    Structural plasticity of actin-spectrin membrane skeleton and functional role of actin and spectrin in axon degeneration

    Guiping Wang et al.
    Neurotrophin deprivation leads to rapid caspase-independent disassembly of the actin-spectrin-based membrane skeleton and spectrin-dependent retrograde signaling in axon degeneration.

    Venous endothelin modulates responsiveness of cardiac sympathetic axons to arterial semaphorin

    Denise M Poltavski et al.
    Second-order guidance, a novel mechanism by which an initial guidance cue controls expression of a second guidance receptor, is required for precise refinement of axon trajectories during PNS development.

    Node of Ranvier length as a potential regulator of myelinated axon conduction speed

    I Lorena Arancibia-Cárcamo et al.
    Node of Ranvier length is similar at successive nodes along single myelinated CNS axons, but differs between axons, and could potentially be tuned to adjust the conduction velocity of each axon.

    Developmental mechanism of the periodic membrane skeleton in axons

    Guisheng Zhong et al.
    Super-resolution imaging reveals how the skeleton that supports the outer membrane of axons is assembled during development, and provides an explanation for why this structure preferentially forms in axons but rarely in dendrites.

    MAP7 regulates axon morphogenesis by recruiting kinesin-1 to microtubules and modulating organelle transport

    Stephen R Tymanskyj et al.
    An under-studied microtubule-associated protein is found to regulate axon growth and branching by modulating microtubule-based organelle transport through its dual interactions with microtubules and the conventional kinesin motor.

    Axon injury triggers EFA-6 mediated destabilization of axonal microtubules via TACC and doublecortin like kinase

    Lizhen Chen et al.
    Severing axons in C. elegans reveals a mechanism by which the axons sense acute damage and respond by sequential remodeling of their microtubule cytoskeleton.

    Gradient-reading and mechano-effector machinery for netrin-1-induced axon guidance

    Kentarou Baba et al.
    Shootin1a, through its spatially regulated phosphorylation within growth cones, mediates the gradient reading and mechanoresponse for netrin-1-induced axon guidance.

    Retrograde Ret signaling controls sensory pioneer axon outgrowth

    Adam Tuttle et al.
    Long-range Ret receptor signaling promotes axon outgrowth and regulates growth cone dynamics in pioneer neurons by inducing transcriptional changes in Myosin-X expression.

    Akt1-Inhibitor of DNA binding2 is essential for growth cone formation and axon growth and promotes central nervous system axon regeneration

    Hyo Rim Ko et al.
    Akt mediated S14 phosphorylation of Id2 augments its protein stability and growth cone localization, promoting growth cone formation and axon growth in the developing neuron and contributing to axon regeneration in the damaged hippocampus slice.

    Regulation of retinal axon growth by secreted Vax1 homeodomain protein

    Namsuk Kim et al.
    Secreted Vax1 homeodomain protein supports the development of optic chiasm by directly acting at the retinal ganglion cell axon.
