    Cohesin architecture and clustering in vivo

    Siheng Xiang, Douglas Koshland
    Cohesin adopts a flexible butterfly conformation in vivo and forms spatial and temporal regulated ordered clusters to maintain cohesion and condensation.

    Operation regimes of spinal circuits controlling locomotion and the role of supraspinal drives and sensory feedback

    Ilya A Rybak, Natalia A Shevtsova ... Alain Frigon
    Spinal circuits performing speed- and context-dependent control of locomotion in mammals can operate in different regimes with prevailing role of central mechanisms, supraspinal signals, or sensory feedback.
  1. Meta-Research: Questionable research practices may have little effect on replicability

    Rolf Ulrich, Jeff Miller
    Although questionable research practices inflate false positive rates, they have little effect on replicability because they also increase power.

    A Brownian ratchet model for DNA loop extrusion by the cohesin complex

    Torahiko L Higashi, Georgii Pobegalov ... Frank Uhlmann
    A structure-based model of the chromosomal cohesin complex, accompanied by molecular-mechanistic simulations, explains cohesin's key role in topologically entrapping DNA, as well as its ability to alternatively extrude DNA loops.

    Pruriception and neuronal coding in nociceptor subtypes in human and nonhuman primates

    Amanda Klein, Hans Jürgen Solinski ... Matthias Ringkamp
    MRGPRD and MRGRPX1 are co-expressed in primate DRG neurons, but β-alanine and BAM8-22, preferentially activate CMH-subclasses, and co-activating different cutaneous nociceptors by pruritogens does not change itch sensation to pain.

    Vision: Running into differences

    Eleni Psarou, Shivangi Patel, Marieke Schölvinck
    Body movement does not significantly increase neuronal activity in the primary visual cortex of marmosets, in contrast to the effects observed in mice.

    Contribution of dorsal horn CGRP-expressing interneurons to mechanical sensitivity

    Line S Löken, Joao M Braz ... Allan Basbaum
    Although primary sensory neuron-derived calcitonin gene-related peptide (CGRP) contributes to the processing of pain messages, an understudied population of dorsal horn CGRP-expressing interneurons also contributes to the processing of mechanical sensitivity.

    Distinct impact of IgG subclass on autoantibody pathogenicity in different IgG4-mediated diseases

    Yanxia Bi, Jian Su ... Fubin Li
    The IgG4 subclass, previously considered anti-inflammatory due to its weak effector function, could either reduce or exacerbate autoantibody pathogenicity in the context of different IgG4-mediated autoimmune diseases.

    Development and characterization of a chronic implant mouse model for vagus nerve stimulation

    Ibrahim T Mughrabi, Jordan Hickman ... Stavros Zanos
    Long-term, dose-controlled vagus nerve stimulation (VNS) is feasible in mice using a multi-lab validated implantation procedure, allowing therapeutic testing of VNS in many disease models.

    Transient inhibition and long-term facilitation of locomotion by phasic optogenetic activation of serotonin neurons

    Patrícia A Correia, Eran Lottem ... Zachary F Mainen
    Phasic activation of dorsal raphe serotonin neurons transiently inhibits locomotion without influencing anxiety or producing reinforcement, but when repeated over many days a long-term facilitation of locomotion is produced.
