    Alterations in the intrinsic properties of striatal cholinergic interneurons after dopamine lesion and chronic L-DOPA

    Se Joon Choi, Thong C Ma ... Un Jung Kang
    HCN and SK channel currents in striatal cholinergic neurons are decreased with dopamine loss, but only HCN is restored by chronic L-DOPA and SK abnormality persists in dyskinesia.

    Periodic propagating waves coordinate RhoGTPase network dynamics at the leading and trailing edges during cell migration

    Alfonso Bolado-Carrancio, Oleksii S Rukhlenko ... Boris N Kholodenko
    Different RhoA and Rac1 dynamics at the cell front and rear are coordinated through periodic GTPase waves, which define the minimal autonomous biochemical machinery necessary and sufficient for cell migration.

    Late-life restoration of mitochondrial function reverses cardiac dysfunction in old mice

    Ying Ann Chiao, Huiliang Zhang ... Peter Rabinovitch
    Mitochondrial-targeted SS-31 peptide ameliorates mitochondrial dysfunction and rescues pre-existing cardiac dysfunction in old mice, supporting the translational potential of mitochondrial protective interventions to treat age-related diseases.

    Miga-mediated endoplasmic reticulum–mitochondria contact sites regulate neuronal homeostasis

    Lingna Xu, Xi Wang ... Chao Tong
    Increasing endoplasmic reticulum (ER)–mitochondria contact sites leads to neurodegeneration.

    Private–public mappings in human prefrontal cortex

    Dan Bang, Sara Ershadmanesh ... Stephen M Fleming
    A distinction between private and public aspects of mental states is reflected in a medial-lateral division of human prefrontal cortex.

    Altered expression of a quality control protease in E. coli reshapes the in vivo mutational landscape of a model enzyme

    Samuel Thompson, Yang Zhang ... Tanja Kortemme
    Changes to cellular protein homeostasis reveal widespread advantageous effects of destabilizing mutations, opening the possibility to switch mutational landscapes back-and-forth from permissive to restrictive.

    3,6’-dithiopomalidomide reduces neural loss, inflammation, behavioral deficits in brain injury and microglial activation

    Chih-Tung Lin, Daniela Lecca ... Nigel H Greig
    The new drug 3,6’-dithiopomalidomide mitigates key markers of neuronal death and neuroinflammation and improves acute behavioral outcome measures in traumatic brain injury, a common, debilitating disorder that lacks effective treatment.

    An adipokine feedback regulating diurnal food intake rhythms in mice

    Anthony H Tsang, Christiane E Koch ... Henrik Oster
    Adiponectin signaling integrates metabolic state information to regulate circadian clock function in hypothalamic appetite regulating centers, food intake rhythms, and body weight.

    Growth cone-localized microtubule organizing center establishes microtubule orientation in dendrites

    Xing Liang, Marcela Kokes ... Kang Shen
    In Caenorhabditis elegans, dendrites establish their unique microtubule polarity by localizing an organizing center behind the growing tip.

    Inhibition of post-termination ribosome recycling at premature termination codons in UPF1 ATPase mutants

    Lucas D Serdar, DaJuan L Whiteside ... Kristian E Baker
    Nucleotide resolution mapping of ribosome-bound RNA decay fragments in yeast cells expressing ATPase-deficient UPF1 reveals 3' UTR bound ribosomes and a role for UPF1 in post-termination ribosome recycling.
