    Optimized Immunostaining of Embryonic and Early Postnatal Mouse Brain Sections
    Authors:  Kawssar Harb, Michele Bertacchi and Michèle Studer, date: 01/05/2021, view: 565, Q&A: 0

    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

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

    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 ...
    Real-time Three-dimensional Tracking of Endocytic Vesicles
    Authors:  Stephanie Duhamel and Kossay Zaoui, date: 10/20/2020, view: 721, 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 ...
    Co-immunostaining of ICAM-1, ICAM-2, and CD31 in Mouse Kidney Glomeruli
    Author:  Sun-sang J. Sung, date: 07/05/2020, view: 1059, Q&A: 0
    [Abstract] Glomerulonephritis (GN) is a common pathological condition in chronic kidney diseases that often leads to end stage renal failure. Mac-1 (CD11b/CD18)-mediated neutrophil, macrophage, and dendritic cell glomerular infiltration leading to cellular dysfunction and destruction is an important disease mechanism. The cellular distribution and dynamics ...
    Maintenance and Quantitative Phenotyping of the Oomycete-plant Model Pathosystem Hyaloperonospora arabidopsidisArabidopsis
    Authors:  Fang-Yu Hwu and Martin Parniske, date: 06/20/2020, view: 1190, Q&A: 0
    [Abstract] The interaction between the host plant Arabidopsis thaliana (Arabidopsis) and the oomycete Hyaloperonospora arabidopsidis (Hpa) is an established model system for the study of an obligate biotrophic downy mildew interaction. The evaluation of the developmental success of Hpa is often based on the quantification ...
    Quantitative Nucleocytoplasmic Transport Assays in Cellular Models of Neurodegeneration
    Authors:  Joni Vanneste, Thomas Vercruysse, Philip Van Damme, Ludo Van Den Bosch and Dirk Daelemans, date: 06/20/2020, view: 1288, Q&A: 0
    [Abstract] Nucleocytoplasmic transport deficits are suggested to play a role in neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). Given the importance and complexity of this process, understanding when these aberrations occur and which pathways are involved is of great importance. Here, we make use of CRISPR-Cas9 technology to ...
    Spatial Image Correlation Spectroscopy (ICS): A Technique for Average Size Determination of Subcellular Accumulated Structures from Fluorescence Microscopic Images
    Authors:  Akira Kitamura and Masakata Kinjo, date: 05/20/2020, view: 1351, Q&A: 0
    [Abstract] Size determination of subcellular structures such as inclusion bodies (IBs) and granules from fluorescent images is important for identification and structural characterization. However, it is often time-consuming just for the comparison of the average size of the structures. Here, we introduce a high-throughput procedure to represent the average ...
    Live Cell Imaging of Male Meiosis in Arabidopsis by a Landmark-based System
    [Abstract] Live cell imaging has tremendously promoted our understanding of cellular and subcellular processes such as cell division. Here, we present a step-by-step protocol for a robust and easy-to-use live cell imaging approach to study male meiosis in the plant Arabidopsis thaliana as recently established. Our method relies on the concomitant ...
    Bimolecular Fluorescence Complementation (BiFC) for Studying Sarcomeric Protein Interactions in Drosophila
    Authors:  Océane Marescal, Frieder Schöck and Nicanor González-Morales, date: 04/05/2020, view: 1757, Q&A: 0
    [Abstract] Protein-protein interactions in Drosophila myofibrils are essential for their function and formation. Bimolecular Fluorescence Complementation (BiFC) is an effective method for studying protein interactions and localization. BiFC relies on the reconstitution of a monomeric fluorescent protein from two half-fragments when in proximity. Two ...
