TOP STORYThe Joy of Neurons: A Simplified ‘Cookbook’ for Engineering Brain Cells to Study Disease Scientists devised what they call a “neuronal cookbook” for turning skin cells into different types of neurons. The research opens the door to studying common brain conditions such as autism, schizophrenia, addiction and Alzheimer’s disease under reproducible conditions in a dish.

PUBLICATIONS(Ranked by impact factor of the journal)Single-cell RNA-seq revealed that ependymal cells are enriched for cilia-related genes and share several stem-cell-associated genes with neural stem or progenitors. Under in vivo and in vitro neural-stem- or progenitor-stimulating environments, ependymal cells failed to demonstrate any suggestion of latent neural-stem-cell function. [Cell] Abstract | Press Release | Graphical Abstract The authors report a comprehensive and efficient differentiation paradigm for human induced pluripotent stem cells that generate multiple CA3 pyramidal neuron subtypes as detected by single-cell RNA sequencing. [Cell Stem Cell] Abstract | Graphical Abstract Investigators demonstrated that syngeneic porcine induced pluripotent stem cell (iPSC)-derived neural precursor cell transplantation to the spinal cord in the absence of immunosuppression is associated with long-term survival and neuronal and glial differentiation. [Sci Transl Med] Abstract | Press Release Researchers demonstrated in cortical neurons that a single cue is sufficient for dendritic filopodia to reject or select specific axonal contacts for elaboration as synaptic sites. [Neuron] Abstract | Graphical Abstract Scientists showed that RNF12 catalytic activity is required for proper stem cell maintenance and neural differentiation, and this is disrupted by patient-associated X-linked intellectual disability mutation. [Cell Rep] Full Article | Graphical Abstract CDK5 Inhibition Resolves PKA/cAMP-Independent Activation of CREB1 Signaling in Glioma Stem Cells Pharmaceutical inhibition of CDK5 prevents glioma stem cell self-renewal in vitro and in xenografted tumors, at least partially by suppressing CREB1 activation independently of PKA/cAMP. [Cell Rep] Full Article | Graphical Abstract GPR158 promoted glioma stem cell differentiation and induced apoptosis and was highest expressed in the cerebral cortex and in oligodendrogliomas, lower in IDH mutant astrocytomas and lowest in the most malignant form of glioma, IDH wild-type glioblastoma. [Oncogene] Full Article Loss of MECP2 Leads to Activation of P53 and Neuronal Senescence To determine the role for mutations of MECP2 in Rett syndrome, investigators generated isogenic lines of human induced pluripotent stem cells, neural progenitor cells, and neurons from patient fibroblasts with and without MECP2 expression in an attempt to recapitulate disease phenotypes in vitro. [Stem Cell Reports] Full Article Antibody-Antisense Oligonucleotide Conjugate Downregulates a Key Gene in Glioblastoma Stem Cells The authors developed antibody-antisense oligonucleotide (AON) conjugates to target and reduce DRR/FAM107A expression. [Mol Ther Nucleic Acids] Full Article Researchers found that a novel compound, N2‐(4‐isopropylphenyl)‐5‐(3‐methoxyphenoxy)quinazoline‐2,4‐diamine, enhanced the self‐renewal capability of neural stem cells in vitro and in vivo. [Stem Cells] Abstract Investigators created and characterized two new glioblastoma cell lines resistant to temozolomide (TMZ) in vitro, based on the 8MGBA and 42MGBA cell lines. Analysis of the TMZ resistant variants in conjunction with their parental, sensitive cell lines showed that acquisition of TMZ resistance is accompanied by broad phenotypic changes, including increased proliferation, migration, chromosomal aberrations, and secretion of cytosolic lipids. [Sci Rep] Full Article Scientists report a 3D spheroid model of the blood brain barrier comprising all major cell types, including neurons, microglia and oligodendrocytes, to recapitulate more closely normal human brain tissue.

SCIENCE NEWSIn March 2017, the FDA approved ocrelizumab as the first treatment for both relapsing and progressive forms of MS. Neurologist Amit Bar-Or, MD, FRCPC, chief of the Multiple Sclerosis division and director for the Center for Neuroinflammation and Experimental Therapeutics, presented findings from two studies that look more deeply into the impact of ocrelizumab in these patients. [Press release from University of Pennsylvania discussing research presented at the 2018 American Academy of Neurology (AAN) Annual Meeting, Los Angeles] Press Release BrainStorm Cell Therapeutics Inc. announced that Chaim Lebovits, president and CEO, will present data from the company’s Phase II clinical study of NurOwn® in ALS.

INDUSTRY NEWSFORMA Therapeutics and the University of Oxford announced that they have entered into a collaboration and license agreement to identify, validate and develop DUB inhibitors for the treatment of neurodegenerative diseases. [FORMA Therapeutics (Business Wire Inc.)] Press Release £18 Million Fund to Tackle Six Biggest Themes in Brain Tumor Research Launched The Cancer Research UK Brain Tumor Awards have been launched in partnership with The Brain Tumor Charity. The aim of the awards is to help advance the understanding about the biology of the disease and the challenges translating discoveries into treatments. [Cancer Research UK] Press Release Cure Brain Cancer Foundation launched its Capacity Building Program – a new initiative to rapidly increase brain cancer research capacity in Australia to more quickly find cures for the disease. The program will do so by encouraging more world-class researchers to work in brain cancer, while increasing the resources at their disposal, beginning with two new Infrastructure Grants. [Cure Brain Cancer Foundation] Press Release Biohaven Pharmaceutical Holding Company Ltd. announced that it has established an expanded access program with sublingual BHV-0223, an investigational drug candidate, for patients with ALS. [Biohaven Pharmaceutical Holding Company Ltd.] Press Release Neurotrope, Inc. announced that Neurotrope Bioscience, Inc., its wholly-owned operating subsidiary, has completed the study design for its confirmatory Phase II clinical trial in moderate to severe Alzheimer’s disease.

POLICY NEWSNIH’s Neuroscience Institute Will Limit Grants to Well-Funded Labs Big laboratories are back in the crosshairs at the National Institutes of Health (NIH). NIH’s neurological institute plans to pare back the number of investigators it supports who have $1 million or more in NIH grants. [ScienceInsider] Editorial Australian Budget Delivers for Science Facilities and Medical Research The government will push to invest almost Aus$1.9 billion (US$1.4 billion) over the next 12 years in shared research infrastructure — such as microscopes, supercomputers, a marine observing system and telescopes used in myriad disciplines, from nanotechnology to oceanography. Medical research will receive an increase of $1.3 billion, to be spent on various programs and initiatives over 10 years that improve health and boost the medical industry, including $500 million for a genomics and precision-medicine initiative. [Nature News] Editorial Animal Tests Surge under New U.S. Chemical Safety Law The cause of the increase isn’t clear. But the new law imposes stricter requirements on a broader array of chemicals than its predecessor, including both new products and ones already on the market, and experts say Environmental Protection Agency staff may be trying to comply by gathering more test data from companies.
