    Authors:  Amanda L. Koch, Tatsuya Morisaki and Timothy J. Stasevich, date: 07/20/2021, view: 811, Q&A: 0
    [Abstract]

    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 technique employs a pair of complementary intrabodies loaded into living cells that co-translationally bind

    [Abstract]

    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 through synapse remodeling, and clear extracellular debris and dying cells through phagocytosis.

    Authors:  Oleksii S. Rukhlenko and Boris N. Kholodenko, date: 07/20/2021, view: 888, Q&A: 0
    [Abstract]

    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, these ODEs may have multiple attractors, such as multiple steady states or limit cycles. Standard

    [Abstract]

    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; thus, enzymatic inhibition of HK2 can induce severe adverse effects. In an effort to find a selective

    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: 659, Q&A: 0
    [Abstract]

    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 change in DA levels. We designed an assay capable of observing behavioral output even with only

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

    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 egress, we imaged viral egress in infected, nonpolarized human brain microvascular endothelial cells

    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: 1323, Q&A: 0
    [Abstract]

    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 critically limited by the sparsity of direct experimental constraints on essential parameters, such

    Production, quantification, and infection of Amazonian Phlebovirus (Bunyaviridae)
    [Abstract]

    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 rodents, a mammalian species that is the same natural sylvatic reservoir of Leishmania (Leishmania)
