    Fate Mapping of Spp1 Expression Reveals Age-Dependent Plasticity of Disease-Associated Microglia-Like Cells after Brain Injury

    Investigators established a lineage tracing system, leveraging the expression dynamics of secreted phosphoprotein 1 (Spp1) to label and track disease-associated microglia-like microglia during brain injury and recovery.

    Basal Ganglia–Spinal Cord Pathway That Commands Locomotor Gait Asymmetries in Mice

    Performing deep brainstem recordings of Chx10 gigantocellular (Gi) Ca2+ activity in adult mice, researchers showed that striatal projection neurons initiated turning gaits via a dominant crossed pathway to Chx10 Gi neurons on the contralateral side.

    Integrating Spatial and Single-Cell Transcriptomics to Characterize the Molecular and Cellular Architecture of the Ischemic Mouse Brain

    Scientists used spatial transcriptomics to study the ischemic hemisphere in mice after stroke and sequenced the transcriptomes of 19,777 spots, allowing us to both visualize the transcriptional landscape within the tissue and identify gene expression profiles linked to specific histologic entities.

    RNF220-Mediated K63-Linked Polyubiquitination Stabilizes Olig Proteins during Oligodendroglial Development and Myelination

    The authors found that RNF220, a known leukodystrophy-related E3 ubiquitin ligase, was required for oligodendroglial development.

    Cell Type-Specific Expression, Regulation, and Compensation of CDKL5 Activity in Mouse Brain

    Researchers generated conditional Cdkl5 knockout mice in excitatory neurons, inhibitory neurons, and astrocytes. To assess CDKL5 activity, they utilized a phosphospecific antibody for phosphorylated EB2, a well-known substrate of CDKL5.

    A Mammalian-Specific Alex3/Gαq Protein Complex Regulates Mitochondrial Trafficking, Dendritic Complexity, and Neuronal Survival

    By generating a CNS-specific armadillo repeat–containing X-linked protein 3 (Alex3) knockout mouse line, investigators demonstrated that Alex3 was required for the effects of Gαq on mitochondrial trafficking and dendritic growth in neurons.

    Abstract

    The LRRK2 Kinase Substrates RAB8a and RAB10 Contribute Complementary but Distinct Disease-Relevant Phenotypes in Human Neurons

    Researchers used CRISPR-Cas9 genome editing to generate a novel series of isogenic iPSC lines deficient in the two most well-validated LRRK2 substrates, RAB8a and RAB10, from deeply phenotyped healthy control lines.

    Sevoflurane Causes Cognitive Impairment by Inducing Iron Deficiency and Inhibiting the Proliferation of Neural Precursor Cells in Infant Mice

    C57BL/6 mice of postnatal day 14 and neural stem cells NE4C were treated with 2% sevoflurane for six hours. Scientists used the Morris water maze to test the cognitive function of infant mice.

    Mitochondria-Endoplasmic Reticulum Contact Sites (MERCS): A New Axis in Neuronal Degeneration and Regeneration

    Mitochondria-Endoplasmic Reticulum Contact Sites (MERCS) are dynamic structures whose physiological interaction is vital to direct life and death of the cell. Dysregulation of this interplay leads to various neurodegenerative disorders.
