    Structural basis for SARM1 inhibition and activation under energetic stress

    Michael Sporny, Julia Guez-Haddad ... Yarden Opatowsky
    Cryo-EM shows that the NADase activity of SARM1 is allosterically inhibited by physiological concentrations of NAD+ that stabilizes an auto-inhibited conformation of SARM1, explaining how NAD+ depletion may inflict neurodegeneration.

    Cold protection allows local cryotherapy in a clinical-relevant model of traumatic optic neuropathy

    Yikui Zhang, Mengyun Li ... Wencan Wu
    Local deep hypothermia combined with hibernation-mimicking cold protection is neuroprotective in a translatable large animal model of traumatic optic neuropathy.

    Impact of long- and short-range fibre depletion on the cognitive deficits of fronto-temporal dementia

    Melissa Savard, Tharick A Pascoal ... Pedro Rosa-Neto
    While semantic symptoms in fronto-temporal dementia patients were mainly dependent on short-range white-matter fibre disruption, long-range white-matter fibres damage was the major contributor to executive dysfunction, highlighting the importance of controlling for risk factors associated with deep white-matter disease.

    Muscle-resident mesenchymal progenitors sense and repair peripheral nerve injury via the GDNF-BDNF axis

    Kyusang Yoo, Young-Woo Jo ... Young-Yun Kong
    GDNF receptor-expressing mesenchymal progenitor subpopulation within skeletal muscle responds to peripheral nerve injury by sensing GDNF and secreting BDNF, thereby directly promoting nerve regeneration through facilitating remyelination by Schwann cells.

    Neurotoxin-mediated potent activation of the axon degeneration regulator SARM1

    Andrea Loreto, Carlo Angeletti ... Michael P Coleman
    The identification of the mechanism of action of vacor, an environmental neurotoxin which causes neurodegeneration by activating the pro-degenerative enzyme SARM1, raises important questions on SARM1 as a mediator of environmental neurotoxicity and has implications for drug discovery.

    Activity disruption causes degeneration of entorhinal neurons in a mouse model of Alzheimer’s circuit dysfunction

    Rong Zhao, Stacy D Grunke ... Joanna L Jankowsky
    Chemogenetic silencing reveals that entorhinal neurons require ongoing activity for survival, suggesting that their normal physiology may render them vulnerable to pathologies that impair transmission.

    Silicone oil-induced ocular hypertension and glaucomatous neurodegeneration in mouse

    Jie Zhang, Liang Li ... Yang Hu
    An effective and reversible mouse glaucoma model that replicates the secondary glaucoma in human patients caused by silicone oil after retina surgeries presents significant neurodegeneration, and is suitable for neuroprotectants selection.

    Live imaging reveals the cellular events downstream of SARM1 activation

    Kwang Woo Ko, Laura Devault ... Aaron DiAntonio
    Axon degeneration occurs via an ordered sequence of events downstream of SARM1 that proceeds from ATP loss, to defects in mitochondrial movement and depolarization, followed by calcium influx, phosphatidylserine externalization, loss of membrane permeability, and ending with catastrophic axonal self-destruction.

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

    Guiping Wang, David J Simon ... Xiaowei Zhuang
    Neurotrophin deprivation leads to rapid caspase-independent disassembly of the actin-spectrin-based membrane skeleton and spectrin-dependent retrograde signaling in axon degeneration.
