    Rice Ragged Stunt Virus Propagation and Infection on Rice Plants
    Authors:  Chao Zhang, Chaonan Shi, Dong Chen and Jianguo Wu, date: 10/20/2018, view: 20, Q&A: 0
    Virus inoculation is a basic experimental procedure to evaluate the resistance of a rice variety or a transgenic material upon virus infection. We recently demonstrated that Rice Ragged Stunt Virus (RRSV), an oryzavirus that is ...
    Detection and Differentiation of Multiple Viral RNAs Using Branched DNA FISH Coupled to Confocal Microscopy and Flow Cytometry
    Authors:  Nicholas van Buuren and Karla Kirkegaard, date: 10/20/2018, view: 29, Q&A: 0
    Due to the exceptionally high mutation rates of RNA-dependent RNA polymerases, infectious RNA viruses generate extensive sequence diversity, leading to some of the lowest barriers to the development of antiviral drug resistance in the microbial ...
    HIVGKO: A Tool to Assess HIV-1 Latency Reversal Agents in Human Primary CD4+ T Cells
    Authors:  Emilie Battivelli and Eric Verdin, date: 10/20/2018, view: 22, Q&A: 0
    While able to suppress HIV replication in HIV infected individuals, combination antiretroviral therapy (ART) fails to eliminate viral latent reservoir, which consists in integrated transcriptional silenced HIV provirus. So far, identification of ...
    H1N1 Virus Production and Infection
    Authors:  Binbin Zhao, Jiaoyu Shan, Rui Xiong, Ke Xu and Bin Li, date: 10/20/2018, view: 20, Q&A: 0
    Influenza A virus is a member of orthomyxoviridae family causing wide-spread infections in human respiratory tract. Mouse infection model is widely used in antiviral research and pathogenesis study against influenza A virus. Here, we report a ...

    Authors:  Chao Zhang, Chaonan Shi, Dong Chen and Jianguo Wu, date: 10/20/2018, view: 20, Q&A: 0
    [Abstract] Virus inoculation is a basic experimental procedure to evaluate the resistance of a rice variety or a transgenic material upon virus infection. We recently demonstrated that Rice Ragged Stunt Virus (RRSV), an oryzavirus that is transmitted by brown planthopper (BPH), can suppress jasmonic acid-mediated antiviral defense through ...
    Detection and Differentiation of Multiple Viral RNAs Using Branched DNA FISH Coupled to Confocal Microscopy and Flow Cytometry
    Authors:  Nicholas van Buuren and Karla Kirkegaard, date: 10/20/2018, view: 29, Q&A: 0
    [Abstract] Due to the exceptionally high mutation rates of RNA-dependent RNA polymerases, infectious RNA viruses generate extensive sequence diversity, leading to some of the lowest barriers to the development of antiviral drug resistance in the microbial world. We have previously discovered that higher barriers to the development of drug resistance can be ...
    HIVGKO: A Tool to Assess HIV-1 Latency Reversal Agents in Human Primary CD4+ T Cells
    Authors:  Emilie Battivelli and Eric Verdin, date: 10/20/2018, view: 22, Q&A: 0
    [Abstract] While able to suppress HIV replication in HIV infected individuals, combination antiretroviral therapy (ART) fails to eliminate viral latent reservoir, which consists in integrated transcriptional silenced HIV provirus. So far, identification of latently-infected cells has relied on activating cells to induce expression of HIV proteins which can ...
    H1N1 Virus Production and Infection
    Authors:  Binbin Zhao, Jiaoyu Shan, Rui Xiong, Ke Xu and Bin Li, date: 10/20/2018, view: 20, Q&A: 0
    [Abstract] Influenza A virus is a member of orthomyxoviridae family causing wide-spread infections in human respiratory tract. Mouse infection model is widely used in antiviral research and pathogenesis study against influenza A virus. Here, we report a protocol in infected mice with different virus doses and strains to explore how an inhibitor of ...
    Expression and Ni-NTA-Agarose Purification of Recombinant Hepatitis C Virus E2 Ectodomain Produced in a Baculovirus Expression System
    [Abstract] In this protocol, we describe the production and purification of the ectodomain of the E2661 envelope protein (amino acids 384-661) of the Hepatitis C virus, which plays a fundamental role in the entry of the virus into the host cell. This protein has been expressed in both prokaryotic and eukaryotic systems but in small quantities or ...
    Sendai Virus Propagation Using Chicken Eggs
    Authors:  Narihito Tatsumoto, Moshe Arditi and Michifumi Yamashita, date: 09/20/2018, view: 230, Q&A: 0
    [Abstract] Sendai virus is a member of the family Paramyxoviridae, and an enveloped virus with a negative-stranded RNA genome. Sendai virus is not pathogenic to humans, but for mice and can cause pneumonia in mice. Easy and efficient techniques for propagating Sendai virus are required for studying virus replication, virus-induced innate- and ...
    Retroviral Capsid Core Stability Assay
    Authors:  Tyler Milston Renner, Kasandra Bélanger and Marc-André Langlois, date: 09/20/2018, view: 380, Q&A: 0
    [Abstract] Structural stability of the capsid core is a critical parameter for the productive infection of a cell by a retrovirus. Compromised stability can lead to premature core disassembly, exposure of replication intermediates to cytosolic nucleic acid sensors that can trigger innate antiviral responses, and failure to integrate the proviral genome into ...
    Selective Isolation of Retroviruses from Extracellular Vesicles by Intact Virion Immunoprecipitation
    Authors:  Tyler Milston Renner, Kasandra Bélanger and Marc-André Langlois, date: 09/05/2018, view: 261, Q&A: 0
    [Abstract] There exists a wide variety of techniques to isolate and purify viral particles from cell culture supernatants. However, these techniques vary greatly in ease of use, purity, yield and impact on viral structural integrity. Most importantly, it is becoming evident that secreted extracellular vesicles (EVs) co-purify with retroviruses using nearly ...
    Analysis of the Effect of Sphingomyelinase on Rubella Virus Infectivity in Two Cell Lines
    Authors:  Noriyuki Otsuki, Masafumi Sakata, Yoshio Mori, Kiyoko Okamoto and Makoto Takeda, date: 09/05/2018, view: 229, Q&A: 0
    [Abstract] Rubella is a mildly contagious disease characterized by low-grade fever and a morbilliform rash caused by the rubella virus (RuV). Viruses often use cellular phospholipids for infection. We studied the roles of cellular sphingomyelin in RuV infection. Treatment of cells with sphingomyelinase (SMase) inhibited RuV infection in rabbit kidney-derived ...
    Liposome Flotation Assay for Studying Interactions Between Rubella Virus Particles and Lipid Membranes
    Authors:  Kyoko Saito, Noriyuki Otsuki, Makoto Takeda and Kentaro Hanada, date: 08/20/2018, view: 410, Q&A: 0
    [Abstract] Rubella virus (RuV) is an enveloped, positive-sense single-stranded RNA virus that is pathogenic to humans. RuV binds to the target cell via the viral envelope protein E1, but the specific receptor molecules on the target cell are yet to be fully elucidated. Here, we describe a protocol for liposome flotation assay to study direct interactions ...
