    A Multi-color Bicistronic Biosensor to Compare the Translation Dynamics of Different Open Reading Frames at Single-molecule Resolution in Live Cells
    Authors:  Amanda L. Koch, Tatsuya Morisaki and Timothy J. Stasevich, date: 07/20/2021, view: 49, Q&A: 0

    Here, we describe how to image and quantitate the translation dynamics of a bicistronic biosensor that we recently created to fairly compare cap-dependent and IRES-mediated translation at single-molecule resolution in live human cells. This

    Isolation of Microglia and Analysis of Protein Expression by Flow Cytometry: Avoiding the Pitfall of Microglia Background Autofluorescence
    Authors:  Jeremy C. Burns, Richard M. Ransohoff and Michaël Mingueneau, date: 07/20/2021, view: 56, Q&A: 0

    Microglia are a unique type of tissue-resident innate immune cell found within the brain, spinal cord, and retina. In the healthy nervous system, their main functions are to defend the tissue against infectious microbes, support neuronal networks

    Modeling the Nonlinear Dynamics of Intracellular Signaling Networks
    Authors:  Oleksii S. Rukhlenko and Boris N. Kholodenko, date: 07/20/2021, view: 65, Q&A: 0

    This protocol illustrates a pipeline for modeling the nonlinear behavior of intracellular signaling pathways. At fixed spatial points, nonlinear signaling dynamics are described by ordinary differential equations (ODEs). At constant parameters,

    Analysis of the Effects of Hexokinase 2 Detachment From Mitochondria-Associated Membranes with the Highly Selective Peptide HK2pep
    Authors:  Francesco Ciscato, Federica Chiara, Riccardo Filadi and Andrea Rasola, date: 07/20/2021, view: 65, Q&A: 0

    The crucial role of hexokinase 2 (HK2) in the metabolic rewiring of tumors is now well established, which makes it a suitable target for the design of novel therapies. However, hexokinase activity is central to glucose utilization in all tissues;

    Preparation of Human Chondrocytes for Profiling Using Cytometry by Time-of-flight (cyTOF)
    Authors:  Fiorella Carla Grandi and Nidhi Bhutani, date: 07/20/2021, view: 64, Q&A: 0

    Single-cell technologies have allowed high-resolution profiling of tissues and thus a deeper understanding of tissue homeostasis and disease heterogeneity. Understanding this heterogeneity can be especially important for tailoring treatments in a

    Spatiotemporal Quantification of Cytosolic pH in Arabidopsis Pollen Tubes
    Authors:  Maria Teresa Portes, Daniel S.C. Damineli and José A. Feijó, date: 07/20/2021, view: 123, Q&A: 0

    Ion-specific probes and fluorescent indicators have been key in establishing the role of ion signaling, namely calcium, protons, and anions, in plant development, providing a robust approach for monitoring spatiotemporal changes in intracellular ion

    Ethanol-induced Sedative Behavior: An Assay to Investigate Increased Dopamine Signaling in Caenorhabditis elegans
    Authors:  Anuradha Singh, Kavita Babu and Pratima Pandey, date: 07/05/2021, view: 602, Q&A: 0

    Dopamine (DA) signaling affects locomotion, feeding, learning, and memory in C. elegans. Various assays have been developed to study the proteins involved in these behaviors; however, these assays show behavioral output only when there is a drastic

    Electron Tomography to Study the Three-dimensional Structure of the Reovirus Egress Pathway in Mammalian Cells

    Mammalian orthoreoviruses (reoviruses) are nonenveloped, double-stranded RNA viruses that replicate and assemble in cytoplasmic membranous organelles called viral inclusions (VIs). To define the cellular compartments involved in nonlytic reovirus

    A Method for Estimating the Potential Synaptic Connections Between Axons and Dendrites From 2D Neuronal Images
    Authors:  Carolina Tecuatl, Diek W. Wheeler and Giorgio A. Ascoli, date: 07/05/2021, view: 1254, Q&A: 0

    Computational neuroscience aims to model, reproduce, and predict network dynamics for different neuronal ensembles by distilling knowledge derived from electrophysiological and morphological evidence. However, analyses and simulations often remain

    Production, quantification, and infection of Amazonian Phlebovirus (Bunyaviridae)

    Phlebotomine vectors, sand flies of the order Diptera, are known to transmit Leishmania parasites as well as RNA viruses (arboviruses) to humans. The arbovirus, Icoaraci Phlebovirus (BeAN 24262 - ICOV), used in this study was isolated from Nectomys
