    TDP-43 maximizes nerve conduction velocity by repressing a cryptic exon for paranodal junction assembly in Schwann cells

    Kae-Jiun Chang et al.
    Glial TDP-43 regulates splicing and expression of neurofascin and is required for proper assembly and maintenance of paranodal axoglial junctions.

    The cooperative binding of TDP-43 to GU-rich RNA repeats antagonizes TDP-43 aggregation

    Juan Carlos Rengifo-Gonzalez et al.
    The RNA-mediated higher order assembly of TDP-43, a protein associated with neurodegenerative diseases, preserves its solubility by reducing the risk of multivalent interactions between low complexity domains.

    Traumatic injury compromises nucleocytoplasmic transport and leads to TDP-43 pathology

    Eric N Anderson et al.
    Traumatic injury leads to functional defects in nucleocytoplasmic transport and TDP-43 pathology in multiple model systems.

    Cytosolic calcium regulates cytoplasmic accumulation of TDP-43 through Calpain-A and Importin α3

    Jeong Hyang Park et al.
    Genetic and optogenetic analyses in Drosophila neurons reveal calcium as one of the key regulators of nucleocytoplasmic localization of TDP-43 via Calpain-A and Importin α3.

    Therapeutic genetic variation revealed in diverse Hsp104 homologs

    Zachary M March et al.
    Exploring natural Hsp104 variation reveals unexpected tuning of a passive activity that inhibits aggregation of specific substrates to selectively counter TDP-43 or alpha-synuclein proteotoxicity connected to neurodegenerative disease.

    Chronic optogenetic induction of stress granules is cytotoxic and reveals the evolution of ALS-FTD pathology

    Peipei Zhang et al.
    OptoGranules reveal the function of G3BP1 as a stress granule scaffold and demonstrate that protracted stress granule assembly is sufficient to drive neurodegeneration and the evolution of ALS-FTD pathology.

    Glycolysis upregulation is neuroprotective as a compensatory mechanism in ALS

    Ernesto Manzo et al.
    Degenerating motor neurons compensate for energetic deficits by upregulating glycolysis in flies and humans, with increased glucose availability improving locomotor function and lifespan in flies.

    Unexpected similarities between C9ORF72 and sporadic forms of ALS/FTD suggest a common disease mechanism

    Erin G Conlon et al.
    Idiopathic patients along a complex motor neuron disease-dementia spectrum exhibit mRNA splicing changes that are due to multi-protein insolubility.

    Suppression of C9orf72 RNA repeat-induced neurotoxicity by the ALS-associated RNA-binding protein Zfp106

    Barbara Celona et al.
    Zfp106 functions as an RNA binding protein, binds directly to GGGGCC RNA repeats, is required in motor neurons to prevent ALS-like neurodegeneration in mice, and can suppress neurotoxicity in an established fly model of ALS.

    Mechanisms of opening and closing of the bacterial replicative helicase

    Jillian Chase et al.
    Analysis of the Escherichia coli DnaB helicase•bacteriophage λ helicase loader (λP) complex provides insights into helicase opening, delivery to the origin and ssDNA entry, and closing in preparation for translocation.
