    TOP STORY

    Promoting Regeneration While Blocking Cell Death Preserves Motor Neuron Function in a Model of ALS

    Researchers studied whether combining dual leucine zipper kinase deletion with a way to promote axon regeneration would result in greater motor neuron protection, demonstrating the power of combinatorial therapy to treat neurodegenerative disease.

    High-Throughput Morphometric and Transcriptomic Profiling Uncovers Composition of Naïve and Sensory-Deprived Cortical Cholinergic VIP/CHAT Neurons

    Scientists studied the morphological and transcriptional diversity of cortical cholinergic VIP/ChAT interneurons, a sparse population with a largely unknown function.

    Depressive Patient-Derived GABA Interneurons Reveal Abnormal Neural Activity Associated with HTR2C

    Investigators generated induced pluripotent stem cells (iPSC) from five patients with major depressive disorders with suicidal behavior and differentiated the iPSCs into GABAergic interneurons and ventral forebrain organoids.

    DHODH Inhibition Impedes Glioma Stem Cell Proliferation, Induces DNA Damage, and Prolongs Survival in Orthotopic Glioblastoma Xenografts

    Researchers demonstrated that glioma stem cells (GSCs) lacking epidermal growth factor receptor (EGFR) amplification are exquisitely sensitive to de novo pyrimidine synthesis perturbations, while GSCs that amplify EGFR were utterly resistant.

    Abstract

    Peptains Block Retinal Ganglion Cell Death in Animal Models of Ocular Hypertension: Implications for Neuroprotection in Glaucoma

    Scientists investigated the effects of the antiapoptotic peptides peptain-1 and peptain-3a on retinal ganglion cell (RGC) death in vitro in rat primary RGCs and in mouse models of ocular hypertension.

    Conditioned Medium from BV2 Microglial Cells Having Polyleucine Specifically Alters Startle Response in Mice

    Investigators studied whether only microglia containing a specific repeat-associated non-AUG (RAN) product, but not other RAN products, was harmful in vitro and in vivo. They demonstrated that polyL-incorporating microglia specifically led to altered startle response in mice.

    Electrical Stimulation Enhances the Neuronal Differentiation of Neural Stem Cells in Three-Dimensional Conductive Scaffolds through the Voltage-Gated Calcium Ion Channel

    Scientists showed that hippocampal astrocyte calcium activity reflected mouse affective state during a virtual elevated plus maze test using two-photon calcium imaging in vivo.

    Abstract

    Ginsenoside Rg1 in Neurological Diseases: From Bench to Bedside

    Investigators summarize the research progress on the action mechanisms of Rg1 ameliorating depression-like behaviors, including inhibition of hyperfunction of the hypothalamic-pituitary-adrenal axis, regulation of synaptic plasticity, and gut flora.
