Single-Cell Transcriptome Analyses Reveal Signals to Activate Dormant Neural Stem Cells Administration of vascular endothelial growth factor activated CD133+ ependymal neural stem cells, lining not only the lateral but also the fourth ventricles and, together with basic fibroblast growth factor, elicited subsequent neural lineage differentiation and migration. [Cell] Abstract | Graphical Abstract Single Transcription Factor Conversion of Human Blood Fate to NPCs with CNS and PNS Developmental Capacity Scientists generated induced neural progenitor cells (NPCs) from neonatal and adult peripheral blood using single-factor OCT4 reprogramming. Unlike fibroblasts that share molecular hallmarks of neural crest, OCT4 reprogramming of blood was facilitated by SMAD+GSK-3 inhibition to overcome restrictions on neural fate conversion. [Cell Rep] Full Article | Graphical Abstract | Press Release Morphine Promotes Astrocyte-Preferential Differentiation of Mouse Hippocampal Progenitor Cells via PKCε-Dependent ERK Activation and TRBP Phosphorylation By using neural progenitor cell (NPCs) cultured from PKCε or β-arrestin2 knockout mice and the MEK inhibitor U0126, scientists demonstrated that regulation of NPC differentiation via the miR-181a/Prox1/Notch1 pathway exhibits ligand-dependent selectivity. [Stem Cells] Abstract A Herbal Medicine for Alzheimer’s Disease and Its Active Constituents Promote Neural Progenitor Proliferation Researchers found that the extract of Rhizoma Acori tatarinowii (AT) and its active constituents, asarones, promote neural progenitor cell (NPC) proliferation. Oral administration of AT enhanced NPC proliferation and neurogenesis in the hippocampi of adult and aged mice as well as that of transgenic Alzheimer’s disease model mice. [Aging Cell] Full Article DPP-4 Inhibitor Linagliptin Attenuates Aβ-Induced Cytotoxicity through Activation of AMPK in Neuronal Cells Scientists evaluated the mechanisms by which linagliptin protects against Aβ-induced impaired insulin signaling and cytotoxicity in cultured SK-N-MC human neuronal cells. [CNS Neurosci Ther] Full Article The ROR2 Tyrosine Kinase Receptor Regulates Dendritic Spine Morphogenesis in Hippocampal Neurons The authors report that ROR2 is distributed in the dendrites of hippocampal neurons in close proximity to synaptic contacts and it is contained in dendritic spine protrusions. They demonstrated that ROR2 is necessary to maintain dendritic spine number and morphological distribution in cultured hippocampal neurons. [Mol Cell Neurosci] Abstract Microglia Activation and Interaction with Neuronal Cells in a Biochemical Model of Mevalonate Kinase Deficiency Investigators evaluated the effect of the mevalonate blocking on glial cells and the following effects on neuronal cells when the two populations were cultured together. [Apoptosis] Abstract Foxp1 Regulates Cortical Radial Migration and Neuronal Morphogenesis in Developing Cerebral Cortex The authors report that suppression of Foxp1 expression in mouse cerebral cortex led to a neuronal migration defect, which was rescued by overexpression of Foxp1. [PLoS One] Full Article Ammonia-Induced Oxidative Damage in Neurons Is Prevented by Resveratrol and Lipoic Acid with Participation of Heme Oxygenase 1 Investigators demonstrated that ammonia can induce direct effects on neuronal cells. The cell viability was decreased by ammonia in SH-SY5Y cells and cerebellar granule neurons. [Neurotoxicology] Abstract Expression of REST4 in Human Gliomas In Vivo and Influence of Pioglitazone on REST In Vitro Scientists showed that pioglitazone can inhibit proliferation and induce apoptosis of glioma cell in vitro, which may be mediated by down-regulating repressor element-1 silencing transcription factor (REST) mRNA level but not by inducing alternative splicing of REST pre-mRNA. [Biochem Biophys Res Commun] Abstract Monosynaptic Tracing using Modified Rabies Virus Reveals Early and Extensive Circuit Integration of Human Embryonic Stem Cell-Derived Neurons Researchers used modified rabies virus to trace afferent and efferent connectivity of transplanted human embryonic stem cell-derived neurons in a rat model of Parkinson’s disease and report that grafted human neurons integrate into the host neural circuitry in an unexpectedly rapid and extensive manner.
