    CAPS-1 promotes fusion competence of stationary dense-core vesicles in presynaptic terminals of mammalian neurons

    Margherita Farina, Rhea van de Bospoort ... Ruud F Toonen
    Stationary dense-core vesicles depend on the CAPS-1 protein to fuse with the presynaptic membrane.

    EphrinB2 drives perivascular invasion and proliferation of glioblastoma stem-like cells

    Benjamin Krusche, Cristina Ottone ... Simona Parrinello
    EphrinB2 promotes glioblastoma stem-like cell malignancy through the interplay of cell-autonomous and non-cell-autonomous mechanisms and its targeting suppresses tumourigenesis in preclinical models of human glioblastoma.

    A functional genomics screen in planarians reveals regulators of whole-brain regeneration

    Rachel H Roberts-Galbraith, John L Brubacher, Phillip A Newmark
    A gene expression-guided functional screen identifies factors and cell types that regulate diverse aspects of neural regeneration in planarians.

    Activity-dependent switch of GABAergic inhibition into glutamatergic excitation in astrocyte-neuron networks

    Gertrudis Perea, Ricardo Gómez ... Alfonso Araque
    Astrocytes decode temporal interneuron activity and transform inhibitory into excitatory signals that impact excitatory synaptic strength and neuronal circuit function.
    1. Neuroscience

    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.

    Cellular diversity in the Drosophila midbrain revealed by single-cell transcriptomics

    Vincent Croset, Christoph D Treiber, Scott Waddell
    Sequencing mRNA from thousands of single cells from the Drosophila brain highlights the extent of cellular diversity and reveals co-expression of specific neuropeptides with particular fast-acting neurotransmitters and monoamines.

    Ephrin-B3 controls excitatory synapse density through cell-cell competition for EphBs

    Nathan T Henderson, Sylvain J Le Marchand ... Matthew B Dalva
    Competition between neurons for postsynaptic ephrin-B3 controls distribution of a limited pool of synapses and defines a novel trans-synaptic mechanism enabling neurons to set the number of synapses they receive.

    Low wnt/β-catenin signaling determines leaky vessels in the subfornical organ and affects water homeostasis in mice

    Fabienne Benz, Viraya Wichitnaowarat ... Stefan Liebner
    Endothelial tightening by augmenting low level Wnt/β-catenin activity in vessels of the mouse subfornical organ, influences neuronal activation in water-deprived mice, linking endothelial barrier properties to neuro-vascular coupling.
    1. Neuroscience

    Astrocyte morphogenesis is dependent on BDNF signaling via astrocytic TrkB.T1

    Leanne M Holt, Raymundo D Hernandez ... Michelle L Olsen
    Brain-derived neurotrophic factor (BDNF)/TrkB.T1 signaling contributes to astrocyte morphological maturation, with implications for neuronal synaptogenesis and function and astrocyte functional maturation.
    1. Neuroscience

    Defined neuronal populations drive fatal phenotype in a mouse model of Leigh syndrome

    Irene Bolea, Alejandro Gella ... Albert Quintana
    Glutamatergic brainstem neurons drive motor and respiratory deficits, and GABAergic basal ganglia neurons cause hypothermia and fatal epileptic events, in a model of mitochondrial disease.
