TOP STORY
Direct Reprogramming of Mouse and Human Fibroblasts into Multipotent Neural Stem Cells with a Single Factor
Researchers report the generation of induced neural stem cells from mouse and human fibroblasts by direct reprogramming with a single factor, Sox2. [Cell Stem Cell] Abstract | Press Release

Culture primary neurons independent of substrate with NeuroCult™ SM2

Fruitless Recruits Two Antagonistic Chromatin Factors to Establish Single-Neuron Sexual Dimorphism
Scientists showed that Fruitless forms a complex with the transcriptional cofactor Bonus, which, in turn, recruits either of two chromatin regulators, Histone deacetylase 1, which masculinizes individual sexually dimorphic neurons, or Heterochromatin protein 1a, which demasculinizes them. [Cell] Abstract

dSarm/Sarm1 Is Required for Activation of an Injury-Induced Axon Death Pathway
Researchers showed that loss of the Drosophila Toll receptor adaptor dSarm (sterile α/Armadillo/Toll-Interleukin receptor homology domain protein) cell-autonomously suppresses Wallerian degeneration for weeks after axotomy. [Science] Abstract | Press Release

Silencing MicroRNA-134 Produces Neuroprotective and Prolonged Seizure-Suppressive Effects
Silencing of microRNA-134 expression in vivo using antagomirs reduced hippocampal CA3 pyramidal neuron dendrite spine density by 21% and rendered mice refractory to seizures and hippocampal injury caused by status epilepticus. [Nat Med] Abstract

Autism Spectrum Disorder Susceptibility Gene Thousand-and-One-Amino Acid 2 Kinase (TAOK2) Affects Basal Dendrite Formation in the Neocortex
The authors describe a new pathway that specifically affects the formation of basal dendrites and axonal projections in cortical pyramidal neurons. [Nat Neurosci] Abstract

Whole-Brain Mapping of Direct Inputs to Midbrain Dopamine Neurons
The authors demonstrated that neurons in the striatum that project directly to dopamine neurons form patches in both the dorsal and ventral striatum, whereas those projecting to GABAergic neurons are distributed in the matrix compartment. [Neuron] Abstract | Press Release

Maternal Loss of Ube3a Produces an Excitatory/Inhibitory Imbalance through Neuron Type-Specific Synaptic Defects
Researchers found that there are neuron type-specific synaptic deficits in Angelman syndrome model mice, which carry a maternal Ube3a null mutation despite the presence of Ube3a in all neurons. These deficits result in excitatory/inhibitory imbalance at cellular and circuit levels and may contribute to seizure susceptibility in Angelman syndrome. [Neuron] Abstract | Press Release

Pervasive Synaptic Branch Removal in the Mammalian Neuromuscular System at Birth
Using light and serial electron microscopy, researchers showed profound refinements in motor axonal branching and synaptic connectivity before and after birth. Embryonic axons become maximally connected just before birth when they innervate ten-fold more muscle fibers than in maturity. [Neuron]

Analysis of Neural Subtypes Reveals Selective Mitochondrial Dysfunction in Dopaminergic Neurons from Parkin Mutants
Whether PINK1 or Parkin influence mitochondrial quality control under normal physiological conditions in dopaminergic neurons, a principal cell type that degenerates in Parkinson disease, remains unclear. To address this matter, researchers developed a method to purify and characterize neural subtypes of interest from the adult Drosophila brain. [Proc Natl Acad Sci USA] Abstract
