    Proteolytically released Lasso/teneurin-2 induces axonal attraction by interacting with latrophilin-1 on axonal growth cones

    Nickolai V Vysokov, John-Paul Silva ... Yuri A Ushkaryov
    Lasso and latrophilin-1 interact across the synapse, while shed Lasso binds latrophilin-1 on distant growth cones and attracts them, providing a universal mechanism for short- and long-range axonal guidance.

    Angiopoietin-4-dependent venous maturation and fluid drainage in the peripheral retina

    Harri Elamaa, Minna Kihlström ... Lauri Eklund
    Identification of importance of Angiopoietin-4 (Angpt4) as a first growth factor that initiates venous specification in the peripheral retina, and Angpt4-dependent mechanism for fluid clearance in the mouse retina.

    Shear-induced damped oscillations in an epithelium depend on actomyosin contraction and E-cadherin cell adhesion

    Ehsan Sadeghipour, Miguel A Garcia ... Beth L Pruitt
    Cell movement toward and away from the midline of an epithelium over tens of hours are caused by spontaneous or externally-applied shear forces to eliminate force imbalances within the tissue.

    Bid maintains mitochondrial cristae structure and function and protects against cardiac disease in an integrative genomics study

    Christi T Salisbury-Ruf, Clinton C Bertram ... Sandra S Zinkel
    An integrative approach, combining genetic mouse and large-scale human genetics studies, was used to reveal a novel role for the Bcl-2 protein Bid in maintenance of mitochondrial function that alters susceptibility to myocardial infarction.

    Rescue of cognitive function following fractionated brain irradiation in a novel preclinical glioma model

    Xi Feng, Sharon Liu ... Nalin Gupta
    Whole-brain radiotherapy, but not glioma growth in distal region from the hippocampus, results in impaired recognition memory, which can be prevented by CSF-1R inhibitor-mediated microglia depletion.

    Aberrant information transfer interferes with functional axon regeneration

    Chen Ding, Marc Hammarlund
    Defects in synapse regeneration limit functional circuit recovery after nerve injury by misdirecting information via ectopic dendritic synapses, and also by functional and molecular deficits in reformed axonal synapses.

    Active presynaptic ribosomes in the mammalian brain, and altered transmitter release after protein synthesis inhibition

    Matthew S Scarnati, Rahul Kataria ... Kenneth G Paradiso
    Local presynaptic protein synthesis occurring at established nerve terminals in the mammalian brain provides a mechanism for rapidly controlling or restoring presynaptic proteins that affect neurotransmitter release and presynaptic efficiency.

    INAVA-ARNO complexes bridge mucosal barrier function with inflammatory signaling

    Phi Luong, Matija Hedl ... Wayne I Lencer
    Inflammatory bowel disease risk-gene, INAVA and the ARF-GEF ARNO, regulates non-canonical cortical actin assembly and IL-1b signaling to maintain epithelial homeostasis.

    Morphogenetic degeneracies in the actomyosin cortex

    Sundar Ram Naganathan, Sebastian Fürthauer ... Stephan W Grill
    Distinct molecular functions contribute to the same material property at larger scales leading to degenerate functionality.

    RalB directly triggers invasion downstream Ras by mobilizing the Wave complex

    Giulia Zago, Irina Veith ... Maria Carla Parrini
    By moving from correlations to causality in cancer signal transduction using optogenetics, the sufficiency of RalB activation to trigger invasion and the underlying molecular mechanisms were established.
