    Kinesin-4 KIF21B limits microtubule growth to allow rapid centrosome polarization in T cells

    Peter Jan Hooikaas et al.
    Kinesin-4 KIF21B promotes rapid reorientation of the microtubule network during formation of immunological synapse in T cells by acting as a pausing and catastrophe-inducing factor that keeps microtubules short.

    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.

    eNOS-induced vascular barrier disruption in retinopathy by c-Src activation and tyrosine phosphorylation of VE-cadherin

    Takeshi Ninchoji et al.
    Vascular leakage from pathological vessels in retinopathy aggravates the disease, but endothelial junction stability and barrier integrity can be restored by blocking formation of nitric oxide.

    Age-dependent electroencephalogram (EEG) patterns during sevoflurane general anesthesia in infants

    Laura Cornelissen et al.
    Alpha EEG oscillations emerge at 4 months of age during sevoflurane general anesthesia, and unlike in adults, have a widespread spatial distribution that likely reflects differences in brain development.

    Concerted action of kinesins KIF5B and KIF13B promotes efficient secretory vesicle transport to microtubule plus ends

    Andrea Serra-Marques et al.
    The function and distribution of kinesin motors on exocytotic vesicles is dissected and visualized through a combination of gene knockout experiments, high-resolution microscopy and advanced data analysis.

    Intracellular uptake of macromolecules by brain lymphatic endothelial cells during zebrafish embryonic development

    Max van Lessen et al.
    The discovery of a unique brain lymphatic cell type in the zebrafish model will facilitate the study of embryonic development and physiology, an essential mission to understand how clearance of macromolecules impact neurological diseases.
    1. Neuroscience

    Long ascending propriospinal neurons provide flexible, context-specific control of interlimb coordination

    Amanda M Pocratsky et al.
    Conditional silencing of long ascending propriospinal neurons disrupts interlimb coordination of the fore and hindlimb pairs, but in a highly context-specific manner.

    PUMILIO hyperactivity drives premature aging of Norad-deficient mice

    Florian Kopp et al.
    Long noncoding RNA Norad performs an essential function in mammalian physiology by inhibiting the activity of PUMILIO RNA binding proteins, thereby suppressing a multi-system degenerative phenotype resembling premature aging.
    1. Cell Biology

    Transcriptional activator TAp63 is upregulated in muscular atrophy during ALS and induces the pro-atrophic ubiquitin ligase Trim63

    Yannick von Grabowiecki et al.
    Atrophic muscles of patients and animal models developing amyotrophic lateral sclerosis show an upregulation of TAp63 that stimulates the expression of a pro-atrophic ubiquitin ligase.
