    Epitope resurfacing on dengue virus-like particle vaccine preparation to induce broad neutralizing antibody

    Wen-Fan Shen et al.
    Despite size heterogeneity, an epitope-resurfaced mature-form dengue VLP has the potential to induce quaternary structure-recognizing broad cross-reactive neutralizing antibodies.

    Long read sequencing reveals poxvirus evolution through rapid homogenization of gene arrays

    Thomas A Sasani et al.
    An adaptive process of genetic homogenization in poxviruses facilitates the propagation of single nucleotide variation within gene copies and might favor the persistence of large gene copy arrays.

    DNA-PK is a DNA sensor for IRF-3-dependent innate immunity

    Brian J Ferguson et al.
    Experiments in mice have shown than an enzyme that repairs broken DNA inside the nucleus also has a central role in the innate immune system because it is able to detect foreign DNA outside the nucleus.

    A single vertebrate DNA virus protein disarms invertebrate immunity to RNA virus infection

    Don B Gammon et al.
    Novel virus-host systems yield insights into how Lepidopterans (moths and butterflies) combat RNA virus infection and reveal that poxvirus A51R proteins can suppress the host's immune system and stabilize microtubules in host cells.

    Elevation of CpG frequencies in influenza A genome attenuates pathogenicity but enhances host response to infection

    Eleanor Gaunt et al.
    Mutants of influenza A virus with increased CpG dinucleotide frequencies show restricted replication and reduced or absent pathogenicity, and powerful host innate and adaptive responses to infection that confer immunity to re-infection.

    Genetic epidemiology of dengue viruses in phase III trials of the CYD tetravalent dengue vaccine and implications for efficacy

    Maia A Rabaa et al.
    In large vaccine trials conducted in dengue-endemic Asia and Latin America, the CYD-TDV tetravalent dengue vaccine shows limited variation in intra-serotype efficacy in the target population for vaccination (>9 years).

    RNA virus attenuation by codon pair deoptimisation is an artefact of increases in CpG/UpA dinucleotide frequencies

    Fiona Tulloch et al.
    Attenuating candidate live virus vaccines by incorporating unfavoured codon pairs to reduce translation efficiency is actually mediated though changes in frequencies of CpG and UpA dinucleotides, which make viruses more visible to the innate immune system.

    Variant proteins stimulate more IgM+ GC B-cells revealing a mechanism of cross-reactive recognition by antibody memory

    Bronwen R Burton et al.
    Investigation of antibody responses to variant Dengue virus proteins demonstrate new mechanisms that could increase the potential for vaccines to protect against mutable pathogens such as Flu, Dengue and HIV.

    Herpes simplex type 2 virus deleted in glycoprotein D protects against vaginal, skin and neural disease

    Christopher Petro et al.
    An attenuated Herpes simplex type 2 virus deleted in glycoprotein D can be used as an effective vaccine to provide robust transferable humoral immunity and complete protection in murine intravaginal and skin infection models.
