    Machine learning approaches identify immunologic signatures of total and intact HIV DNA during long-term antiretroviral therapy

    Lesia Semenova, Yingfan Wang ... Edward P Browne
    Dimension reduction and machine learning tools were used to identify novel associations between the HIV reservoir and the immune systems of people with HIV.

    A quantitative framework for whole-body coordination reveals specific deficits in freely walking ataxic mice

    Ana S Machado, Dana M Darmohray ... Megan R Carey
    Analysis of 3D paw kinematics and whole-body coordination in freely walking mice isolates specific features of gait ataxia and supports the hypothesis that the cerebellum provides an internal forward model for motor control.

    Genome-wide alterations of uracil distribution patterns in human DNA upon chemotherapeutic treatments

    Hajnalka L Pálinkás, Angéla Békési ... Beáta G Vértessy
    Human genomic DNA contains uracil in the late replicating, constitutive heterochromatic regions, while treatment with drugs perturbing thymidylate biosynthesis shifts the uracil distribution pattern towards the euchromatin in UNG-inhibited cells.

    Motor cortex analogue neurons in songbirds utilize Kv3 channels to generate ultranarrow spikes

    Benjamin M Zemel, Alexander A Nevue ... Henrique von Gersdorff
    Molecular and electrophysiological evidence shows that Kv3 subunits contribute critically to ultrashort action potential waveforms and high-frequency firing in large projection neurons in zebra finch motor nuclei controlling song production and somatic movements.

    T cell deficiency precipitates antibody evasion and emergence of neurovirulent polyomavirus

    Matthew D Lauver, Ge Jin ... Aron E Lukacher
    Loss of T cell control during persistent polyomavirus infection, in the setting of a limited antiviral antibody response, facilitates emergence of antibody-escape viruses carrying the potential for neurovirulence.

    Continuous odor profile monitoring to study olfactory navigation in small animals

    Kevin S Chen, Rui Wu ... Andrew M Leifer
    To study odor-guided navigation of small animals such as worms and fly larvae, a novel flow chamber and odor sensor array are presented that better characterize the odors that the animal experiences.

    CryoEM and computer simulations reveal a novel kinase conformational switch in bacterial chemotaxis signaling

    C Keith Cassidy, Benjamin A Himes ... Peijun Zhang
    An atomic model of the bacterial chemosensory array obtained through the synthesis of cryo-electron tomography and large-scale molecular-dynamics simulations reveals a new kinase conformation during signaling events.

    Visually induced changes in cytokine production in the chick choroid

    Jody A Summers, Elizabeth Martinez
    IL-6 gene and protein expression are rapidly and transiently upregulated in the choroid in response to myopic defocus, as a result of prior form deprivation or treatment with +15 D lenses in a nitric oxide-dependent manner.

    An optimal regulation of fluxes dictates microbial growth in and out of steady state

    Griffin Chure, Jonas Cremer
    Microbial cells optimally structure their proteomes in order to mutually maximize metabolism and translation, as established by an extensive comparison between data and a low-dimensional model of cellular physiology.

    Amoeboid-like migration ensures correct horizontal cell layer formation in the developing vertebrate retina

    Rana Amini, Archit Bhatnagar ... Caren Norden
    Horizontal cell undergoes amoeboid-like migration in the developing vertebrate retina, a not previously reported migration mode in the central nervous system, that allows them to move within a densely packed tissue without predetermined paths.
