IFN ...

Infection of Caenorhabditis elegans with Vesicular Stomatitis Virus via Microinjection
[Abstract]  Over the past 15 years, the free-living nematode, Caenorhabditis elegans has become an important model system for exploring eukaryotic innate immunity to bacterial and fungal pathogens. More recently, infection models using either natural or non-natural nematode viruses have also been established in C. elegans. These models offer new opportunities to use the nematode to understand eukaryotic antiviral defense mechanisms. Here we report protocols for the infection of C. elegans with a non-natural viral pathogen, vesicular stomatitis virus (VSV) through microinjection. We also describe how recombinant VSV strains encoding fluorescent or luciferase reporter genes can be used in conjunction with simple fluorescence-, survival-, and luminescence-based assays to ...

FICZ Exposure and Viral Infection in Mice
[Abstract]  The aryl hydrocarbon receptor (AHR) is known as a sensor for dioxins that mediates their toxicity, and also has important biophysiological roles such as circadian rhythms, cell differentiation and immune responses. 6-formylindolo(3,2-b)carbazole (FICZ), which is derived through the metabolism of L-tryptophan by ultraviolet B irradiation, is one of putative physiological ligands for AHR (Smirnova et al., 2016). It has recently been shown that endogenously-activated AHR signaling modulates innate immune response during viral infection (Yamada et al., 2016). This section describes how to treat mice with FICZ and to infect them with virus.
