    Strong confinement of active microalgae leads to inversion of vortex flow and enhanced mixing

    Debasmita Mondal, Ameya G Prabhune ... Prerna Sharma
    Coupling between cell motility and strong confinement alters the force generators that cause flow fields to change their handedness and lead to enhanced mixing.

    Analyzing the brainstem circuits for respiratory chemosensitivity in freely moving mice

    Amol Bhandare, Joseph van de Wiel ... Nicholas Dale
    Recordings from brainstem nuclei involved in chemosensory regulation of breathing in awake freely behaving mice show different complementary types of neuronal responses to hypercapnia in the retrotrapezoid nucleus and the rostral medullary raphe.

    Functional coupling between TRPV4 channel and TMEM16F modulates human trophoblast fusion

    Yang Zhang, Pengfei Liang ... Huanghe Yang
    A previously unknown calcium channel in human placental trophoblasts provides a calcium source for activating TMEM16F lipid scramblase that flip-flops phospholipids on cell surface, demonstrating a physiological mechanism that helps to understand how lipid dynamics regulates cell fusion.

    Phenotypic complementation of genetic immunodeficiency by chronic herpesvirus infection

    Donna A MacDuff, Tiffany A Reese ... Herbert W Virgin
    HOIL-1 deficiency in mice results in a severe immunodeficiency that is effectively complemented by chronic infection with a murine gamma-herpesvirus.

    Neurogenetic dissection of the Drosophila lateral horn reveals major outputs, diverse behavioural functions, and interactions with the mushroom body

    Michael-John Dolan, Shahar Frechter ... Gregory SXE Jefferis
    The generation and systematic characterisation of driver lines labelling a large number of neurons in the Drosophila innate olfactory processing centre bridges electron microscopy neuronal reconstructions, circuits and behaviour.

    Transcriptional profiling of mouse peripheral nerves to the single-cell level to build a sciatic nerve ATlas (SNAT)

    Daniel Gerber, Jorge A Pereira ... Ueli Suter
    Establishing transcriptional profiles of nerve-inhabitant cells as resource to foster the fundamental understanding of peripheral nerves.

    Adaptor linked K63 di-ubiquitin activates Nedd4/Rsp5 E3 ligase

    Lu Zhu, Qing Zhang ... Scott D Emr
    Arrestin-related trafficking adaptors (ARTs) undergo a K63 linked di-ubiquitin modification to promote Rsp5 E3 ligase recruitment and enhance cargo protein ubiquitination.

    Cell-sized confinement controls generation and stability of a protein wave for spatiotemporal regulation in cells

    Shunshi Kohyama, Natsuhiko Yoshinaga ... Nobuhide Doi
    A cell-sized fully confined space significantly controls the emergence and stability of a protein wave, resulting in intracellular spatiotemporal regulation driven by a reaction-diffusion mechanism.

    The co-receptor Tetraspanin12 directly captures Norrin to promote ligand-specific β-catenin signaling

    Elise S Bruguera, Jacob P Mahoney, William I Weis
    Biophysical binding and structural prediction studies reveal that Tetraspanin12 directly binds the ligand Norrin, in a manner that is negatively cooperative with Norrin-Fzd4 binding and competitive with Norrin-LRP5/6 binding.

    Activation of polycystin-1 signaling by binding of stalk-derived peptide agonists

    Shristi Pawnikar, Brenda S Magenheimer ... Yinglong Miao
    Structural dynamic insights revealed the mechanisms of PC1 activation by stalk-derived peptide agonists which can form a foundation for development of PC1 as a therapeutic target for ADPKD treatment.
