TOP STORY
Tiny Spheres of Human Cells Mimic the Brain
Researchers have figured out how to create spheres of neuronal cells resembling the cerebral cortex, making functional human brain tissue available for the first time to study neuropsychiatric diseases such as autism and schizophrenia. [Press release from Stanford Medicine discussing online prepublication in Nature Methods] Press Release | Abstract
Neural Supplements For High-Quality Neural Cell Cultures
 
PUBLICATIONS (Ranked by impact factor of the journal)
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. [Stem Cells Rep] Full Article | Graphical Abstract

REVIEWS
NG2-Glia and Their Functions in the Central Nervous System
The authors discuss some of the most current and highly debated issues regarding NG2-glia. They highlight the importance of NG2-glia not only in the healthy, but also in the diseased brain. [Glia] Abstract

The Role of Gangliosides in Neurodevelopment
Gangliosides are important components of neuronal cell membranes and it is widely accepted that they play a critical role in neuronal and brain development. They are functionally involved in neurotransmission and are thought to support the formation and stabilization of functional synapses and neural circuits required as the structural basis of memory and learning.
