    Galectin-9 regulates the threshold of B cell activation and autoimmunity

    Logan K Smith, Kareem Fawaz, Bebhinn Treanor
    Galectin-9-deficient mice develop spontaneous autoimmunity, driven by a decreased threshold of B cell activation and enhanced auto-antigen delivery to the spleen by increased B1a-derived autoantibodies.

    Polycomb enables primitive endoderm lineage priming in embryonic stem cells

    Robert S Illingworth, Jurriaan J Hölzenspies ... Joshua M Brickman
    Polycomb enables lineage priming in mouse embryonic stem cells by establishing a barrier to commitment.

    Selective dephosphorylation by PP2A-B55 directs the meiosis I-meiosis II transition in oocytes

    S Zachary Swartz, Hieu T Nguyen ... Arminja N Kettenbach
    Time-course phosphoproteomics reveals that selective dephosphorylation is critical for directing the MI/MII transition and that, through its inherent phospho-threonine preference, PP2A-B55 imposes specific phosphoregulated behaviors that distinguish the two meiotic divisions.

    Landscape of histone modifications in a sponge reveals the origin of animal cis-regulatory complexity

    Federico Gaiti, Katia Jindrich ... Miloš Tanurdžić
    The complex chromatin-based genomic regulatory system controlling developmental gene expression in complex bilaterians predates the evolution of morphological complexity and may have been a prerequisite for the evolution of the first simple multicellular animals.

    The Chd1 chromatin remodeler shifts hexasomes unidirectionally

    Robert F Levendosky, Anton Sabantsev ... Gregory D Bowman
    Oriented hexasomes can be generated using the Widom 601 positioning sequence, which enables straightforward production of nucleosomes with asymmetrically modified H2A/H2B dimers.

    RNA fusion in human retinal development

    Wen Wang, Xiao Zhang ... Zi-Bing Jin
    Chimeric RNAs are widely distributed spatiotemporally during human retinal development and have important regulatory functions, such as silencing of CTNNBIP1-CLSTN1 biasing the progenitor cells toward the RPE cell fate at the expense of neural retinal cell fates.

    Hierarchical sequence-affinity landscapes shape the evolution of breadth in an anti-influenza receptor binding site antibody

    Angela M Phillips, Daniel P Maurer ... Michael M Desai
    An anti-influenza receptor binding site antibody acquires breadth through hierarchical sets of epistatic mutations distributed across the light and heavy chains, demonstrating how mutations can interact to shape the evolution of antibody breadth in various antigen exposure regimens.

    Identification of HIV-reservoir cells with reduced susceptibility to antibody-dependent immune response

    Antonio Astorga-Gamaza, Judith Grau-Expósito ... Maria J Buzon
    The expression of CD32 in HIV-reservoir cells prevents the binding of specific anti-HIV antibodies conferring resistance to NK cell-mediated death, and gives the cell the potential to proliferate in the presence of immune complexes.

    IFI16, a nuclear innate immune DNA sensor, mediates epigenetic silencing of herpesvirus genomes by its association with H3K9 methyltransferases SUV39H1 and GLP

    Arunava Roy, Anandita Ghosh ... Bala Chandran
    The innate immune DNA sensor IFI16 is in association with H3K9 methyltransferases SUV39H1 and GLP under physiological conditions in the nucleus which facilitates the epigenetic silencing of foreign viral DNA.
