    Alternative Splicing of Latrophilin-3 Controls Synapse Formation

    Researchers showed in mice that latrophilin-3 organized synapses through a convergent dual-pathway mechanism: activation of Gαs signaling and recruitment of phase-separated postsynaptic protein scaffolds.

    Targeted mRNA Nanoparticles Ameliorate Blood–Brain Barrier Disruption Postischemic Stroke by Modulating Microglia Polarization

    In a transient middle cerebral artery occlusion (MCAO) mouse model of an ischemic stroke, the authors demonstrated that intravenously injected mIL-10@MLNPs induce IL-10 production and enhance the M2 polarization of microglia.

    Triggering Receptor Expressed on Myeloid Cells 2 (TREM2) Regulates Phagocytosis in Glioblastoma

    Using two distinct murine glioma models, researchers examined the role of Trem2 on tumor progression and immune modulation of myeloid cells.

    Abstract

    Neural Population Dynamics Reveals Disruption of Spinal Circuits’ Responses to Proprioceptive Input during Electrical Stimulation of Sensory Afferents

    Investigators studied the effects of electrical stimulation of cutaneous afferents on unrelated processing of proprioceptive inputs. They recorded intraspinal neural activity in four monkeys while generating proprioceptive inputs from the radial nerve.

    Gatad2b, Associated with the Neurodevelopmental Syndrome GAND, Plays a Critical Role in Neurodevelopment and Cortical Patterning

    To study mechanisms of pathogenesis for GATA zinc finger domain containing 2B (GATAD2B), scientists characterized a mouse model harboring an inactivating mutation in Gatad2b.

    Hindbrain Boundaries as Niches of Neural Progenitor/Stem Cells Regulated by the Extracellular Matrix Proteoglycan Chondroitin Sulphate

    To address whether chondroitin sulphate proteoglycan was significant for hindbrain development, its expression was manipulated in vivo and in vitro.

    Abstract

    The Role of PLAG1 in Mouse Brain Development and Neurogenesis

    Investigators reported the spatial distribution and functional implications of pleomorphic adenoma gene 1 (PLAG1) expression in the adult mouse brain.

    DNA Methylation-Mediated Repression of microRNA-410 Promotes the Growth of Human Glioma Cells and Triggers Cell Apoptosis through Its Interaction with STAT3

    Scientists confirmed the observed underexpression of miRNA-410 in glioma tissues and several glioma cells by Quantitative RT-PCR. Their findings suggested that epigenetic alterations occurring at the promoter region of miR-410 may be responsible for the reduced expression of miR-410 in glioma.

    Analysis of Brain Tumor Blood Vessels Yields a Candidate Therapy—And a Platform to Find More

    A Ludwig Cancer Research study has generated a granular portrait of how the cellular and molecular components of the blood vessels that feed brain metastases of melanoma and lung and breast cancers differ from those of healthy brain tissue.
