    Plasmacytoid dendritic cells control dengue and Chikungunya virus infections via IRF7-regulated interferon responses

    Brian Webster, Scott W Werneke ... Marlène Dreux
    In vivo study of arbovirus infections reveals the dominant role of pDC IRF7-signaling in directing both type I and II IFN responses, and leading to viral control.

    Secreted dengue virus NS1 from infection is predominantly dimeric and in complex with high-density lipoprotein

    Bing Liang Alvin Chew, AN Qi Ngoh ... Dahai Luo
    Molecular architecture of the secreted NS1 dimer from dengue virus infection in complex with a high density lipoprotein particle.

    Targeting the Annexin A1-FPR2/ALX pathway for host-directed therapy in dengue disease

    Vivian Vasconcelos Costa, Michelle A Sugimoto ... Mauro Martins Teixeira
    An inadequate engagement of the inflammation resolution circuit centred on Annexin A1 contributes to the excessive inflammation observed in severe DENV infection, suggesting FPR2/ALX agonists as a therapeutic target for dengue disease.

    How small-molecule inhibitors of dengue-virus infection interfere with viral membrane fusion

    Luke H Chao, Jaebong Jang ... Stephen C Harrison
    Single-particle studies of dengue-virus membrane fusion and the effect of small-molecule inhibitors of infection clarify the viral fusion mechanism.

    Broadly neutralizing human antibodies against dengue virus identified by single B cell transcriptomics

    Natasha D Durham, Aditi Agrawal ... Leslie Goo
    Identification of viral and host determinants of broadly neutralizing antibodies targeting a new epitope on dengue virus that can be used to guide vaccine design.

    Dengue vascular leakage is augmented by mast cell degranulation mediated by immunoglobulin Fcγ receptors

    Ayesa Syenina, Cyril J Jagaraj ... Ashley L St John
    Building on previous work (St John et al., 2013), we explain why secondary infection by dengue virus is associated with more severe vascular disease than primary infection.

    Contributions of mast cells and vasoactive products, leukotrienes and chymase, to dengue virus-induced vascular leakage

    Ashley L St John, Abhay PS Rathore ... Soman N Abraham
    Proteins produced by mast cells modulate the permeability of blood vessels, and may determine whether patients infected with dengue virus develop life-threatening complications.

    An Aedes aegypti-associated fungus increases susceptibility to dengue virus by modulating gut trypsin activity

    Yesseinia I Angleró-Rodríguez, Octavio AC Talyuli ... George Dimopoulos
    Talaromyces (Tsp_PR) fungus render Aedes aegypti mosquitoes more susceptible to dengue virus infection through secreted molecules that impair midgut digestive enzyme transcription and activity.

    Opportunities for improved surveillance and control of dengue from age-specific case data

    Isabel Rodriguez-Barraquer, Henrik Salje, Derek A Cummings
    Age-specific incidence data, combined with mechanistic models of immunity, provides a unique opportunity to characterize disease transmission of dengue and other immunizing diseases at high temporal and spatial resolution.

    Using paired serology and surveillance data to quantify dengue transmission and control during a large outbreak in Fiji

    Adam J Kucharski, Mike Kama ... Martin L Hibberd
    A combination of surveillance data, paired sera and mathematical modelling reveals which factors may influence dengue transmission and control in island settings.
