    An evolutionarily conserved mechanism for cAMP elicited axonal regeneration involves direct activation of the dual leucine zipper kinase DLK

    Yan Hao et al.
    Axonal damage sensing kinase DLK is a direct target and mediator of the cAMP effector kinase PKA in a unified mechanism for stimulating axonal regeneration.

    The axonal actin-spectrin lattice acts as a tension buffering shock absorber

    Sushil Dubey et al.
    A linear array of spectrin tetramers imparts mechanical stability to axons by allowing spectrin domains to unfold reversibly when an axon is stretched, thereby acting as tension buffers.

    Genetic defects in β-spectrin and tau sensitize C. elegans axons to movement-induced damage via torque-tension coupling

    Michael Krieg et al.
    A conceptual framework and physical model shows how actin-spectrin networks and microtubule bundles can protect axons from mechanical stress.

    Distinct mechanisms underlie oral vs aboral regeneration in the cnidarian Hydractinia echinata

    Brian Bradshaw et al.
    Stem cell migration underlies head regeneration in the cnidarian (jellies and their kin) Hydractinia, but the regeneration of other body parts is based on the gradual transformation of one tissue type into another.

    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.

    Ephrin-A/EphA specific co-adaptation as a novel mechanism in topographic axon guidance

    Felix Fiederling et al.
    A distinctive novel mechanism of ephrin-A/EphA signaling modulation in retinal growth cones ensures concurrent quantitative accuracy and adaptability of topographic hardwiring.

    Ionic mechanisms underlying history-dependence of conduction delay in an unmyelinated axon

    Yang Zhang et al.
    Conduction velocity of action potentials in unmyelinated axons depends ultimately on the gating variables of the fast voltage-gated sodium current and can be predicted from the action potential peak and trough voltages.

    Rapid changes in tissue mechanics regulate cell behaviour in the developing embryonic brain

    Amelia J Thompson et al.
    During embryonic development, tissue stiffness, which provides an important signal to motile cells, changes locally within tens of minutes in a well-controlled manner.

    CELF RNA binding proteins promote axon regeneration in C. elegans and mammals through alternative splicing of Syntaxins

    Lizhen Chen et al.
    Genetics and genomics approaches reveal a conserved post-transcriptional regulatory mechanism that promotes adult axon regeneration from worm to mammals.

    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.
