A Nanoscale Interface Promoting Molecular and Functional Differentiation of Neural Cells

Here’s a new open-access paper in Scientific Reports detailing the use of Hydrotalcite-like compounds (HTlc) as nanostructured interfaces that are biocompatible with astrocytes in vitro. The use of nanostructured interfaces allows researchers to exert control of cellular behavior at several different scales. HTlc films favor astrocyte differentiation by inducing vinculin polarization and F-actin fiber alignment. This was assessed in part by imaging immunofluorescence with Nikon ECLIPSE 80i and TE-2000U research microscopes.

US Grants for Zebrafish Studies on the Rise

A new assessment by the National Institutes of Health (NIH) Office of Portfolio Analysis has found that the popularity of zebrafish as model organisms rose by approximately 60% from 2008 to 2015, marking a shift in model organism trends. This was determined by data mining of successful R01 awards from that period, which found zebrafish mentioned in over 9500 successful grant applications.

A Far-red Fluorescent Protein Evolved from a Cyanobacterial Phycobiliprotein

A team of researchers have developed a new far-red fluorescent protein (FP): smURFP. This new FP variant has 642 nm excitation and 670 nm emission peaks, an extinction coefficient of 180,000 M−1cm, quantum yield of 18%, and comparable photostability to EGFP. Previous FPs in this spectral class were based upon bacteriophytochromes, but smURFP is part of a new class of FPs evolved from an allophycocyanin alpha-subunit. Such far-red FPs are popular for imaging in live animals because of reduced scattering and absorption.

Imaging the Brain at Multiple Size Scales

Over the past decade big advances have been made in optical ‪#microscopy‬ for seeing very small details. Recently, Expansion Microscopy has been introduced for imaging such fine detail by making small samples bigger. ‪MIT scientists use this new method to image entire tissues, such as whole mouse brains, by swelling them to over 4x their original size.

NIH Plans To Lift Ban On Research Funds For Part-Human, Part-Animal Embryos

The National Institutes of Health (NIH) is advancing a new policy to allow the use of federal money to make chimeras – organisms with two or more genetically distinct populations of cells, including those of different species. There are many possible applications for chimeras, including the use of part-human chimeras as animal models for disease. Extra care is being taken to try to address possible ethical concerns.

Strain and Rate-dependent Neuronal Injury in a 3D in vitro Compression Model of Traumatic Brain Injury

Researchers at Brown University have developed a new in vitro model for assessing neuronal injury due to impact tissue strain, as experienced during traumatic brain injury. Injury is simulated in a 3D neuronal culture using a voice coil actuator mounted on a Nikon A1 confocal microscope, allowing for quantification of neuronal lifetime, pathomorphology, and viability with high spatiotemporal accuracy before, during, and after injury. The results are expected to be of high importance for developing future mitigation and diagnosis programs. Article is open access

Ultra-High Resolution 3D Imaging of Whole Cells

Check out this new open-access resource article from researchers at Yale University detailing a 4Pi single molecule localization microscope with isotropic localization precision of ~10-20 nm. Importantly this new nanoscope can be used to image samples up to 10 um thick, a significant improvement over previous two-objective localization microscopy approaches. This is made possible by using deformable mirrors to correct for depth-induced changes in the shape of the point-spread function.

An Optogenetic System for Photoinduced Protein Dissociation

A new method has been introduced for light-induced protein dissociation, termed LOVTRAP. This optogenetic approach uses a mutant z subunit of protein A, named Zdk, which binds to a light-oxygen-voltage-sensing domain (LOV2) with precise kinetics. Binding occurs in the dark, with over a 150-fold rise in the dissociation constant upon excitation with blue light. The authors demonstrate reversible sequestration of multiple proteins of interest (POI) to the mitochondrial outer membrane by anchoring LOV2 to mitochondria and fusing the POI to Zdk.
