    An Epigenetic Barrier Sets the Timing of Human Neuronal Maturation

    Scientists developed a human pluripotent stem cell-based approach to synchronize the birth of cortical neurons in vitro which helped to define an atlas of morphological, functional, and molecular maturation.

    Microglia Maintain Structural Integrity during Fetal Brain Morphogenesis

    Investigators uncovered a role for microglia in the maintenance of structural integrity at two fetal cortical boundaries.

    Clearance of β-Amyloid and Synapses by the Optogenetic Depolarization of Microglia Is Complement Selective

    Researchers employed optogenetic methods to stimulate microglia in vitro and in vivo. Membrane depolarization rapidly changed microglia morphology and led to enhanced phagocytosis.

    Phosphorylation of Human Glioma-Associated Oncogene 1 on Ser937 Regulates Sonic Hedgehog Signaling in Medulloblastoma

    The authors showed that sonic hedgehog (SHH) inactivated p38α in a smoothened-dependent manner, conversely, p38α directly phosphorylated GLI1 on Ser937/Ser941 to induce GLI1’s proteasomal degradation and negated the transcription of SHH signaling.

    TwinF Interface Inhibitor FP802 Stops Loss of Motor Neurons and Mitigates Disease Progression in a Mouse Model of ALS

    Investigators took advantage of TwinF interface inhibition that allowed selective elimination of extrasynaptic NMDA receptor-mediated toxicity via disruption of the NMDAR/TRPM4 death signaling complex while sparing the vital physiological functions of synaptic NMDARs.

    Astrocyte-Induced mGluR1 Activates Human Lung Cancer Brain Metastasis via Glutamate-Dependent Stabilization of EGFR

    Scientists developed a simple and stable culture method of mouse glial cells, termed mixed-glial culture on/in soft substrate, which served well as a platform to study cancer-glia interactions.

    AbstractGraphical Abstract

    The DDHD2-STXBP1 Interaction Mediates Long-Term Memory via Generation of Saturated Free Fatty Acids

    Investigators showed that genetic ablation of the phospholipase A1 isoform DDHD2 in mice dramatically reduced saturated free fatty acid responses to memory acquisition across the brain.

    Th1 Cells Contribute to Retinal Ganglion Cell Loss in Glaucoma in a VCAM-1-Dependent Manner

    Scientists unraveled the multifaceted nature of glaucoma by investigating the interaction between T cells and retinas by utilizing clinical samples, murine glaucoma models, and T cell transfer models.

    Similar Brain Proteomic Signatures in Alzheimer’s Disease and Epilepsy

    The authors identified protein differences associated with epilepsy and Alzheimer’s disease using published proteomics datasets.
