    Science Forum: Viral factors in influenza pandemic risk assessment

    Marc Lipsitch et al.
    We identify key strengths and limitations in use of viral genotyping and phenotyping to estimate pandemic risk from influenza A viruses, focusing on 3 traits, hemagglutinin binding specificity, hemagglutinin pH of activation, and polymerase complex efficiency.

    Science Forum: Improving pandemic influenza risk assessment

    Colin A Russell et al.
    Predicting the pandemic potential of influenza viruses from genetic sequence data could transform pandemic risk assessment but progress towards this goal will require the integration of experimental work, computational tools, and virus surveillance.

    The global antigenic diversity of swine influenza A viruses

    Nicola S Lewis et al.
    Swine populations worldwide are sporadically infected by influenza viruses from humans and birds leading to geographically heterogeneous swine influenza virus populations that pose epizootic and pandemic threats.

    Integrating influenza antigenic dynamics with molecular evolution

    Trevor Bedford et al.
    Combined antigenic and genetic analysis shows that different strains of the human influenza virus display dramatically different rates of antigenic drift, and that these differences have a significant impact on the number of new infections in each flu season.

    Influenza-virus membrane fusion by cooperative fold-back of stochastically induced hemagglutinin intermediates

    Tijana Ivanovic et al.
    Long-lived intermediate states formed by glycoprotein catalysts are an essential part of the process used by influenza virus particles to infect cells.

    Conjunction of factors triggering waves of seasonal influenza

    Ishanu Chattopadhyay et al.
    Three complementary computational approaches reveal a set of putative causes of initiation of pan-USA waves of influenza.

    Enhanced ER proteostasis and temperature differentially impact the mutational tolerance of influenza hemagglutinin

    Angela M Phillips et al.
    Endoplasmic reticulum proteostasis factors enhance the mutational tolerance of influenza hemagglutinin, a model secretory pathway protein and therapeutic target, particularly improving the fitness of temperature-sensitive variants.

    pp32 and APRIL are host cell-derived regulators of influenza virus RNA synthesis from cRNA

    Kenji Sugiyama et al.
    The host-derived factors, pp32 and APRIL, interact with influenza viral RNA polymerase to support viral genomic RNA synthesis from complementary RNA.

    Mapping influenza transmission in the ferret model to transmission in humans

    Michael G Buhnerkempe et al.
    Influenza transmission among ferrets correlates strongly with transmission among humans, so the ferret model for influenza transmission is a valid tool for pandemic potential in humans.
