    Lactate is an energy substrate for rodent cortical neurons and enhances their firing activity

    Anastassios Karagiannis, Thierry Gallopin ... Bruno Cauli
    Lactate is preferred to glucose as an energy substrate and exacerbates spiking activity in most neuron types of juvenile somatosensory cortex by closing ATP-sensitive potassium channels.

    Axonal T3 uptake and transport can trigger thyroid hormone signaling in the brain

    Federico Salas-Lucia, Csaba Fekete ... Antonio C Bianco
    T3 is taken up by axonal termini and is retrogradely transported into endosomal vesicles to the cell nucleus, where it regulates gene expression.

    Paradoxical neuronal hyperexcitability in a mouse model of mitochondrial pyruvate import deficiency

    Andres De La Rossa, Marine H Laporte ... Jean-Claude Martinou
    Glutamatergic neurons lacking the mitochondrial pyruvate carrier show reduced M-type potassium channel activity and hyperexcitability upon intense firing.

    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.

    Switching of RNA splicing regulators in immature neuroblasts during adult neurogenesis

    Corentin Bernou, Marc-André Mouthon ... François Dominique Boussin
    Characterization of an abundant clonogenic and multipotent population of immature neuroblasts, at the transition between transient-amplifying progenitor (TAP) neuroblasts and migratory neuroblasts, reversibly engaged in neuronal differentiation.

    Regulation of nerve growth and patterning by cell surface protein disulphide isomerase

    Geoffrey MW Cook, Catia Sousa ... Roger J Keynes
    The nerve growth-repellent activity that generates spinal nerve repeat-patterning in birds and mammals is identified at the molecular level, and a similar system is revealed in adult brain grey matter.

    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. Developmental Biology

    MCT1-dependent energetic failure and neuroinflammation underlie optic nerve degeneration in Wolfram syndrome mice

    Greta Rossi, Gabriele Ordazzo ... Vania Broccoli
    The endoplasmic reticulum (ER)-resident protein wolframin regulates MCT1 protein levels in retinal glial cells controlling the shuttling of energy metabolites to both somata and axons of retinal ganglion cells and, thus, supporting their fitness and survival.
