    1. Neuroscience

    Associative learning drives longitudinally graded presynaptic plasticity of neurotransmitter release along axonal compartments

    Aaron Stahl, Nathaniel C Noyes ... Seth M Tomchik
    Experience alters neurotransmitter release from different axonal compartments in different ways, allowing a set of neurons to coherently modulate behavior through diverse actions on multiple downstream circuits.

    EHD2 overexpression promotes tumorigenesis and metastasis in triple-negative breast cancer by regulating store-operated calcium entry

    Haitao Luan, Timothy A Bielecki ... Hamid Band
    Identification of a pro-tumorigenic and pro-metastatic role of EHD2 protein in triple-negative breast cancer (TNBC) through the store-operated calcium entry (SOCE) pathway provides a rationale for potential targeting of EHD2-overexpressing TNBC with SOCE inhibitors.

    Testing the ion-current model for flagellar length sensing and IFT regulation

    Hiroaki Ishikawa, Jeremy Moore ... Wallace F Marshall
    A model for flagellar length control based on calcium influx is rejected based on quantitative measurements in Chlamydomonas cells.

    A potent voltage-gated calcium channel inhibitor engineered from a nanobody targeted to auxiliary CaVβ subunits

    Travis J Morgenstern, Jinseo Park ... Henry M Colecraft
    A novel engineered protein that uncouples electrical signals from downstream biological responses in excitable cells provides a unique investigative tool with potential therapeutic applications.
    1. Neuroscience

    Age-associated changes to neuronal dynamics involve a disruption of excitatory/inhibitory balance in C. elegans

    Gregory S Wirak, Jeremy Florman ... Christopher V Gabel
    Comprehensive multi-neuron fluorescence imaging in C. elegans reveals age-associated changes in neuronal activity that include a breakdown of system-wide organization, changes in neuronal frequency dynamics, and a disruption of the balance between excitatory and inhibitory signaling.
    1. Neuroscience

    The DEG/ENaC cation channel protein UNC-8 drives activity-dependent synapse removal in remodeling GABAergic neurons

    Tyne W Miller-Fleming, Sarah C Petersen ... David M Miller III
    The protein UNC-8 is a neuronal activity sensor that triggers the elimination of synapses during development of the nervous system.
    1. Neuroscience

    Elucidating a locus coeruleus-dentate gyrus dopamine pathway for operant reinforcement

    Elijah A Petter, Isabella P Fallon ... Henry H Yin
    Mice can learn to press a lever persistently for activation of a dopaminergic projection from the locus coeruleus to the hippocampal dentate gyrus.
    1. Neuroscience

    The integration of Gaussian noise by long-range amygdala inputs in frontal circuit promotes fear learning in mice

    Mattia Aime, Elisabete Augusto ... Frederic Gambino
    The frontal associative cortex promotes fear learning by non-linearly integrating Gaussian noise in between conditioning trials with the help of basolateral amygdala inputs.
    1. Neuroscience

    Maintenance of homeostatic plasticity at the Drosophila neuromuscular synapse requires continuous IP3-directed signaling

    Thomas D James, Danielle J Zwiefelhofer, C Andrew Frank
    Synapses employ distinct acute and chronic signaling processes in order to maintain physiologically appropriate levels of function.
