    The Reissner fiber under tension in vivo shows dynamic interaction with ciliated cells contacting the cerebrospinal fluid

    Celine Bellegarda, Guillaume Zavard ... Claire Wyart
    Experimental manipulations and a mechanical model of the fiber reveal that the Reissner fiber is under heterogenous tension in vivo, and interacts with the motile cilia of diverse cells contacting the cerebrospinal fluid.

    A class-specific effect of dysmyelination on the excitability of hippocampal interneurons

    Delphine Pinatel, Edouard Pearlstein ... Catherine Faivre-Sarrailh
    Dysmyelination of GABAergic hippocampal interneurons causes mislocalization of axonal ionic channels and disturbs their intrinsic physiological properties, suggesting that it may contribute to cognitive deficits observed in multiple sclerosis patients.

    Diversity and evolution of cerebellar folding in mammals

    Katja Heuer, Nicolas Traut ... Roberto Toro
    A computational neuroanatomy analysis of cerebellar and cerebral folding in 56 mammalian species reveals groups of highly variable 'diverse' phenotypes, and strongly conserved 'stable' phenotypes, providing new insights into the diversity, evolution, and influence of cortical folding on brain organisation.

    Replisome loading reduces chromatin motion independent of DNA synthesis

    Maruthi Kumar Pabba, Christian Ritter ... M Cristina Cardoso
    Live cell tracking of labeled DNA reveals that replisome loading rather than DNA synthesis decreases the chromatin motion during S-phase in human cells.

    Energy coupling and stoichiometry of Zn2+/H+ antiport by the prokaryotic cation diffusion facilitator YiiP

    Adel Hussein, Shujie Fan ... David L Stokes
    Cryo-EM, Molecular Dynamics, and in vitro binding assays are combined to elucidate a new occluded conformation associated with zinc binding and energy coupling with the proton motive force.

    CCR1 mediates Müller cell activation and photoreceptor cell death in macular and retinal degeneration

    Sarah Elbaz-Hayoun, Batya Rinsky ... Itay Chowers
    A novel therapy for a common blinding retinal disease uses an innovative CCR1 blocking-based strategy.

    The PMA phorbol ester tumor promoter increases canonical Wnt signaling via macropinocytosis

    Nydia Tejeda-Munoz, Yagmur Azbazdar ... Edward M De Robertis
    The archetypal tumor promoter PMA, which promotes cancer without mutating the DNA, increases Wnt signaling by activating macropinocytosis and membrane trafficking in Xenopus embryos and tumor cells.

    Hepatic conversion of acetyl-CoA to acetate plays crucial roles in energy stress

    Jinyang Wang, Yaxin Wen ... Qinxi Li
    Acetate concentration, which is significantly increased in association with energy stresses such as those that occur with diabetes or starvation, is emerging as a novel 'ketone body' with potential as a parameter for evaluating the progression of energy stress.

    Sexual dimorphic regulation of recombination by the synaptonemal complex in C. elegans

    Cori K Cahoon, Colette M Richter ... Diana E Libuda
    Developing eggs and sperm differentially regulate specific steps of meiotic DNA repair by altering the composition and dynamics of proteins within synaptonemal complex.

    Methylglyoxal-derived hydroimidazolone, MG-H1, increases food intake by altering tyramine signaling via the GATA transcription factor ELT-3 in Caenorhabditis elegans

    Muniesh Muthaiyan Shanmugam, Jyotiska Chaudhuri ... Pankaj Kapahi
    Advanced glycation end-products (compounds which make the food appetizing and aromatic) intricately modulate organism’s homeostatic and hedonistic signaling pathways thereby inducing preferential consumption of excess nutrients offering preliminary insights into overconsumption of modern-day processed food.
