    A novel monomeric amyloid β-activated signaling pathway regulates brain development via inhibition of microglia

    Hyo Jun Kwon, Devi Santhosh, Zhen Huang
    Molecular genetics identifies a novel microglial pathway essential for mouse brain development and a previously unknown anti-inflammatory activity of monomeric amyloid β that activates this pathway.

    Regionally distinct trophoblast regulate barrier function and invasion in the human placenta

    Bryan Marsh, Yan Zhou ... Robert Blelloch
    Single cell RNA-sequencing of distinct regions of the human placenta identifies a smooth chorion-specific cytotrophoblast population responsible for unique functions of the smooth chorion, including acting as a barrier and restricting invasion.

    Dual role for Jumu in the control of hematopoietic progenitors in the Drosophila lymph gland

    Yangguang Hao, Li Hua Jin
    Jumu is required for the proper differentiation of prohemocytes and the proliferation and location of PSC cells.

    The imprinted Zdbf2 gene finely tunes control of feeding and growth in neonates

    Juliane Glaser, Julian Iranzo ... Deborah Bourc'his
    Zdbf2 is a paternally expressed gene that is mainly expressed in the hypothalamus and promotes appetite and body weight gain in neonates.

    The pioneer factor OCT4 requires the chromatin remodeller BRG1 to support gene regulatory element function in mouse embryonic stem cells

    Hamish W King, Robert J Klose
    The chromatin remodeller BRG1 is recruited to pluripotency-associated gene regulatory elements by the pioneer transcription factor OCT4 to support further transcription factor binding and gene regulation.

    Reorganization of postmitotic neuronal chromatin accessibility for maturation of serotonergic identity

    Xinrui L Zhang, William C Spencer ... Evan S Deneris
    Terminal selectors reorganize postmitotic neuronal chromatin to select cis-regulatory elements during 5-HT neuron maturation.

    Multiple motors cooperate to establish and maintain acentrosomal spindle bipolarity in C. elegans oocyte meiosis

    Gabriel Cavin-Meza, Michelle M Kwan, Sarah M Wignall
    Rapid depletion of dynein from oocytes yielded new insights into acentrosomal pole organization and also led to the first evidence that the kinesin-5 motor BMK-1 plays a role in microtubule organization during C. elegans meiosis.

    High hedgehog signaling is transduced by a multikinase-dependent switch controlling the apico-basal distribution of the GPCR smoothened

    Marina Gonçalves Antunes, Matthieu Sanial ... Isabelle Becam
    Hedgehog leads to Smoothened accumulation by favoring its recycling and high Hedgehog levels promote a basolateral enrichment of Smoothened via its phosphorylation by the protein kinase Fused.

    A physicochemical perspective of aging from single-cell analysis of pH, macromolecular and organellar crowding in yeast

    Sara N Mouton, David J Thaller ... Liesbeth M Veenhoff
    In mitotically aging yeast cells, the cytosol acidifies, the distances between the organellar membranes decrease dramatically, but crowding on the scale of the average size protein is relatively stable.

    Optical mapping of ground reaction force dynamics in freely behaving Drosophila melanogaster larvae

    Jonathan H Booth, Andrew T Meek ... Malte C Gather
    A new optical approach reveals dynamics of ground reaction forces in Drosophila larvae and opens new avenues for studying the biomechanics of movement in small animals.
