    Homeostatic regulation of perisynaptic matrix metalloproteinase 9 (MMP9) activity in the amblyopic visual cortex

    Sachiko Murase, Dan Winkowski ... Elizabeth M Quinlan
    Dark exposure lowers the MMP9 activation threshold, and subsequent light stimulation to an amblyopic eye is sufficient to induce proteolysis at thalamo-cortical synapses in deprived mouse visual cortex.

    Two new polymorphic structures of human full-length alpha-synuclein fibrils solved by cryo-electron microscopy

    Ricardo Guerrero-Ferreira, Nicholas MI Taylor ... Henning Stahlberg
    Two new polymorphic structures of recombinant human alpha-synuclein fibrils show striking differences to previous structures, while familial PD mutation sites remain crucial for protofilament interaction and fibril stability.

    The Fml1-MHF complex suppresses inter-fork strand annealing in fission yeast

    Io Nam Wong, Jacqueline PS Neo ... Matthew C Whitby
    Genomic deletions formed from inter-fork strand annealing associated with a collapsed replication fork are suppressed by the FANCM-related DNA helicase Fml1 in conjunction with its partner proteins Mhf1 and Mhf2.

    A genome-wide view of the de-differentiation of central nervous system endothelial cells in culture

    Mark F Sabbagh, Jeremy Nathans
    In vitro culture of brain endothelial cells leads to a rapid loss of the blood-brain barrier transcriptional and accessible chromatin landscapes that is resistant to the effects of beta-catenin stabilization.

    Exchange of water for sterol underlies sterol egress from a StARkin domain

    George Khelashvili, Neha Chauhan ... Anant K Menon
    The capture and export of a hydrophobic sterol molecule from the binding pocket of a Lam/GramD1 sterol-binding protein is unexpectedly mediated by water.

    Differential impact of self and environmental antigens on the ontogeny and maintenance of CD4+ T cell memory

    Thea Hogan, Maria Nowicka ... Benedict Seddon
    Comparing mice in clean and dirty environments reveals that environment drives initial establishment and size of T cell memory compartments, but not their maintenance in adults.

    Chromatin-bound CRM1 recruits SET-Nup214 and NPM1c onto HOX clusters causing aberrant HOX expression in leukemia cells

    Masahiro Oka, Sonoko Mura ... Yasuyuki Ohkawa
    A key molecule that connects leukemogenic proteins to aberrant HOX gene regulation turned out to be a nuclear export factor, CRM1.
    1. Genetics and Genomics

    An efficient CRISPR-based strategy to insert small and large fragments of DNA using short homology arms

    Oguz Kanca, Jonathan Zirin ... Hugo J Bellen
    Optimization of homology donor DNA production and integration schemes facilitates homologous recombination in vivo and in cell culture in Drosophila melanogaster..

    Cholesterol accessibility at the ciliary membrane controls hedgehog signaling

    Maia Kinnebrew, Ellen J Iverson ... Rajat Rohatgi
    The patched hedgehog receptor inhibits the transmembrane transducer smoothened by reducing the accessibility of cholesterol locally at the membrane of the primary cilium.

    Cue-inhibited ventrolateral periaqueductal gray neurons signal fear output and threat probability in male rats

    Kristina M Wright, Thomas C Jhou ... Michael A McDannald
    Ventrolateral periaqueductal gray neurons signal fear output through patterned inhibition of neural activity.
