    Pathogenic LRRK2 control of primary cilia and Hedgehog signaling in neurons and astrocytes of mouse brain

    Shahzad S Khan, Yuriko Sobu ... Suzanne R Pfeffer
    Striatal cholinergic interneurons and astrocytes lose cilia and show dysregulation of Hedgehog signaling in mice with a Parkinson's disease-associated, G2019S LRRK2 mutation or upon loss of PPM1H phosphatase specific for LRRK2-phosphorylated Rab GTPases.

    Acute stress enhances adult rat hippocampal neurogenesis and activation of newborn neurons via secreted astrocytic FGF2

    Elizabeth D Kirby, Sandra E Muroy ... Daniela Kaufer
    Exposing rats to acute stress increased the generation of new neurons in a subregion of the hippocampus, and improved the animals' performance in a memory task two weeks later.

    Early-life stress induces persistent astrocyte dysfunction associated with fear generalisation

    Mathias Guayasamin, Lewis R Depaauw-Holt ... Ciaran Murphy-Royal
    Amygdala astrocytes play a critical role in mediating the effects of stress during infancy on neuronal excitability, synaptic plasticity, and memory.

    A spatial threshold for astrocyte calcium surge

    Justin Lines, Andres Baraibar ... Alfonso Araque
    In astrocytes, there exists an intrinsic spatial threshold of subcellular calcium levels that triggers an astrocyte calcium surge throughout the cell, demonstrating cellular astrocyte calcium integration of time and space.

    TrpML-mediated astrocyte microdomain Ca2+ transients regulate astrocyte–tracheal interactions

    Zhiguo Ma, Marc R Freeman
    Astrocyte microdomain calcium transients are mediated by TrpML, stimulated by ROS and tyramine, and mediate astrocyte–tracheal interactions in CNS gas exchange.

    Astrocyte morphology is confined by cortical functional boundaries in mammals ranging from mice to human

    Raya Eilam, Rina Aharoni ... Rafael Malach
    The structural morphology of astrocyte processes is constrained by functional boundaries in the mouse, rat and human cortex.

    Astrocyte GluN2C NMDA receptors control basal synaptic strengths of hippocampal CA1 pyramidal neurons in the stratum radiatum

    Peter H Chipman, Chi Chung Alan Fung ... Yukiko Goda
    Electrophysiology experiments with genetic and pharmacological manipulations identify a role for astrocyte GluN2C NMDA receptors in maintaining the broad range of presynaptic strengths, which is suggested by numerical simulations to enhance the expression of synaptic plasticity.

    Upregulated expression of ubiquitin ligase TRIM21 promotes PKM2 nuclear translocation and astrocyte activation in experimental autoimmune encephalomyelitis

    Luting Yang, Chunqing Hu ... Yaping Yan
    Cell biology and animal model analysis in mice shows that molecules involved in glycolytic metabolism could potentially serve as therapeutic targets for the treatment of neurological diseases.

    Astrocytes mediate two forms of spike timing-dependent depression at entorhinal cortex-hippocampal synapses

    Irene Martínez-Gallego, Heriberto Coatl-Cuaya, Antonio Rodriguez-Moreno
    Two different forms of brain plasticity require astrocytes and show different action mechanisms at enthorrinal cortex hippocampal synapses.

    SRF-deficient astrocytes provide neuroprotection in mouse models of excitotoxicity and neurodegeneration

    Surya Chandra Rao Thumu, Monika Jain ... Narendrakumar Ramanan
    Serum response factor (SRF) deficient reactive astrocytes are neuroprotective in the mammalian brain.
