    Rescue of cognitive function following fractionated brain irradiation in a novel preclinical glioma model

    Xi Feng et al.
    Whole-brain radiotherapy, but not glioma growth in distal region from the hippocampus, results in impaired recognition memory, which can be prevented by CSF-1R inhibitor-mediated microglia depletion.

    IRF4 haploinsufficiency in a family with Whipple’s disease

    Antoine Guérin et al.
    Autosomal dominant IRF4 deficiency is the first genetic etiology of Whipple's disease, a very rare chronic condition following a rather common infection by Tropheryma whipplei.

    O-GlcNAc on NOTCH1 EGF repeats regulates ligand-induced Notch signaling and vascular development in mammals

    Shogo Sawaguchi et al.
    The transfer of O-GlcNAc by EOGT to specific EGF repeats of NOTCH1 promotes DLL4 binding, Notch signaling, and retinal vascular development.

    Proteasome storage granules protect proteasomes from autophagic degradation upon carbon starvation

    Richard S Marshall, Richard D Vierstra
    Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.

    NFATc2 enhances tumor-initiating phenotypes through the NFATc2/SOX2/ALDH axis in lung adenocarcinoma

    Zhi-Jie Xiao et al.
    NFATc2 maintains the drug-induced TIC phenotypes through trans-activating SOX2/ALDH1A1 expression and scavenging stress from ROS.

    Biophysics of object segmentation in a collision-detecting neuron

    Richard Burkett Dewell, Fabrizio Gabbiani
    Active dendritic processing enables an individual neuron to discriminate the spatial pattern of synaptic inputs, increasing neural and behavioral selectivity for escaping an impending threat.

    Arcuate nucleus and lateral hypothalamic CART neurons in the mouse brain exert opposing effects on energy expenditure

    Aitak Farzi et al.
    CART exerts differential metabolic effects in response to activation of neurons of the Arc, where CART suppresses energy expenditure, while it enforces the reward characteristics of the LHA.

    Functional limb muscle innervation prior to cholinergic transmitter specification during early metamorphosis in Xenopus

    Francois M Lambert et al.
    Molecular labeling, electrophysiology and calcium imaging have revealed a novel switching of neurotransmitter at the frog neuromuscular junction where motoneurons transiently release glutamate before acetylcholine at synapses on developing hindlimb muscles at the onset of metamorphosis.

    Pro-death NMDA receptor signaling is promoted by the GluN2B C-terminus independently of Dapk1

    Jamie McQueen et al.
    Excitotoxicity driven by NMDA receptor hyper-activation does not involve DAPK1-dependent events in vitro or in vivo, and previously described DAPK1-NMDAR disrupting peptides act by blocking the NMDA receptor.

    Pioneer neurog1 expressing cells ingress into the otic epithelium and instruct neuronal specification

    Esteban Hoijman et al.
    Quantitative 4D image analysis identifies a group of cells which enter into the otic primordium during morphogenesis and instructs neuronal specification.
