    Group III metabotropic glutamate receptors gate long-term potentiation and synaptic tagging/capture in rat hippocampal area CA2

    Ananya Dasgupta, Yu Jia Lim ... Sreedharan Sajikumar
    Group III metabotropic glutamate receptor inhibition facilitates synaptic plasticity in the plasticity-resistant synapses of hippocampal area CA2, a brain region critical for social memory.

    Retromer subunit, VPS29, regulates synaptic transmission and is required for endolysosomal function in the aging brain

    Hui Ye, Shamsideen A Ojelade ... Joshua M Shulman
    Vps29 promotes retromer localization in the adult Drosophila brain, engaging Rab7 and TBC1D5, and its loss triggers age-dependent neuronal impairments in endolysosomal trafficking and synaptic transmission.

    Learning induces the translin/trax RNase complex to express activin receptors for persistent memory

    Alan Jung Park, Robbert Havekes ... Ted Abel
    Combination of in vitro and in vivo approaches reveal how learning suppresses the microRNA system to trigger de novo synthesis of plasticity proteins, a missing link in the current model of microRNA-mediated translation in persistent synaptic plasticity and memory.

    Tau and spectraplakins promote synapse formation and maintenance through Jun kinase and neuronal trafficking

    Andre Voelzmann, Pilar Okenve-Ramos ... Natalia Sanchez-Soriano
    A novel regulatory cascade downstream of Tau and spectraplakins ensures that synaptic proteins are delivered to axonal terminals in the developing and ageing brain, providing potential explanations for precocious synapse loss in dementias.

    Dynamics and nanoscale organization of the postsynaptic endocytic zone at excitatory synapses

    Lisa AE Catsburg, Manon Westra ... Harold D MacGillavry
    The postsynaptic endocytic zone is a highly organized structure composed of a diversity of endocytic proteins.

    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.
    1. Neuroscience

    Multiple conserved cell adhesion protein interactions mediate neural wiring of a sensory circuit in C. elegans

    Byunghyuk Kim, Scott W Emmons
    The formation of neuronal connectivity of a C. elegans neuron pair is promoted by multiplexed interactions of neural cell adhesion proteins, which are evolutionarily conserved across animal taxa.

    Initial elevations in glutamate and dopamine neurotransmission decline with age, as does exploratory behavior, in LRRK2 G2019S knock-in mice

    Mattia Volta, Dayne A Beccano-Kelly ... Austen J Milnerwood
    LRRK2 G2019S knock-in mice are a genetically faithful model that recapitulates the slow disease progression of familial PD, with initial alterations to behaviour and neurotransmission providing early pathophysiological targets for neuroprotective interventions.

    Murine muscle stem cell response to perturbations of the neuromuscular junction are attenuated with aging

    Jacqueline A Larouche, Mahir Mohiuddin ... Carlos A Aguilar
    Muscle stem cells locally respond to perturbations of motor neurons and the neuromuscular junction.
