    The major β-catenin/E-cadherin junctional binding site is a primary molecular mechano-transductor of differentiation in vivo

    Jens-Christian Röper et al.
    The primary molecular mechanosensor involved in a physiological process of mechanically induced cell fate differentiation is revealed here for the first time in vivo, highly sensitive and potentially shared by all metazoan epithelia.

    T cell receptor repertoires of mice and humans are clustered in similarity networks around conserved public CDR3 sequences

    Asaf Madi et al.
    A new perception of the organization of T-cell receptor repertoires in mice and humans, based on high-throughput sequencing and CDR3 sequence similarity, indicates hubs of cross-species public sequences forming evolutionary conserved 'foci of attention' of T cell immunity.

    Genetic specification of left–right asymmetry in the diaphragm muscles and their motor innervation

    Camille Charoy et al.
    Analysis of embryonic mouse diaphragm reveals muscle and nerve left–right asymmetries set by a Nodal-dependent genetic cascade, which imprints different molecular signatures to left and right motoneurons that shape their innervation pattern.

    9Å structure of the COPI coat reveals that the Arf1 GTPase occupies two contrasting molecular environments

    Svetlana O Dodonova et al.
    A molecular model of the assembled COPI coat, determined by cryo-electron tomography of an in vitro reconstituted budding reaction, reveals details of interactions mediating coat assembly and shows the binding site of ArfGAP2.

    A mutant with bilateral whisker to barrel inputs unveils somatosensory mapping rules in the cerebral cortex

    Nicolas Renier et al.
    The somatosensory cortex doesn't integrate mixed bilateral inputs, as partially uncrossing projections from the whiskers duplicates their representation by segregating lateralized inputs from each side of the head.

    Spatial organization shapes the turnover of a bacterial transcriptome

    Jeffrey R Moffitt et al.
    Transcriptome-scale RNA imaging and lifetime measurements reveal that the E. coli transcriptome is spatially organized and that this organization modulates the post-transcriptional fate of bacterial mRNAs.

    Insulin signaling controls neurotransmission via the 4eBP-dependent modification of the exocytotic machinery

    Rebekah Elizabeth Mahoney et al.
    By regulating protein translation within the neuron, insulin signaling can control neuronal activity by altering the release of neurotransmitter molecules.

    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.

    Atoh1-dependent rhombic lip neurons are required for temporal delay between independent respiratory oscillators in embryonic mice

    Srinivasan Tupal et al.
    The rhythmic patterns of activity that underlie breathing are generated and coordinated by distinct populations of neurons within the brainstem.

    Large-scale filament formation inhibits the activity of CTP synthetase

    Rachael M Barry et al.
    The accumulation of its product, cytidine triphosphate, encourages the enzyme CTP synthetase (CtpS) to form large-scale polymers and inhibits the enzyme's activity.
