    A novel Drosophila injury model reveals severed axons are cleared through a Draper/MMP-1 signaling cascade

    Maria D Purice et al.
    An unbiased transcriptional profiling screen reveals the secreted matrix metalloproteinase MMP-1 is a transcriptional target of the ensheathing glial receptor Draper following acute axon injury in adult Drosophila.

    Altered potassium channel distribution and composition in myelinated axons suppresses hyperexcitability following injury

    Margarita Calvo et al.
    Type 1 potassium channels alter their composition and localisation to suppress hyper-excitability and neuropathic pain of injured sensory neurons.

    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.

    Axon-dependent expression of YAP/TAZ mediates Schwann cell remyelination but not proliferation after nerve injury

    Matthew Grove et al.
    YAP and TAZ, potent concoproteins and therapeutic targets in cancer therapy, are essential for Schwann cells to support peripheral nerve regeneration.

    GSK3β regulates AKT-induced central nervous system axon regeneration via an eIF2Bε-dependent, mTORC1-independent pathway

    Xinzheng Guo et al.
    The AKT-GSK3β-eIF2Bε signaling module plays a key role in promoting axon regeneration in the adult mammalian central nervous system.

    Microtubule-dependent ribosome localization in C. elegans neurons

    Kentaro Noma et al.
    The utility of split GFP for tissue-specific visualization of ribosomes in live Caenorhabditis elegans demonstrates the link between ribosomes and microtubules.

    Cell-specific exon methylation and CTCF binding in neurons regulate calcium ion channel splicing and function

    Eduardo Javier López Soto, Diane Lipscombe
    Cell-specific alternative splicing of the synaptic calcium channel gene Cacna1b is controlled by exon hypomethylation and CTCF binding and is disrupted following nerve injury.

    Expanded genetic screening in Caenorhabditis elegans identifies new regulators and an inhibitory role for NAD+ in axon regeneration

    Kyung Won Kim et al.
    A function-based genetic screen using the Caenorhabditis elegans axotomy model identifies new regulators and an inhibitory role for NAD+ in axon regeneration, expanding the understanding of axon injury responses and regeneration.

    Chromatin accessibility dynamics and single cell RNA-Seq reveal new regulators of regeneration in neural progenitors

    Anneke Dixie Kakebeen et al.
    Regenerating neural progenitors of the Xenopus tropicalis tail prioritize differentiation to motor neuron types earlier than proliferation, a decision partly regulated by the transcription factors Pbx3 and Meis1.
