    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.

    Von Willebrand factor A1 domain stability and affinity for GPIbα are differentially regulated by its O-glycosylated N- and C-linker

    Klaus Bonazza, Roxana E Iacob ... Timothy A Springer
    Both the polypeptide and attached O-glycans N-terminal to the A1 domain in von Willebrand factor lower its affinity for its ligand GPIbα on platelets, its stability, and structural dynamics and decrease population of a high-affinity, intermediate state in unfolding.

    Oxytocin neurons mediate the effect of social isolation via the VTA circuits

    Stefano Musardo, Alessandro Contestabile ... Camilla Bellone
    Oxytocin neurons in the paraventricular nucleus of the hypothalamus mediate the increased sociability as a consequence of acute social isolation during adolescence via ventral tegmental area circuits.

    Parent-of-origin effects propagate through networks to shape metabolic traits

    Juan F Macias-Velasco, Celine L St Pierre ... Heather A Lawson
    Non-imprinted genes can contribute to parent-of-origin effects on phenotype through interactions with imprinted genes.

    Distinct representations of body and head motion are dynamically encoded by Purkinje cell populations in the macaque cerebellum

    Omid A Zobeiri, Kathleen E Cullen
    The transformation of multiple streams of sensory information into an estimate of body motion occurs between the cerebellum and deep cerebellar nucleus to ensure postural and perceptual stability.

    Cerebellum encodes and influences the initiation, performance, and termination of discontinuous movements in mice

    Michael A Gaffield, Britton A Sauerbrei, Jason M Christie
    The activity of cerebellar Purkinje cells both represents and participates in organizing the temporal structure of a periodically performed motor action.

    Intracellular glycosyl hydrolase PslG shapes bacterial cell fate, signaling, and the biofilm development of Pseudomonas aeruginosa

    Jingchao Zhang, Huijun Wu ... Luyan Ma
    A systematical study of pslG mutants at both a single cell and community level reveals the importance of intracellular glycosyl hydrolase PslG on the cell fate and biofilm development of P. aeruginosa, an opportunistic pathogen that can cause persistent infections.

    Wnt11 acts on dermomyotome cells to guide epaxial myotome morphogenesis

    Ann Kathrin Heilig, Ryohei Nakamura ... Toru Kawanishi
    A medaka mutant revealed that Wnt11 promotes formation of uniquely large protrusions from non-myogenic dorsal dermomyotome cells, which guide the epaxial myotome dorsally to achieve the coverage of the neural tube.

    Flexible utilization of spatial- and motor-based codes for the storage of visuo-spatial information

    Margaret M Henderson, Rosanne L Rademaker, John T Serences
    When human participants are able to plan responses in a visuo-spatial working memory task, sensory-like representations of remembered spatial position in early visual and parietal cortex adaptively trade off with motor-like representations of upcoming actions in sensorimotor cortex.

    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.
