    Nur77 prevents excessive osteoclastogenesis by inducing ubiquitin ligase Cbl-b to mediate NFATc1 self-limitation

    Xiaoxiao Li et al.
    Orphan nuclear receptor Nur77 protects bone by enabling a timely termination of osteoclast differentiation.

    T cell-specific inhibition of multiple apoptotic pathways blocks negative selection and causes autoimmunity

    Megan L Burger et al.
    Using mice expressing a Bcl-2 mutant protein to suppress multiple central tolerance pathways, it is shown that central tolerance is crucial for preventing autoimmunity.

    IgM and IgD B cell receptors differentially respond to endogenous antigens and control B cell fate

    Mark Noviski et al.
    Self-reactive B cells downregulate the IgM but not the IgD B cell receptor, and this serves as a critical tolerance mechanism because IgD is less sensitive to bona fide endogenous antigens than IgM.

    High mTOR activity is a hallmark of reactive natural killer cells and amplifies early signaling through activating receptors

    Antoine Marçais et al.
    Chronic engagement of Natural killer cell inhibitory receptors by MHC-I molecules maintains a high activity of the mTOR pathway allowing subsequent amplification of signaling through activating receptors upon acute stimulation.

    Non-canonical antagonism of PI3K by the kinase Itpkb delays thymocyte β-selection and renders it Notch-dependent

    Luise Westernberg et al.
    Antagonistic signaling by the kinases PI3K and Itpkb limits the kinetics and enforces the Notch-dependence of beta-selection – the most important cell-fate determining process in alpha beta T cell development.

    Affinity and dose of TCR engagement yield proportional enhancer and gene activity in CD4+ T cells

    Karmel A Allison et al.
    Pre-existing enhancers interpret T cell signaling strength in an analogue manner to direct quantitative changes in gene expression within the context of an overall digital response.

    Tissue-specific shaping of the TCR repertoire and antigen specificity of iNKT cells

    Rebeca Jimeno et al.
    The tissue environment shapes the lipid recognition capacity of natural killer T cells.

    Arp2/3 complex-driven spatial patterning of the BCR enhances immune synapse formation, BCR signaling and B cell activation

    Madison Bolger-Munro et al.
    Arp2/3 complex-mediated actin polymerization shapes how B lymphocytes probe the surface of antigen-presenting cells, promotes coalescence of B cell receptor (BCR) microclusters, amplifies BCR signaling, and enhances B cell activation.

    The E3 ubiquitin ligase TRIM23 regulates adipocyte differentiation via stabilization of the adipogenic activator PPARγ

    Masashi Watanabe et al.
    TRIM23 plays a critical role in the switching from early to late adipogenic enhanceosomes by stabilizing the PPARγ protein.

    B cell receptor and Toll-like receptor signaling coordinate to control distinct B-1 responses to both self and the microbiota

    Lieselotte SM Kreuk et al.
    Microbial-sensing TLRs drive responses to the microbiota, while nucleic-acid sensing TLRs control responses to endogenous ligands, revealing novel regulation of B-1a responses through integrated BCR/TLR mediated activation.
