    iPS-Cell-Derived Microglia Promote Brain Organoid Maturation via Cholesterol Transfer

    Scientists generated microglia-sufficient brain organoids by coculturing brain organoids with primitive-like macrophages generated from the same human induced pluripotent stem cells.

    CHIT1-Positive Microglia Drive Motor Neuron Aging in the Primate Spinal Cord

    The authors identified a previously unreported neurotoxic microglial state demarcated by elevated expression of CHIT1 specific to the aged spinal cords in non-human primate and human biopsies.

    Abstract

    Fe65-Engineered Neuronal Exosomes Encapsulating Corynoxine-B Ameliorate Cognition and Pathology of Alzheimer’s Disease

    The engineering of hippocampus neuron cell-derived exosomes to overexpress Fe65, enabled the development of a novel exosome-based targeted drug delivery system, which carried Corynoxine-B to the amyloid-β precursor protein overexpressed-neuron cells in the brain of Alzheimer’s disease mice.

    Multivalent Tau/PSD-95 Interactions Arrest In Vitro Condensates and Clusters Mimicking the Postsynaptic Density

    Investigators showed that Tau arrested liquid-like droplets formed by the four postsynaptic density proteins PSD-95, GKAP, Shank, Homer in solution, as well as N-methyl-D-aspartate-receptor-associated protein clusters on synthetic membranes.

    The α-Synuclein PET Tracer [18F] ACI-12589 Distinguishes Multiple System Atrophy from Other Neurodegenerative Diseases

    Using autoradiography and radiobinding techniques, researchers showed that the positron emission tomography (PET) ligand, ACI-12589, displayed good in vitro affinity and specificity for pathological α-synuclein in tissues from patients with different α-synuclein-related disorders.

    Human Cerebrospinal Fluid Affects Chemoradiotherapy Sensitivities in Tumor Cells from Patients with Glioblastoma

    Investigators examined the effect of human cerebrospinal fluid (CSF) on glioblastoma (GBM) tumors from 25 patients. They found that CSF induces tumor cell plasticity and resistance to standard GBM treatments, temozolomide and irradiation.

    The E3 Ligase TRIM26 Suppresses Ferroptosis through Catalyzing K63-Linked Ubiquitination of GPX4 in Glioma

    Investigators identified the tripartite motif-containing protein, TRIM26 as an E3 ubiquitin ligase of GPX4. TRIM26 directly interacted with GPX4 through its Ring domain and catalyzed the ubiquitination of GPX4 at K107 and K117.

    Neuron-Secreted NLGN3 Ameliorates Ischemic Brain Injury via Activating Gαi1/3-Akt Signaling

    Scientists tested the potential activity and the underlying mechanisms of neuroligin-3 (NLGN3) against ischemia-reperfusion-induced neuronal cell injury.

    Dynamic Reversibility of α-Synuclein Serine-129 Phosphorylation Is Impaired in Synucleinopathy Models

    The authors showed that Parkinson’s disease-linked missense mutations in SNCA impacted activity-dependent pS129. Under basal conditions, cytosol-enriched A30P, H50Q, and G51D mutant forms of α-synuclein exhibited reduced pS129 levels in rat primary cortical neurons.

    Chronic Administration of XBD173 Ameliorates Cognitive Deficits and Neuropathology via 18 kDa Translocator Protein (TSPO) in a Mouse Model of Alzheimer’s Disease

    To study whether the TSPO ligand XBD173 may exert early neuroprotective effects in Alzheimer’s disease (AD) pathology, researchers investigated the impact of XBD173 on amyloid toxicity and neuroplasticity in mouse models of AD.
