SCIENCE NEWS Neurological Protein May Hold the Key to New Treatments for Depression Neuroscientists have developed a protein peptide that may be a novel type of highly targeted treatment for depression with a low side-effect profile. [Press release from the Centre for Addiction and Mental Health discussing online prepublication in Nature Medicine] Brain Scans Show Effects of Parkinson’s Drug Neuroscientists using a new brain imaging technique could see an investigational drug for Parkinson’s disease get into a patient’s brain and affect blood flow in several key structures, an indicator the drug may be effective. [Press release from Washington University in St. Louis discussing online prepublication in The Journal of Neuroscience] Gene Therapy Prevents Memory Problems in Mice with Alzheimer’s Disease Scientists have discovered a new strategy to prevent memory deficits in a mouse model of Alzheimer’s disease (AD). Humans with AD and mice genetically engineered to simulate the disease have abnormally low levels of an enzyme called EphB2 in memory centers of the brain. Improving EphB2 levels in such mice by gene therapy completely fixed their memory problems. [Press release from EurekAlert! discussing online prepublication in Nature] Novel Method Results in Promising Drugs for Huntington’s Disease (HD) Therapeutics Buck Institute, Yale University and University of California, Berkeley scientists identify three caspase inhibitors that block HD-associated neuronal damage in cell culture; follow up experiments are underway in mice. [Press release from The Buck Institute for Age Research discussing online prepublication in Chemistry and Biology] Study Reveals Neural Basis of Rapid Brain Adaptation A new study details the biological basis of this ability for rapid adaptation: neurons located at the beginning of the brain’s sensory information pathway that change their level of simultaneous firing. [Press release from Georgia Institute of Technology discussing online prepublication in Nature Neuroscience] Harvard Scientists Reverse Aging in Mice The mice had a telomerase gene that could be toggled on and off. When the gene was turned off, the mice aged rapidly. But when the team turned the gene back on, the aging process of the mice reversed. The mice’s worn-out organs were physically regenerated. The result was that shrunken brains increased in size, the neural stem cell reserves were replenished, and coat hair was restored to a healthy sheen. [Press release from The Harvard Crimson discussing online prepublication in Nature] Researchers Say Stability Is Step Toward Treating ALS A team of Brandeis scientists reports an innovative approach to treating the most common form of familial Amyotrophic Lateral Sclerosis (ALS). In the study, researchers studied mutations in the gene that makes a particular protein, known as SOD1, responsible for causing much of the familial form of ALS.

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)
Reversing EphB2 Depletion Rescues Cognitive Functions in Alzheimer Model To determine the pathogenic importance of EphB2 depletions in Alzheimer’s disease and related models, researchers used lentiviral constructs to reduce or increase neuronal expression of EphB2 in memory centers of the mouse brain. [Nature] Tumour Vascularization via Endothelial Differentiation of Glioblastoma Stem-Like Cells Here researchers show that a variable number (range 20-90%, mean 60.7%) of endothelial cells in glioblastoma carry the same genomic alteration as tumour cells, indicating that a significant portion of the vascular endothelium has a neoplastic origin. [Nature] Telomerase Reactivation Reverses Tissue Degeneration in Aged Telomerase-Deficient Mice Notably, somatic telomerase reactivation reversed neurodegeneration with restoration of proliferating Sox2(+) neural progenitors, Dcx(+) newborn neurons, and Olig2(+) oligodendrocyte populations. [Nature] Siah Regulation of Pard3A Controls Neuronal Cell Adhesion During Germinal Zone Exit Researchers found that cerebellar granule neuron germinal zone exit is regulated by proteasomal degradation of Pard3A by the Seven in Absentia homolog (Siah) E3 ubiquitin ligase. [ Science] Uncoupling the Dopamine D1-D2 Receptor Complex Exerts Antidepressant-Like Effects Researchers report that coupling between dopamine D1 and D2 receptors was markedly increased in postmortem brain of subjects suffering from major depression. [Nat Med] Thalamic Synchrony and the Adaptive Gating of Information Flow to Cortex The results here suggest a shift in coding strategy with adaptation that directly controls information relayed to cortex, which could have implications for encoding velocity signatures of textures. [Nat Neurosci] Strategies for Stabilizing Superoxide Dismutase (SOD1), the Protein Destabilized in the Most Common Form of Familial Amyotrophic Lateral Sclerosis (ALS) The results demonstrate that targeting the cysteine residues is an important new strategy for development of ALS therapies. [Proc Natl Acad Sci USA] Quantification of Indirect Pathway Inhibition by the Adenosine A(2a) Antagonist SYN115 in Parkinson Disease Researchers conclude that (1) SYN115 enters the brain and exerts dose-dependent regional effects, (2) the most prominent of these effects is consistent with deactivation of the indirect pathway as predicted by preclinical studies; and (3) perfusion MRI can provide rapid, quantitative, clinically relevant dose-finding information for pharmaceutical development. [J Neurosci] Identification and Evaluation of Small Molecule Pan-Caspase Inhibitors in Huntington’s Disease (HD) Models In this study, the identified nonpeptidic caspase inhibitors were used to confirm the role of caspase-mediated huntingtin proteolysis in HD. These results further implicate caspases as promising targets for HD therapeutic development. [Chem Biol] Dlxin-1, a Member of MAGE Family, Inhibits Cell Proliferation, Invasion and Tumorigenicity of Glioma Stem Cells Using the cancer stem cell hypothesis, which attributes the initiation and progression of brain tumors to the cancer-initiating stem cells, researchers have investigated the role of Dlxin-1 in the glioma stem cells propagated by us as a cell culture system comprising of HNGC-2 cells.
