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

    Tijana Ivanovic, Jason L Choi ... Stephen C Harrison
    Long-lived intermediate states formed by glycoprotein catalysts are an essential part of the process used by influenza virus particles to infect cells.

    Origins of the 2009 H1N1 influenza pandemic in swine in Mexico

    Ignacio Mena, Martha I Nelson ... Adolfo García-Sastre
    Genome sequence data from 58 Mexican swine influenza A viruses resolves the spatial origin of the virus that originated the influenza pandemic of 2009.

    Co-circulation of multiple influenza A reassortants in swine harboring genes from seasonal human and swine influenza viruses

    Pia Ryt-Hansen, Jesper Schak Krog ... Lars Erik Larsen
    The abundance and complex genetic diversity of swIAV were documented and the zoonotic potential evaluated.

    Recombinant single-cycle influenza virus with exchangeable pseudotypes allows repeated immunization to augment anti-tumour immunity with immune checkpoint inhibitors

    Matheswaran Kandasamy, Uzi Gileadi ... Vincenzo Cerundolo
    Immunization with NY-ESO-1 S-FLU virus elicits a robust NY-ESO-1-specific CTL response and suppresses the NY-ESO-1-expressing tumour development and spontaneous metastasis.

    IFN-λ prevents influenza virus spread from the upper airways to the lungs and limits virus transmission

    Jonas Klinkhammer, Daniel Schnepf ... Peter Staeheli
    Interferon-λ plays a decisive and previously underestimated role in limiting the spread of respiratory viruses from the nasal cavity to the lungs and it efficiently restricts virus transmission from infected individuals to naïve contacts.

    Increased public health threat of avian-origin H3N2 influenza virus caused by its evolution in dogs

    Mingyue Chen, Yanli Lyu ... Yipeng Sun
    During adaptation in dogs, H3N2 canine influenza viruses (CIVs) became to recognize human-like SAα2,6-Gal receptor, increased replication ability in human cells, acquired a 100% transmission rate via respiratory droplet in ferret model, and human population lacked immunity to H3N2 CIVs.

    Dynamically linking influenza virus infection kinetics, lung injury, inflammation, and disease severity

    Margaret A Myers, Amanda P Smith ... Amber M Smith
    Important nonlinear links between infection, inflammation, and disease severity were revealed using experimentally validated mathematical models.

    Stochastic processes constrain the within and between host evolution of influenza virus

    John T McCrone, Robert J Woods ... Adam S Lauring
    An analysis of influenza viruses from naturally infected people suggests a tight transmission bottleneck and little positive selection within hosts.

    Antigenic evolution of human influenza H3N2 neuraminidase is constrained by charge balancing

    Yiquan Wang, Ruipeng Lei ... Nicholas C Wu
    The local fitness landscape of an antigenic region in influenza neuraminidase was determined by combinatorial mutagenesis and next-generation sequencing.

    Human influenza virus infection elicits distinct patterns of monocyte and dendritic cell mobilization in blood and the nasopharynx

    Sindhu Vangeti, Sara Falck-Jones ... Anna Smed-Sörensen
    Patterns of monocyte and dendritic cell mobilization and function during human respiratory viral infections are tissue-specific and pathogen-specific, and future studies must perform comparative investigations in blood and the site of infection for a comprehensive assessment of immune responses.
