    Pharmacological Perturbation of CXCL1 Signaling Alleviates Neuropathogenesis in a Model of HEVA71 Infection

    Investigators showed that human enterovirus A71 (HEVA71)-infected astrocytes released CXCL1 which supported viral replication in neurons by activating the CXCR2 receptor-associated ERK1/2 signaling pathway.

    Activation-Induced Chromatin Reorganization in Neurons Depends on HDAC1 Activity

    Researchers showed that stimulation of neurons caused condensation of large chromatin domains. This phenomenon could be observed in vitro in cultured rat hippocampal neurons as well as in vivo in the amygdala and hippocampal neurons.

    Metabolic Control of Adult Neural Stem Cell Self-Renewal by the Mitochondrial Protease YME1L

    Scientists disclosed an important role for YME1L in coordinating the switch between metabolic states of neural stem and progenitor cells (NSPCs) and suggested that NSPC fate was regulated by compartmentalized changes in protein network dynamics.

    LINC01296 Promotes Neuroblastoma Tumorigenesis via the NCL-SOX11 Regulatory Complex

    The authors identified that silencing LINC01296 repressed neuroblastoma cell proliferation and migration, and promoted apoptosis. LINC01296 knockdown inhibited tumor growth in vivo.

    High Content Screening and Proteomic Analysis Identify a Kinase Inhibitor That Rescues Pathological Phenotypes in a Patient-Derived Model of Parkinson’s Disease

    Investigators applied high content imaging on induced pluripotent stem cell-derived neurons from patients with familial Parkinson’s disease bearing the G209A α-synuclein mutation and launched a screening campaign on a small kinase inhibitor library.

    C1GALT1 Expression Predicts a Favorable Prognosis and Suppresses Malignant Phenotypes via TrkA Signaling in Neuroblastoma

    The authors provided the first evidence for the existence of GalNAc-type O-glycans on TrkA and altered O-glycan structures by core 1 β1,3-galactosyltransferase (C1GALT1) could regulate TrkA signaling in neuroblastoma cells.

    Dual-sgRNA CRISPR/Cas9 Knockout of PD-L1 in Human U87 Glioblastoma Tumor Cells Inhibits Proliferation, Invasion, and Tumor-Associated Macrophage Polarization

    Scientists showed that utilizing dual-single guide RNAs (sgRNAs) and a homology-directed repair template with the CRISPR/Cas9 gene-editing system could be a promising avenue for the treatment of glioblastoma multiforme.

    Humanin Inhibits Necrotic Cell Death in Neurons

    Investigators found that AGA(C8R)-HNG17 conferred protection against necrosis in neuronal cell lines PC-12 and NSC-34, where necrosis was induced in a glucose-free medium by either chemohypoxia or by a shift from apoptosis to necrosis.
