    Hippocampal and cortical mechanisms at retrieval explain variability in episodic remembering in older adults

    Alexandra N Trelle, Valerie A Carr ... Anthony D Wagner
    The strength of pattern completion during memory retrieval, indexed by hippocampal activity and cortical reinstatement, explains within- and across-individual variability in episodic memory in older adults.

    Lin28a/let-7 pathway modulates the Hox code via Polycomb regulation during axial patterning in vertebrates

    Tempei Sato, Kensuke Kataoka ... Hiroshi Asahara
    Genetic analyses reveal that the loss of Lin28a causes axial shortening with mild skeletal transformations via decreased PRC1 at Hox genes, establishing a new pathway in the “Hox code.”.

    Single-cell transcriptome reveals the novel role of T-bet in suppressing the immature NK gene signature

    Chao Yang, Jason R Siebert ... Subramaniam Malarkannan
    T-bet suppresses the expression of immature NK cell-defining genes.

    Principles of operation of a cerebellar learning circuit

    David J Herzfeld, Nathan J Hall ... Stephen G Lisberger
    Quantitative analysis of behavior coupled with computational modeling reveal the set of circuit-level principles that underlie cerebellar-dependent motor learning in smooth pursuit eye movements of monkeys across timescales.

    A tudor domain protein, SIMR-1, promotes siRNA production at piRNA-targeted mRNAs in C. elegans

    Kevin I Manage, Alicia K Rogers ... Carolyn Marie Phillips
    SIMR-1 acts downstream of the piRNA pathway to promote siRNA amplification by the Mutator complex and localizes to perinuclear foci distinct from Mutator foci, P granules and Z granules.

    Effects of fluorescent glutamate indicators on neurotransmitter diffusion and uptake

    Moritz Armbruster, Chris G Dulla, Jeffrey S Diamond
    Fluorescent glutamate indicators distort the time course of neurotransmitter diffusion and uptake by competing with transporters, an important caveat to consider when using iGluSnFR and its analogs.

    TUBB4A mutations result in both glial and neuronal degeneration in an H-ABC leukodystrophy mouse model

    Sunetra Sase, Akshata A Almad ... Adeline Vanderver
    H-ABC leukodystrophy results in neurologic decline, hypomyelination and atrophy of the striatum and cerebellum and Tubb4aD249N/D249Nmouse model recapitulates features of H-ABC disease, providing an important tool for therapeutic development.

    Distinct mitochondrial defects trigger the integrated stress response depending on the metabolic state of the cell

    Eran Mick, Denis V Titov ... Vamsi K Mootha
    Mitochondrial electron transport chain dysfunction triggers the integrated stress response due to an asparagine deficiency downstream of impaired NADH oxidation in proliferating myoblasts, but not in differentiated myotubes.

    Identifying the immune interactions underlying HLA class I disease associations

    Bisrat J Debebe, Lies Boelen ... Becca Asquith
    HLA class I-disease associations have been studied for decades; a new approach for investigating the underlying mechanism can overcome past problems with interpretation and help to understand the etiology of human diseases.

    A CLC-ec1 mutant reveals global conformational change and suggests a unifying mechanism for the CLC Cl/H+ transport cycle

    Tanmay S Chavan, Ricky C Cheng ... Merritt Maduke
    Crystallography together with electron-resonance spectroscopy, molecular-dynamics simulations, and transport measurements reveal the molecular details of protein conformational change, and how this change contributes to function in a CLC-type chloride/proton exchanger.
