| PUBLICATIONS (Ranked by impact factor of the journal) | p27Kip1 Is a Microtubule-Associated Protein that Promotes Microtubule Polymerization during Neuron Migration The migration of cortical interneurons is characterized by extensive morphological changes that result from successive cycles of nucleokinesis and neurite branching. Their molecular bases remain elusive, therefore researchers examined how p27Kip1 controls cell-cycle-unrelated signaling pathways to regulate these morphological remodelings. [Dev Cell] Abstract NKCC1 Knockdown Decreases Neuron Production through GABAA-Regulated Neural Progenitor Proliferation and Delays Dendrite Development To examine GABAA function in vivo, the authors electroporated plasmids encoding short-hairpin RNA against the Na-K-2Cl cotransporter (NKCC1) in neural progenitor cells of the neonatal subventricular zone in mice to reduce GABAA-induced depolarization. [J Neurosci] Abstract The Nuclear Receptor TLX Is Required for Gliomagenesis within the Adult Neurogenic Niche Investigators examined the genetic interactions between TLX and several tumor suppressors, as well as the role of TLX-dependent neural stem cells (NSCs) during gliomagenesis, using mouse models. They showed that TLX is essential for the proliferation of adult NSCs with single deletion of p21, p53, Pten, or combined deletion of Pten and p53. [Mol Cell Biol] Abstract Ciliary Neurotrophic Factor Activates NF-κB to Enhance Mitochondrial Bioenergetics and Prevent Neuropathy in Sensory Neurons of Streptozotocin-Induced Diabetic Rodents Investigators hypothesized that ciliary neurotrophic factor (CNTF) protects sensory neuron function during diabetes through normalization of impaired mitochondrial bioenergetics. They also investigated whether the NF-κB signal transduction pathway was mobilized by CNTF. [Neuropharmacology] Abstract γ-Secretase Inhibitors Prevent Overgrowth of Transplanted Neural Progenitors Derived from Human-Induced Pluripotent Stem Cells Researchers used γ-secretase inhibitors to dampen Notch signaling in human-induced pluripotent stem cell-derived neural progenitors before transplantation and examined the effects on the growth of proliferative grafts. [Stem Cells Dev] Abstract Mitogen- and Stress-Activated Kinases Regulate Progenitor Cell Proliferation and Neuron Development in the Adult Dentate Gyrus The authors examined the role of the MAPK-regulated kinases, mitogen and stress activated kinase 1 and 2, as regulators of dentate gyrus subgranular zone progenitor cell proliferation and neurogenesis. [J Neurochem] Abstract Limited Phenotypic Effects of Selectively Augmenting the SMN Protein in the Neurons of a Mouse Model of Severe Spinal Muscular Atrophy To explore the tissue-specific requirements for survival motor neuron (SMN) and the salutary effects of restoring normal levels of the protein to neuronal tissue of affected individuals, researchers selectively expressed the protein in neurons of mice that model severe SMA. [PLoS One] Full Article Neuroprotective Actions of Glucagon-Like Peptide-1 in Differentiated Human Neuroprogenitor Cells Glucagon-like peptide-1 (GLP-1)-based therapies are currently available for the treatment of type 2 diabetes, based on their actions on pancreatic β cells. GLP-1 is also known to exert neuroprotective actions. To determine its mechanism of action, scientists developed a neuron-rich cell culture system by differentiating human neuroprogenitor cells in the presence of a combination of neurotrophins and retinoic acid. [J Neurochem] Abstract Model for Studying Clostridium botulinum Neurotoxin Using Differentiated Motor Neuron-Like NG108-15 Cells The authors demonstrated that the mouse neuroblastoma/rat glioma hybrid cell line NG108-15 is capable of more sensitively detecting BoNT/A1 than any cell line previously described. This cell line has previously been described to have motor neuron like characteristics, therefore making it a good model to study BoNTs. [Biochem Biophys Res Commun] Abstract

| REVIEWS | Structural Tuning and Plasticity of the Axon Initial Segment in Auditory Neurons The axon initial segment (AIS) of nucleus magnocellularis neurons elongate to increase their excitability when synaptic inputs are removed by cochlea ablation, suggesting their contribution to the homeostatic control of neural activity. These structural tunings and plasticities of the AIS are thus indispensable for the function of the auditory circuits in both normal and pathological conditions. [J Physiol] Abstract |
