    Identification of a critical sulfation in chondroitin that inhibits axonal regeneration

    Craig S Pearson, Caitlin P Mencio ... Herbert M Geller
    4-sulfation at the non-reducing end of chondroitin sulfate glycosaminoglycan chains is essential for inhibition of axonal growth.

    Selective rab11 transport and the intrinsic regenerative ability of CNS axons

    Hiroaki Koseki, Matteo Donegá ... James W Fawcett
    Mature axons lose the ability to regenerate because key growth molecules are excluded through changes in vesicle transport, and restoring transport can restore regeneration.

    Loss of adult skeletal muscle stem cells drives age-related neuromuscular junction degeneration

    Wenxuan Liu, Alanna Klose ... Joe V Chakkalakal
    Building on previous work (Liu et al., 2015), it is shown that depletion or rescue of adult skeletal muscle stem cells is sufficient to induce or attenuate age-associated neuromuscular junction deterioration respectively.

    scRNA-sequencing reveals subtype-specific transcriptomic perturbations in DRG neurons of PirtEGFPf mice in neuropathic pain condition

    Chi Zhang, Ming-Wen Hu ... Yun Guan
    Single-cell RNA-sequencing unraveled cell subtype-specific transcriptomic changes in both injured and uninjured primary sensory neurons after nerve injury and demonstrated transcriptomic sexual dimorphism.

    Proof of concept for multiple nerve transfers to a single target muscle

    Matthias Luft, Johanna Klepetko ... Konstantin Davide Bergmeister
    A murine model for a novel surgical concept demonstrates potential advances of neuroprosthetic interfacing.

    Inducible depletion of adult skeletal muscle stem cells impairs the regeneration of neuromuscular junctions

    Wenxuan Liu, Lan Wei-LaPierre ... Joe V Chakkalakal
    Skeletal muscle stem cells play important roles in the regeneration of neuromuscular junctions, and so present new targets for therapies to treat neuromuscular decline observed in the context of aging and various neuromuscular diseases.

    The structure and organization of lanceolate mechanosensory complexes at mouse hair follicles

    Lishi Li, David D Ginty
    Close examination of lanceolate mechanosensory complexes has revealed clues about the ways that sensory nerves detect the movement of hairs and shown than terminal Schwann cells are needed to maintain and regenerate these intricate structures.

    3D visualization of macromolecule synthesis

    Timothy J Duerr, Ester Comellas ... James R Monaghan
    Whole mount 3D visualization of macromolecule synthesis with light sheet fluorescence microscopy enables quantitative, multiscale analysis at the organ, cellular, and molecular levels of organization.

    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.

    Multiple neuronal networks coordinate Hydra mechanosensory behavior

    Krishna N Badhiwala, Abby S Primack ... Jacob T Robinson
    Despite lacking traditional ganglia or centralization, the Hydra nervous system computes sensorimotor responses via localized neuron ensembles.
