TOP STORY
In Directing Stem Cells, Study Shows Context Matters
Investigators show that a soft, brain tissue-like surface, independent of any soluble factors, was catalyst enough to direct cells to become neurons, the large elaborate cells that make up the central nervous system. Stiffer surfaces favored the stem cell state.

PUBLICATIONS (Ranked by impact factor of the journal)
Local CRH Signaling Promotes Synaptogenesis and Circuit Integration of Adult-Born Neurons
With the goal of identifying signaling mechanisms that underlie neuronal circuit integration in the adult brain, researchers have virally traced local corticotropin-releasing hormone (CRH)-expressing inhibitory interneurons with extensive presynaptic inputs onto new neurons that are continuously integrated into the adult rodent olfactory bulb. [Dev Cell] Abstract | Graphical Abstract

AMPK Modulates Tissue and Organismal Aging in a Non-Cell-Autonomous Manner
The authors show that upregulation of AMPK in the adult Drosophila nervous system induces autophagy both in the brain and also in the intestinal epithelium. Neuronal upregulation of the autophagy-specific protein kinase Atg1 is both necessary and sufficient to induce these intertissue effects during aging and to prolong the lifespan.

CHD7 Maintains Neural Stem Cell Quiescence and Prevents Premature Stem Cell Depletion in the Adult Hippocampus
Using an inducible knockout mouse model, scientists show that the chromatin remodeling factor chromodomain-helicase-DNA-binding protein 7 (CHD7) is essential for maintaining neural stem/progenitor cell (NSC) quiescence. CHD7 inactivation in adult NSCs results in a loss of stem cell quiescence in the hippocampus, a transient increase in cell divisions, followed by a significant decline in neurogenesis. [Stem Cells] Abstract

Spinal Cord Injury Enables Aromatic L-Amino Acid Decarboxylase Cells to Synthesize Monoamines
Investigators show by immunohistochemical techniques that cells containing the enzyme aromatic L-amino acid decarboxylase (AADC) occur not only near the central canal, but also in the intermediate zone and dorsal horn of the spinal gray matter. Following complete transection of the rat spinal cord at S2 level, they show that AADC cells distal to the lesion acquire the ability to produce serotonin from its immediate precursor,
5-hydroxytryptophan. [J Neurosci]

Neurotensin Signaling Regulates Stem-Like Traits of Glioblastoma Stem Cells through Activation of
IL-8/CXCR1/STAT3 Pathway

Scientists previously found that neurotensin and its primary receptor NTSR1 play a crucial role in glioblastoma cell proliferation and invasion. Now they show that NTSR1 is higher expressed in glioblastoma stem cells (GSCs) than their non-GSC counterparts. [Cell Signal] Abstract

CRM197 in Combination with shRNA Interference of VCAM-1 Displays Enhanced Inhibitory Effects on Human Glioblastoma Cells
Researchers investigated the role and mechanism of CRM197 combined with shRNA interference of vascular cell adhesion molecule-1 (VCAM-1) on the migration, invasion and apoptosis of glioblastoma cells. [J Cell Physiol] Abstract

Migration and Differentiation of Neural Progenitor Cells after Recurrent Laryngeal Nerve Avulsion in Rats
Scientists investigated migration and differentiation of neural progenitor cells from the ependymal layer to the nucleus ambiguus after recurrent laryngeal nerve avulsion. [PLoS One] Full Article

EGCG Inhibits Properties of Glioma Stem-Like Cells and Synergizes with Temozolomide through Downregulation of P-Glycoprotein Inhibition
Investigators examined the molecular mechanisms by which epigallocatechin gallate (EGCG), a bioactive polyphenol in green tea, inhibits the stem cell characteristics of glioma stem-like cells and synergizes with temozolomide, a DNA-methylating agent commonly used as first-line chemotherapy in gliomas. [J Neurooncol] Abstract

Reversal of Cellular Phenotypes in Neural Cells Derived from Huntington’s Disease Monkey-Induced Pluripotent Stem Cells
Scientists report the establishment of neural progenitor cell lines derived from induced pluripotent stem cells of transgenic Huntington’s disease (HD) monkeys. Upon differentiation to neurons, HD neural cells develop cellular features of HD, including the formation of nuclear inclusions and oligomeric mutant huntingtin protein aggregates, as well as increased apoptosis.

REVIEWS
The Role of Glial Cells and the Complement System in Retinal Diseases and Alzheimer’s Disease: Common Neural Degeneration Mechanisms
The authors discuss the common roles of the complement system (an immunological system) and glial cells (providing, amongst other functions, trophic support to neurons) in three disorders: age-related macular degeneration, glaucoma and Alzheimer’s disease. [Exp Brain Res] Abstract
