    Origin and role of the cerebrospinal fluid bidirectional flow in the central canal

    Olivier Thouvenin, Ludovic Keiser ... Claire Wyart
    The combination of data and modelling shows the mechanisms underlying bidirectional flow of cerebrospinal fluid and its impact on long range transport in the CSF between brain and spinal cord.

    Self-organized canals enable long-range directed material transport in bacterial communities

    Ye Li, Shiqi Liu ... Yilin Wu
    Mechanochemical coupling between interfacial force and biosurfactant kinetics can coordinate large-scale material transport in primitive life forms, suggesting a new principle to engineer self-organized microbial communities.

    Multivesicular bodies mediate long-range retrograde NGF-TrkA signaling

    Mengchen Ye, Kathryn M Lehigh, David D Ginty
    Multivesicular bodies deliver long-range retrograde nerve growth factor (NGF) signals and serve as essential signaling and sorting platforms in the cell soma, and multivesicular body (MVB) cargoes dictate their vesicular fate.

    BLOS1 mediates kinesin switch during endosomal recycling of LDL receptor

    Chang Zhang, Chanjuan Hao ... Wei Li
    BLOS1 is a new regulator of LDLR endosomal recycling through coordinating kinesins during long-range transport, and depletion of BLOS1 in mouse liver leads to aberrant lipid metabolism.

    Ankyrin-B is a PI3P effector that promotes polarized α5β1-integrin recycling via recruiting RabGAP1L to early endosomes

    Fangfei Qu, Damaris N Lorenzo ... Vann Bennett
    Ankyrin-B – through interactions with PI3P lipids, dynactin and RabGAP1L – functions as a critical node in the protein circuitry underlying polarized recycling of α5β1-integrin to enable haptotaxis along fibronectin gradients.

    Retrograde Ret signaling controls sensory pioneer axon outgrowth

    Adam Tuttle, Catherine M Drerup ... Alex V Nechiporuk
    Long-range Ret receptor signaling promotes axon outgrowth and regulates growth cone dynamics in pioneer neurons by inducing transcriptional changes in Myosin-X expression.

    Structure of Geobacter OmcZ filaments suggests extracellular cytochrome polymers evolved independently multiple times

    Fengbin Wang, Chi Ho Chan ... Daniel R Bond
    A cryo-EM structure of the bacterial OmcZ cytochrome filament provides evidence for the possibility that cytochrome polymers had multiple origins in bacteria.

    Wnt3 distribution in the zebrafish brain is determined by expression, diffusion and multiple molecular interactions

    Sapthaswaran Veerapathiran, Cathleen Teh ... Thorsten Wohland
    Wnt3 accomplishes long-range distribution by extracellular diffusion controlled by expression, tissue morphology, interactions with heparan sulfate proteoglycans, and co-receptor-mediated receptor binding to regulate brain development in zebrafish embryos.

    Computational analysis of long-range allosteric communications in CFTR

    Ayca Ersoy, Bengi Altintel ... Oded Lewinson
    A combination of computational approaches identifies a novel allosteric hotspot in cystic fibrosis transmembrane conductance regulator.

    Mechanism of Na+-dependent citrate transport from the structure of an asymmetrical CitS dimer

    David Wöhlert, Maria J Grötzinger ... Özkan Yildiz
    The high-resolution x-ray structure of an asymmetrical SeCitS dimer, present in the inward- and outward-facing state, provides a complete mechanism of substrate and ion translocation in a sodium-dependent symporter.
