    Dynamic repression by BCL6 controls the genome-wide liver response to fasting and steatosis

    Meredith A Sommars et al.
    B cell lymphoma 6 (BCL6) represses fasting gene expression by opposing peroxisome proliferator-activated receptor alpha (PPARa) activity at enhancers, and its ablation protects against steatosis by enhancing fatty acid catabolism.

    Cytotoxic T-cells mediate exercise-induced reductions in tumor growth

    Helene Rundqvist et al.
    Exercise can induce metabolic changes that strikingly impact cytotoxic T cell function and in turn affect cancer progression.

    An integrin/MFG-E8 shuttle loads HIV-1 viral-like particles onto follicular dendritic cells in mouse lymph node

    Chung Park, John H Kehrl
    Intravital imaging with HIV-1 viral-like particle in mouse model reveals a mechanism for HIV-1 uptake by subcapsular sinus macrophages that facilitates HIV-1 spreading tofollicular dendritic and B cells.

    TGFβ-dependent expression of PD-1 and PD-L1 controls CD8+ T cell anergy in transplant tolerance

    Marije Baas et al.
    The interplay between the cytokine TGFβ and the PD-1/PD-L1 pathway promotes CD8+ T cell anergy and tolerance towards transplanted tissues.

    A population of innate myelolymphoblastoid effector cell expanded by inactivation of mTOR complex 1 in mice

    Fei Tang et al.
    A novel population of hematopoietic cells unmasked by mTORC1 inactivation reveals a new mechanism of innate immune tolerance and a new consequence of defective hematopoiesis.

    Tumor-induced MDSC act via remote control to inhibit L-selectin-dependent adaptive immunity in lymph nodes

    Amy W Ku et al.
    Tumor-induced myeloid-derived suppressor cells exert systemic suppression of adaptive immunity by limiting L-selectin-directed trafficking of T cells at vascular checkpoints in lymph nodes.

    Different promoter affinities account for specificity in MYC-dependent gene regulation

    Francesca Lorenzin et al.
    Differences in promoter affinity and MYC levels explain distinct expression profiles induced by physiological and oncogenic MYC.

    Cytotoxic T cells swarm by homotypic chemokine signalling

    Jorge Luis Galeano Niño et al.
    Killer T cells swarm around tumour targets by accelerating the recruitment of distant T cells, which upon arrival and target engagement augment the chemotactic signal in a positive feedback loop.

    Identification of a super-functional Tfh-like subpopulation in murine lupus by pattern perception

    Stefanie Gryzik et al.
    A novel binning approach provides evidence for super-functional T cells with high activation potential and which exhibit Tfh-like functionalities and can help B cells.

    MYC regulates ribosome biogenesis and mitochondrial gene expression programs through its interaction with host cell factor–1

    Tessa M Popay et al.
    Interaction of oncoprotein transcription factor MYC with chromatin-associated protein host cell factor–1 controls expression of genes important for ribosome biogenesis and mitochondrial vigor, loss of which promotes tumor regression.
