PUBLICATIONS(Ranked by impact factor of the journal)Defining the Adult Neural Stem Cell Niche Proteome Identifies Key Regulators of Adult Neurogenesis Researchers leveraged the spatial separation of the sub-ependymal zone neural stem cell niche and the olfactory bulb, and presented a comprehensive proteomic characterization of these regions in comparison to the cerebral cortex. [Cell Stem Cell] Full Article | Graphical Abstract Imprinted Maternally Expressed MicroRNAs Antagonize Paternally Driven Gene Programs in Neurons Investigators functionally characterized a large cluster of microRNAs expressed from the maternally inherited allele to explore the molecular and cellular consequences of imprinted miRNA activity. [Mol Cell] Abstract | Graphical Abstract Glial Cell Diversity and Methamphetamine-Induced Neuroinflammation in Human Cerebral Organoids Scientists analyzed 20,758 cells from eight untreated and six methamphetamine-treated cerebral organoids and found that the organoids developed from embryonic stem cells contained a diverse array of glial and neuronal cell types. [Mol Psychiatry] Full Article Small-Molecule G-Quadruplex Stabilizers Reveal a Novel Pathway of Autophagy Regulation in Neurons Using an in vitro assay, the authors showed that a putative G-quadruplex-forming sequence in the first intron of the Atg7 gene folded into a G4. [eLife] Full Article Researchers revealed that satellite glial cells (SGCs) were enriched in genes related to the immune system and cell-to-cell communication. Analysis of SGC transcriptional changes in a nerve injury-paradigm revealed a differential response at three-days versus 14-days postinjury. [Glia] Abstract The authors investigated the impact of culturing determinants on several parameters such as neuronal survival, total dendritic length, dendritic endpoints, soma size, cell clusterization, spontaneous activity. [Sci Rep] Full Article Investigators compared acutely isolated retinal ganglion cells (RGCs) at various developmental stages and RGCs differentiated in vitro from embryonic retinal progenitors for the effects of aging. [Sci Rep] Full Article Scientists investigated the effect of the proinflammatory cytokines TNF-α, IL-1β and IL-6 on the interplay between amyloid precursor protein (APP) processing and release of heparan sulfate from Gpc-1 in neuronal cells. [Glycobiology] Abstract Researchers identified hundreds of secreted proteins in conditioned media from in vitro adult mouse hippocampal neural stem and progenitor cells using an antibody array and mass spectrometry.

INDUSTRY NEWSAlkahest, Inc. announced the dosing of the first patient in a Phase II clinical trial of AKST4290, an orally administered CCR3 inhibitor, for treatment of Parkinson’s disease. The trial, AKST4290-211, is funded in part by The Michael J. Fox Foundation for Parkinson’s Research and will evaluate the effect of AKST4290 on motor function and activities of daily living in patients with Parkinson’s disease. [Alkahest, Inc.] Press Release The Sanofi Phase IIb study evaluating its investigational Bruton’s tyrosine kinase (BTK) inhibitor, an oral, brain-penetrant, selective small molecule, achieved its primary endpoint.

POLICY NEWSFDA Now Allows Certain Lab Animals to Be Retired and Adopted The US Food and Drug Administration will now permit certain animals used in experiments to retire and be adopted rather than face euthanasia, according to internal documents reviewed by The Hill. Although the policy changed in November, there have not been any public statements from the agency. [The Scientist] Editorial Trump Proposes Significant Cuts to NIH for 2021 Budget The president’s request for next year’s federal budget includes a seven percent drop in funding for the National Institutes of Health and reductions for other science agencies.
