    Lamellar projections in the endolymphatic sac act as a relief valve to regulate inner ear pressure

    Ian A Swinburne, Kishore R Mosaliganti ... Sean G Megason
    The pressure of fluid in the inner ear is controlled by opening of cellular valves in the endolymphatic sac to allow for regulated transepithelial fluid flow.

    Allosteric inhibition of a stem cell RNA-binding protein by an intermediary metabolite

    Carina C Clingman, Laura M Deveau ... Sean P Ryder
    The RNA-binding protein MSI1, which is required for stem cell and cancer cell proliferation in the brain and epithelial tissues, also directly senses the concentration of long non-esterified omega-9 fatty acids.

    Size control of the inner ear via hydraulic feedback

    Kishore R Mosaliganti, Ian A Swinburne ... Sean G Megason
    Size regulation of the otic vesicle, the progenitor of the inner ear, is mediated by mechanical feedback involving fluid influx, hydraulic pressure, and tissue mechanics.

    Replacing the PDZ-interacting C-termini of DSCAM and DSCAML1 with epitope tags causes different phenotypic severity in different cell populations

    Andrew M Garrett, Abigail LD Tadenev ... Robert W Burgess
    Mammalian Dscams require different intracellular interactions in different cell types during neural circuit formation to promote self-avoidance.

    Inhibitory CCK+ basket synapse defects in mouse models of dystroglycanopathy

    Jennifer N Jahncke, Daniel S Miller ... Kevin M Wright
    Loss of functional dystroglycan disrupts the formation and function of CCK+/CB1R+ inhibitory synapses in hippocampal CA1, resulting in reduced seizure thresholds in mouse models of dystroglycanopathy.

    Loss of aquaporin-4 results in glymphatic system dysfunction via brain-wide interstitial fluid stagnation

    Ryszard Stefan Gomolka, Lauren M Hablitz ... Yuki Mori
    Mice with aquaporin-4 channel deletion exhibit larger interstitial spaces, brain volume and water content, alongside reduced CSF space volume, which may increased resistance towards brain fluid efflux and suppress glymphatic flow.

    Giant ankyrin-B mediates transduction of axon guidance and collateral branch pruning factor sema 3A

    Blake A Creighton, Simone Afriyie ... Damaris N Lorenzo
    Giant ankyrin-B enables the transduction of Sema 3A repelling cues and is important for normal axonal connectivity.

    STAG2 promotes the myelination transcriptional program in oligodendrocytes

    Ningyan Cheng, Guanchen Li ... Hongtao Yu
    Brain-specific inactivation of cohesin-STAG2 in the mouse causes myelination defects, thus implicating hypomyelination as a contributing factor to cohesinopathy and establishing oligodendrocytes as a cell system to probe the physiological function of cohesin-mediated genome folding.
