    Calcium Imaging of Neuronal Activity under Gradually Changing Odor Stimulation in Caenorhabditis elegans
    Authors:  Yuki Tanimoto and Koutarou D. Kimura, date: 01/05/2021, view: 336, Q&A: 0
    [Abstract]

    Olfactory behavior is among the most fundamental animal behaviors both in the wild and in the laboratory. To elucidate the neural mechanisms underlying olfactory behavior, it is critical to measure neural responses to odorant concentration changes resembling those that animals actually sense during olfactory behavior. However, reproducing the

    Optimized Immunostaining of Embryonic and Early Postnatal Mouse Brain Sections
    Authors:  Kawssar Harb, Michele Bertacchi and Michèle Studer, date: 01/05/2021, view: 623, Q&A: 0
    [Abstract]

    The mammalian neocortex, the outer layer of the cerebrum and most recently evolved brain region, is characterized by its unique areal and laminar organization. Distinct cortical layers and areas can be identified by the protein expression of graded transcription factors and molecular determinants that define the identity of different projection

    A Parkinson’s Disease-relevant Mitochondrial and Neuronal Morphology High-throughput Screening Assay in LUHMES Cells
    [Abstract]

    Parkinson’s disease is a devastating neurodegenerative disorder affecting 2-3% of the population over 65 years of age. There is currently no disease-modifying treatment. One of the predominant pathological features of Parkinson’s disease is mitochondrial dysfunction, and much work has aimed to identify therapeutic compounds which can

    Whole-mount Immunohistochemistry of Adult Zebrafish Retina for Advanced Imaging
    Authors:  Mikiko Nagashima and Peter F. Hitchcock, date: 12/20/2020, view: 615, Q&A: 0
    [Abstract]

    Immunohistochemistry is a widely used technique to examine the expression and subcellular localization of proteins. This technique relies on the specificity of antibodies and requires adequate penetration of antibodies into tissues. The latter is especially challenging for thick specimens, such as embryos and other whole-mount preparations. Here

    Use of Optogenetic Amyloid-β to Monitor Protein Aggregation in Drosophila melanogaster, Danio rerio and Caenorhabditis elegans
    [Abstract]

    Alzheimer’s Disease (AD) has long been associated with accumulation of extracellular amyloid plaques (Aβ) originating from the Amyloid Precursor Protein. Plaques have, however, been discovered in healthy individuals and not all AD brains show plaques, suggesting that extracellular Aβ aggregates may play a smaller role than

    In vitro Time-lapse Imaging of Primary Cilium in Migrating Neuroblasts
    [Abstract] Neuronal migration is a critical step for the development of neuronal circuits in the brain. Immature new neurons (neuroblasts) generated in the postnatal ventricular-subventricular zone (V-SVZ) show a remarkable potential to migrate for a long distance at a high speed in the postnatal mammalian brain, and are thus a powerful model to analyze the ...
    Serial Cryomicrotomy of Saccharomyces cerevisiae for Serial Electron Cryotomography
    Authors:  Cai Tong Ng, Mark S. Ladinsky and Lu Gan, date: 11/20/2020, view: 627, Q&A: 0
    [Abstract] Electron cryotomography (cryo-ET) is an increasingly popular technique to study cellular structures and macromolecules in situ. Due to poor penetration of electrons through thick biological samples, the vitreously frozen samples for cryo-ET need to be thin. For frozen-hydrated cells, such samples can be produced either by cryomicrotomy or ...
    Super-resolution Imaging of the T cell Central Supramolecular Signaling Cluster Using Stimulated Emission Depletion Microscopy
    Authors:  Sin Lih Tan, Dominic Alibhai, Stephen J. Cross, Harry Thompson and Christoph Wülfing, date: 11/05/2020, view: 579, Q&A: 0
    [Abstract]

    Supramolecular signaling assemblies are of interest for their unique signaling properties. A µm scale signaling assembly, the central supramolecular signaling cluster (cSMAC), forms at the center interface of T cells activated by antigen presenting cells (APC). The adaptor protein linker for activation of T cells (LAT) is a key cSMAC component.

    Live-cell Imaging and Quantitative Analysis of Meiotic Divisions in Caenorhabditis elegans Males
    Authors:  Gunar Fabig, Falko Löffler, Christian Götze and Thomas Müller-Reichert, date: 10/20/2020, view: 579, Q&A: 0
    [Abstract] Live-imaging of meiotic cell division has been performed in extracted spermatocytes of a number of species using phase-contrast microscopy. For the nematode Caenorhabditis elegans, removal of spermatocytes from gonads has damaging effects, as most of the extracted spermatocytes show a high variability in the timing of meiotic divisions or ...
    Real-time Three-dimensional Tracking of Endocytic Vesicles
    Authors:  Stephanie Duhamel and Kossay Zaoui, date: 10/20/2020, view: 728, Q&A: 0
    [Abstract] Endocytic trafficking and recycling are fundamental cellular processes that control essential functions such as signaling protein complexes transport and membrane identity. The small GTPase Rabs are indispensable component of the endosomal recycling machinery. The Rabs bind to effectors to mediate their functions, such as protein sorting and ...
