    Cell-cycle quiescence maintains Caenorhabditis elegans germline stem cells independent of GLP-1/Notch

    Hannah S Seidel, Judith Kimble
    C. elegans germline stem cells become quiescent under starved conditions, and this quiescence maintains the stem cell state even in the absence of GLP-1/Notch signaling, which is otherwise essential for stem cell maintenance.

    HIV Tat controls RNA Polymerase II and the epigenetic landscape to transcriptionally reprogram target immune cells

    Jonathan E Reeder et al.
    Tat uses unexpected regulatory mechanisms to reprogram target immune cells to promote viral replication and rewire pathways beneficial for HIV.

    T cell immunodominance is dictated by the positively selecting self-peptide

    Wan-Lin Lo et al.
    The T cell repertoire can display immunodominance to an epitope as a result of optimal positive selection in the thymus by one self-peptide/MHC ligand.

    A longitudinal study of Caenorhabditis elegans larvae reveals a novel locomotion switch, regulated by Gαs signaling

    Stanislav Nagy et al.
    C. elegans exhibits two distinct behavioural macro-states, active and quiet wakefulness, and protein kinase A regulates switching between these two states.

    Tumor evolutionary directed graphs and the history of chronic lymphocytic leukemia

    Jiguang Wang et al.
    A general framework captures the evolutionary routes leading to the formation and progression of tumors.

    Synaptotagmin 1 directs repetitive release by coupling vesicle exocytosis to the Rab3 cycle

    Yunsheng Cheng et al.
    Experiments in C. elegans reveal how synaptotagmin and Rab3, the 'yin and yang' of synapses, control whether transmitter vesicles remain docked at the presynaptic membrane or release their contents into the synapse.

    HDAC3 restrains CD8-lineage genes to maintain a bi-potential state in CD4+CD8+ thymocytes for CD4-lineage commitment

    Rachael Laura Philips et al.
    CD4 lineage commitment requires HDAC3 to prevent premature upregulation of CD8 lineage genes during T cell development.

    Anatomical basis and physiological role of cerebrospinal fluid transport through the murine cribriform plate

    Jordan N Norwood et al.
    Chemical ablation of olfactory sensory neurons blocks cerebrospinal fluid outflow into the nasal epithelium, leading to alterations of cerebrospinal fluid dynamics.

    PLZF targets developmental enhancers for activation during osteogenic differentiation of human mesenchymal stem cells

    Shuchi Agrawal Singh et al.
    A key transcription-factor for osteogenic differentiation, PLZF, acts as a transcriptional activator by binding to active developmental enhancers and facilitates mediator recruitment, but is not involved in enhancer looping.

    Adequate immune response ensured by binary IL-2 and graded CD25 expression in a murine transfer model

    Franziska Fuhrmann et al.
    A murine adoptive transfer model shows that binary IL-2 and graded CD25 expression tailor the T helper cell response to the antigen amount in vivo.
