    Linoleic Acid Improves PIEZO2 Dysfunction in a Mouse Model of Angelman Syndrome

    Scientists reported that PIEZO2 activity was reduced in female human induced pluripotent stem cell-derived sensory neurons with UBE3A knock-down, and de-identified stem cell-derived neurons from individuals with Angelman syndrome.

    Zika Virus RNA Structure Controls Its Unique Neurotropism by Bipartite Binding to Musashi-1

    Researchers identified the AUAG motif and the AGAA tetraloop in the Xrn1-resistant RNA 2 as the canonical and non-canonical MSI1 binding sites, respectively, and both are crucial for Zika virus neurotropism.

    Human Brain Organoid Model of Maternal Immune Activation Identifies Radial Glia Cells as Selectively Vulnerable

    Investigators established a human 3D in vitro model of maternal immune activation by treating induced pluripotent stem cell-derived dorsal forebrain organoids with a constitutively active form of IL-6, Hyper-IL-6.

    TRIM56 Acts through the IQGAP1-CDC42 Signaling Axis to Promote Glioma Cell Migration and Invasion

    The authors provided insights into the mechanisms through which tripartite motif containing 56 (TRIM56) promoted glioma motility, by regulating IQGAP1 ubiquitination to promote CDC42 activation, which may be clinically targeted for the treatment of glioma.

    Dying Transplanted Neural Stem Cells Mediate Survival Bystander Effects in the Injured Brain

    Scientists provided evidence that caspase-dependent apoptotic cell death of neural stem and progenitor cells was required for sending survival signals to the injured brain.

    Non-Muscle Myosins Control Radial Glial Basal Endfeet to Mediate Interneuron Organization

    Investigators employed in vivo proximity labeling, in the mouse, using unfused BirA to generate the first subcellular proteome of radial glial cells and uncovered new principles governing local control of cortical development.

    E3 Ligase MAEA-Mediated Ubiquitination and Degradation of PHD3 Promotes Glioblastoma Progression

    Through the tandem mass tag-based quantitative proteomic analysis of clinical primary and recurrent glioma samples, scientists identified that aberrant E3 ligase MAEA was expressed in recurrent samples.

    Abstract

    Transplantation of Glutamatergic Neuronal Precursor Cells in the Paraventricular Thalamus and Claustrum Facilitates Awakening with Recovery of Consciousness

    Investigators found that the deterioration in the level and content of consciousness after traumatic brain injury was associated with a large reduction in glutamatergic neurons within the paraventricular thalamus and claustrum.

    Direct Targeting of DOCK4 by miRNA-181d in Oxygen-Glucose Deprivation/Reoxygenation-Mediated Neuronal Injury

    To replicate in vivo and in vitro cerebral ischemia/reperfusion injury, a transient middle cerebral artery occlusion model in rats and an oxygen-glucose deficiency/reoxygenation model in neuro 2A cells were developed.
