    Architecture and structural dynamics of the heteromeric GluK2/K5 kainate receptor

    Nandish Khanra et al.
    Structures of the GluK2/K5 kainate receptor reveal the heteromer architecture and how the receptor organizes in apo, antagonist-bound, and desensitized states.

    Sushi domain-containing protein 4 controls synaptic plasticity and motor learning

    Inés González-Calvo et al.
    SUSD4 loss-of-function induces misregulation of GLUA2 degradation and of synaptic plasticity suggesting a mechanism for its potential contribution to neurodevelopmental disorders.

    Microglial trogocytosis and the complement system regulate axonal pruning in vivo

    Tony KY Lim, Edward S Ruthazer
    In vivo time lapse imaging reveals that microglial trogocytosis of presynaptic elements is regulated by the complement system which controls axon morphogenesis in the developing brain.

    Latrophilin GPCR signaling mediates synapse formation

    Richard Sando, Thomas C Südhof
    Spatial restriction of GPCR signaling at nascent synapses by adhesion complexes drives excitatory synapse formation and specificity in the hippocampus.

    Optogenetic control of PRC1 reveals its role in chromosome alignment on the spindle by overlap length-dependent forces

    Mihaela Jagrić et al.
    Optogenetic experiments show that bridging microtubules buffer chromosome movements and promote their alignment through forces transferred to the associated kinetochore fibers, which rely on precise regulation of the overlap region.

    SATB2 induction of a neural crest mesenchyme-like program drives melanoma invasion and drug resistance

    Maurizio Fazio et al.
    A genetic discovery screen for epigenetic factors accelerating melanoma development in vivo identifies SATB2 as a driver of tumor invasion and resistance to FDA-approved BRAF-targeted inhibitor Vemurafenib.

    Behavioral role of PACAP signaling reflects its selective distribution in glutamatergic and GABAergic neuronal subpopulations

    Limei Zhang et al.
    Placing the PACAP/PAC1 signaling within glutamate/GABA cell type and subregional contexts in mouse brain reveals its conspicuous role for sensorimotor circuit interaction through modulating neuronal plasticity.

    Dyshomeostatic modulation of Ca2+-activated K+ channels in a human neuronal model of KCNQ2 encephalopathy

    Dina Simkin et al.
    An inducedpluripotent stem cell (iPSC)-based model of KCNQ2-associated developmental epileptic encephalopathy suggests that disease is driven by dyshomeostaic neuronal mechanisms that are downstream of loss of M-current.

    Seizures are a druggable mechanistic link between TBI and subsequent tauopathy

    Hadeel Alyenbaawi et al.
    A traumatic brain injury model is invented for larval zebrafish and applied to a new fluorescent 'tauopathy reporter fish', revealing a role for seizures in progression towards dementias.
