TOP STORY
Clonally Related Visual Cortical Neurons Show Similar Stimulus Feature Selectivity
Using a retroviral vector encoding green fluorescent protein to label radial clones of excitatory neurons, and in vivo two-photon calcium imaging to measure neuronal response properties, researchers found that sister neurons preferred similar orientations whereas nearby non-sister neurons showed no such relationship.

PUBLICATIONS (Ranked by Impact Factor of the Journal)

Sustained Translational Repression by eIF2α-P Mediates Prion Neurodegeneration
Researchers showed that accumulation of prion protein during prion replication causes persistent translational repression of global protein synthesis by the α-subunit of eukaryotic translation initiation factor (eIF2α-P), associated with synaptic failure and neuronal loss in prion-diseased mice. [Nature] Abstract

Thyroid Hormone Signaling Acts as a Neurogenic Switch by Repressing Sox2 in the Adult Neural Stem Cell Niche
Researchers showed that, in the adult subventricular zone, Thyroid Hormone (T3) and its receptor, TRα1, together favor neural stem cell commitment and progression toward a migrating neuroblast phenotype; this transition correlates with T3/TRα1-dependent transcriptional repression of Sox2. [Cell Stem Cell] Abstract

Automated Whole-Cell Patch-Clamp Electrophysiology of Neurons In Vivo
Whole-cell patch-clamp electrophysiology of neurons is a gold-standard technique for high-fidelity analysis of the biophysical mechanisms of neural computation and pathology, but it requires great skill to perform. Researchers developed a robot that automatically performs patch clamping in vivo, algorithmically detecting cells by analyzing the temporal sequence of electrode impedance changes. [Nat Methods]

The p150Glued CAP-Gly Domain Regulates Initiation of Retrograde Transport at Synaptic Termini
Researchers report that the p150Glued CAP-Gly domain regulates dynein-mediated retrograde transport at synaptic termini, and this function of dynactin is disrupted by a mutation that causes motor neuron disease. [Neuron] Abstract

Connexin 43 Controls the Multipolar Phase of Neuronal Migration to the Cerebral Cortex
Researchers demonstrate that connexin 43 regulates the passage of migrating neurons through their multipolar stage via p27 signaling and that interference with this process, by either genetic and/or environmental factors, may cause cortical malformations. [Proc Natl Acad Sci USA] Abstract

Deleterious Effects of Neuronal Accumulation of Glycogen in Flies and Mice
Researchers present evidence that the progressive accumulation of glycogen in mouse and Drosophila neurons leads to neuronal loss, locomotion defects and reduced lifespan. [EMBO Mol Med]

Functional Neuromuscular Junctions Formed by Embryonic Stem Cell-Derived Motor Neurons
Scientists report the development of low-density co-culture conditions that encourage the formation of active neuromuscular synapses between stem cell-derived motor neurons and muscle cells in vitro. [PLoS One]

Pharmacokinetic Study of Neural Stem Cell-Based Cell Carrier for Oncolytic Virotherapy: Targeted Delivery of the Therapeutic Payload in an Orthotopic Brain Tumor Model
Researchers report the characterization of an FDA approved neural stem cell, HB1.F3-CD, as a cell carrier for conditionally replicating adenovirus-S-pk7, a glioma-tropic oncolytic adenovirus. [Cancer Gene Ther] Abstract
