    A bidirectional switch in the Shank3 phosphorylation state biases synapses toward up- or downscaling

    Chi-Hong Wu, Vedakumar Tatavarty ... Gina G Turrigiano
    Activity-dependent bidirectional changes in phosphorylation of the autism-associated scaffold protein Shank3 are essential for the expression of homeostatic synaptic plasticity.

    MDGAs are fast-diffusing molecules that delay excitatory synapse development by altering neuroligin behavior

    Andrea Toledo, Mathieu Letellier ... Olivier Thoumine
    MDGAs are highly diffusive molecules that alter both neuroligin-1 and AMPA receptor dynamics and function, thereby significantly delaying the differentiation of excitatory post-synapses.

    Microtubule assembly by tau impairs endocytosis and neurotransmission via dynamin sequestration in Alzheimer’s disease synapse model

    Tetsuya Hori, Kohgaku Eguchi ... Tomoyuki Takahashi
    Wild-type human recombinant tau protein infused in presynaptic terminals newly assembled microtubules, which sequestered cytosolic dynamins, thereby blocking synaptic vesicle endocytosis and causing activity-dependent rundown of excitatory synaptic transmission in a slice model of mouse brainstem.

    Oligogenic heterozygous inheritance of sperm abnormalities in mouse

    Guillaume Martinez, Charles Coutton ... Christophe Arnoult
    This first evidence of oligogenic inheritance in failed spermatogenesis strongly suggests that oligogenic heterozygosity could explain a significant proportion of asthenoteratozoospermia cases.

    Enhanced C/EBPβ function promotes hyperplastic versus hypertrophic fat tissue growth and prevents steatosis in response to high-fat diet feeding

    Christine Müller, Laura M Zidek ... Cornelis F Calkhoven
    Gene regulation by C/EBPβ determines how surplus of dietary fat is stored, which has consequences for metabolic health.

    Crotamiton derivative JM03 extends lifespan and improves oxidative and hypertonic stress resistance in Caenorhabditis elegans via inhibiting OSM-9

    Keting Bao, Wenwen Liu ... Jian Li
    In a chemical genetics study, JM03 derived from crotamiton, an inhibitor of trainsient receptor potential vanilloid-4 channels, was identified to extend lifespan and improve oxidative and hypertonic stress resistance in Caenorhabditis elegans via inhibiting OSM-9.

    Retinoic acid-induced protein 14 controls dendritic spine dynamics associated with depressive-like behaviors

    Soo Jeong Kim, Youngsik Woo ... Sang Ki Park
    Rai14-Tara complex enhances the stability of dendritic spines and synaptic connections relevant to depressive-like behaviors.

    Condensation of Ede1 promotes the initiation of endocytosis

    Mateusz Kozak, Marko Kaksonen
    Protein phase separation provides an explanation for the compositional flexibility of endocytic initiation and the role of multivalent disordered scaffolds in endocytosis.

    A tRNA processing enzyme is a key regulator of the mitochondrial unfolded protein response

    James P Held, Gaomin Feng ... Maulik R Patel
    A key role for RNAs in sensing and mounting a response to mitochondrial stress.

    Long-range migration of centrioles to the apical surface of the olfactory epithelium

    Kaitlin Ching, Jennifer T Wang, Tim Stearns
    Olfactory sensory neurons have centrioles that are amplified in number and that migrate from the cell body to the end of the dendrite relatively slowly and in groups, becoming mature only after they reach their destination.
