    TOP STORY

    γ-Protocadherins Control Synapse Formation and Peripheral Branching of Touch Sensory Neurons

    The clustered protocadherin gamma 3 isoform mediated homophilic interactions between sensory axons and spinal cord neurons to promote synapse formation in vivo and was sufficient to induce postsynaptic specializations in vitro.

    Buffering of Transcription Rate by mRNA Half-Life Is a Conserved Feature of Rett Syndrome Models

    Scientists measured transcription rate and mRNA half-life changes in Rett syndrome patient neurons using RATEseq, and re-interpreted nuclear and whole-cell RNAseq from methyl CpG-binding protein 2 (Mecp2) mice.

    Glucocerebrosidase Is Imported into Mitochondria and Preserves Complex I Integrity and Energy Metabolism

    Researchers employed global proteomic and single-cell genomic approaches in stable cell lines as well as induced pluripotent stem cell-derived neurons and midbrain organoids to dissect the mechanisms underlying β-glucocerebrosidase-related neurodegeneration.

    3D Reconstruction of the Cerebellar Germinal Layer Reveals Tunneling Connections between Developing Granule Cells

    The authors used a connectomic approach using a high-resolution, serial-sectioning scanning electron microscopy volume to investigate the laminar cytoarchitecture of the transient external granular layer of the developing cerebellum, where granule cells coordinate a series of mitotic and migratory events.

    Connexin 43-Mediated Neurovascular Interactions Regulate Neurogenesis in the Adult Brain Subventricular Zone

    Investigators found that connexin-43 (Cx43) was highly expressed by subventricular zone neural stem cells (NSC) and endothelial cells (EC), and its deletion in either led to increased NSC proliferation and neuroblast generation, suggesting that Cx43-mediated NSC-EC interactions maintained NSC quiescence.

    Decoding the Molecular Crosstalk between Grafted Stem Cells and the Stroke-Injured Brain

    Using translating ribosome affinity purification with sequencing tools, researchers simultaneously decoded the transcriptomes of graft and host for human neural stem cells transplanted into the stroke-injured rat brain.

    Dedifferentiation-Derived Neural Stem Cells Exhibit Perturbed Temporal Progression

    Scientists showed that ectopic neural stem cells induced via basic helix–loop–helix transcription factor Deadpan expression failed to undergo appropriate temporal progression by constantly expressing mid-temporal transcription factor, Sloppy-paired 1/2.

    IGFBP3 Induced by the TGF-β/EGFRvIII Transactivation Contributes to the Malignant Phenotype of Glioblastoma

    Insulin-like growth factor binding protein-3, IGFBP3, knockdown inhibited the activation of transforming growth factor-β (TGF-β) and epidermal growth factor receptor variant III (EGFRvIII) signals and the malignant behaviors triggered by them in vitro and in vivo.

    A Hydrogel Model of the Human Blood-Brain Barrier Using Differentiated Stem Cells

    An in vitro model of the human blood-brain barrier was developed, based on a collagen hydrogel containing astrocytes, overlaid with a monolayer of endothelium, differentiated from human induced pluripotent stem cells.

    The Synaptic Hypothesis of Schizophrenia Version III: A Master Mechanism

    Scientists review normal synaptic development and evidence from structural and functional imaging and post-mortem studies that this is abnormal in people at risk and with schizophrenia. They then consider the mechanism that could underlie synaptic changes and update the hypothesis.
