    Kunitz-Type Protease Inhibitor TFPI2 Remodels Stemness and Immunosuppressive Tumor Microenvironment in Glioblastoma

    Scientists identified Kunitz-type protease inhibitor TFPI2 as a critical factor connecting these cell populations and their associated glioblastoma hallmarks of stemness and immunosuppression.

    Human Astrocytes and Microglia Show Augmented Ingestion of Synapses in Alzheimer’s Disease via MFG-E8

    Researchers observed astrocytes and microglia from human brains contained greater amounts of synaptic protein in Alzheimer’s disease compared with non-disease controls, and that proximity to amyloid-β plaques and the APOE4 risk gene exacerbated this effect.

    iPSC Motor Neurons, but Not Other Derived Cell Types, Capture Gene Expression Changes in Postmortem Sporadic ALS Motor Neurons

    Using isogenic pairs of induced pluripotent stem cells (iPSCs) harboring different familial ALS mutations, the authors assessed the capacity of iPSC-derived lower motor neurons, sensory neurons, astrocytes, and superficial cortical neurons to capture disease features.

    BCL2L13 Promotes Mitophagy through DNM1L-Mediated Mitochondrial Fission in Glioblastoma

    Investigators showed that BCL2 like 13 (BCL2L13) expression was significantly upregulated in glioblastoma multiforme (GBM) cell lines and clinical GBM tissue samples.

    Ganglioside GD3 Regulates Neural Stem Cell Quiescence and Controls Postnatal Neurogenesis

    The authors showed that inducible GD3 deletion in postnatal radial glia-like neural stem cell (NSC) promotes NSC activation, resulting in the loss of the long-term maintenance of the adult NSC pools.

    Abstract

    Osimertinib Induces Paraptosis and TRIP13 Confers Resistance in Glioblastoma Cells

    Scientists demonstrated that osimertinib induced paraptosis in glioblastoma cells, as evidenced by the formation of cytoplasmic vacuoles, accumulation of ubiquitinated proteins, and upregulation of endoplasmic reticulum stress markers like CHOP.

    CHCHD2 Mediates Glioblastoma Cell Proliferation, Mitochondrial Metabolism, Hypoxia-Induced Invasion, and Therapeutic Resistance

    Researchers determined whether coiled‑coil‑helix‑coiled‑coil‑helix domain‑containing protein 2 (CHCHD2) played a functional role in U87 glioblastoma cells expressing the constitutively active epidermal growth factor receptor variant III.

    Abstract

    Axo-Glial Interactions between Midbrain Dopamine Neurons and Oligodendrocyte Lineage Cells in the Anterior Corpus Callosum

    Investigators provided evidence implicating midbrain dopamine neurons in the innervation of oligodendrocyte lineage cells in the anterior corpus callosum and nearby white matter tracts of male and female adult mice.

    FGF21 Prevents Neuronal Cell Ferroptosis after Spinal Cord Injury by Activating the FGFR1/β-Klotho Pathway

    The authors investigated the potential of recombinant human FGF21 in inhibiting ferroptosis of nerve cells and improving limb function after spinal cord injury, along with its underlying mechanisms.

    Targeting NLRP3 Inflammasome for Neurodegenerative Disorders

    Scientists review the mechanisms of NACHT, LRR, and PYD domains-containing protein 3 (NLRP3) expression and activation and discussed the role of active NLRP3 inflammasome in the pathogenesis of neurodegenerative diseases, particularly focusing on Alzheimer’s disease.

    Abstract

    Metabolic Partitioning in the Brain and Its Hijacking by Glioblastoma

    Investigators provide an overview of the intercellular division of metabolic labor that occurs in both the normal brain and the glioblastoma (GBM) tumor microenvironment and then discuss the implications of these interactions for GBM therapy.
