    Heterochronic Phenotype Analysis of Hypodermal Seam Cells in Caenorhabditis elegans
    Authors:  Yon Ju Ji and Jiou Wang, date: 01/05/2019, view: 139, Q&A: 0
    [Abstract] Heterochrony refers to changes in the timing of developmental events, and it is precisely regulated in the organisms by the heterochronic genes such as C. elegans lin-4 and let-7. Mutations in these genes cause precocious or retarded development of certain cell lineages. With well-defined cell lineages, C. elegans ...
    Adoptive Transfer of Monocytes Sorted from Bone Marrow
    Authors:  Damya Laoui, Eva Van Overmeire, Chloé Abels, Jiri Keirsse and Jo A Van Ginderachter, date: 01/05/2019, view: 200, Q&A: 0
    [Abstract] Inflammatory Ly6Chi monocytes can give rise to distinct mononuclear myeloid cells in the tumor microenvironment, such as monocytic myeloid-derived suppressor cells (Mo-MDSC), immature macrophages, M2-like tumor-associated macrophages (TAMs), M1-like TAMs or monocyte-derived dendritic cells (Mo-DCs). This protocol describes a method to ...
    Variable Dose Analysis: A Novel High-throughput RNAi Screening Method for Drosophila Cells
    Authors:  Katarzyna Sierzputowska, Chris R. Baxter and Benjamin E. Housden, date: 12/20/2018, view: 311, Q&A: 0
    [Abstract] Genetic screens are a powerful approach to identify previously uncharacterized genes involved in specific biological processes. Several technologies have been developed for high-throughput screens using reagents such as RNAi or CRISPR, and each approach is associated with specific advantages and disadvantages. Variable Dose Analysis (VDA), is an ...
    Ultrasound Guided Intra-thymic Injection to Track Recent Thymic Emigrants and Investigate T Cell Development
    [Abstract] To track recent thymic emigrants (RTEs) or study T cell development in the thymus, intra-thymic injection of a cellular tag or precursor cells for various T cell lineages is often desired. However, the traditional surgical approach to expose the thymus for intra-thymic injection is time-consuming and can cause a high level of pain and stress to ...
    In-vivo gp100-specific Cytotoxic CD8+ T Cell Killing Assay
    [Abstract] Cytotoxic CD8+ T lymphocytes (CTLs) represent a crucial component of the adaptive immune system and play a prominent role in the anti-tumor immune responses of both mice and humans.

    Cytotoxic CD8+ T cells are responsible for the lysis of cells expressing peptides associated with MHC class I molecules and derived ...
    Papain-based Single Cell Isolation of Primary Murine Brain Endothelial Cells Using Flow Cytometry
    Authors:  Hanadie Yousef, Cathrin J Czupalla, Davis Lee, Eugene C Butcher and Tony Wyss-Coray, date: 11/20/2018, view: 449, Q&A: 0
    [Abstract] Brain endothelial cells (BECs) form the integral component of the blood-brain barrier (BBB) which separates the systemic milieu from the brain parenchyma and protects the brain from pathogens and circulating factors. In order to study BEC biology, it was of particular interest to establish a method that enables researchers to investigate and ...
    Electroporation of Labeled Antibodies to Visualize Endogenous Proteins and Posttranslational Modifications in Living Metazoan Cell Types
    Authors:  Sascha Conic, Dominique Desplancq, László Tora and Etienne Weiss, date: 11/05/2018, view: 372, Q&A: 0
    [Abstract] The spatiotemporal localization of different intracellular factors in real-time and their detection in live cells are important parameters to understand dynamic protein-based processes. Therefore, there is a demand to perform live-cell imaging and to measure endogenous protein dynamics in single cells. However, fluorescent labeling of endogenous ...
    HIVGKO: A Tool to Assess HIV-1 Latency Reversal Agents in Human Primary CD4+ T Cells
    Authors:  Emilie Battivelli and Eric Verdin, date: 10/20/2018, view: 450, Q&A: 0
    [Abstract] While able to suppress HIV replication in HIV infected individuals, combination antiretroviral therapy (ART) fails to eliminate viral latent reservoir, which consists in integrated transcriptional silenced HIV provirus. So far, identification of latently-infected cells has relied on activating cells to induce expression of HIV proteins which can ...
    Transcytosis Assay for Transport of Glycosphingolipids across MDCK-II Cells
    Authors:  Maria Daniela Garcia-Castillo, Wayne I. Lencer and Daniel J.-F. Chinnapen, date: 10/20/2018, view: 363, Q&A: 0
    [Abstract] Absorption and secretion of peptide and protein cargoes across single-cell thick mucosal and endothelial barriers occurs by active endocytic and vesicular trafficking that connects one side of the epithelial or endothelial cell (the lumen) with the other (the serosa or blood). Assays that assess this pathway must robustly control for non-specific ...
    Activation of Fibroblast Contractility via Cell-Cell Interactions and Soluble Signals
    Authors:  Neha Pincha, Dyuti Saha, Tanay Bhatt, Ravindra K. Zirmire and Colin Jamora, date: 09/20/2018, view: 644, Q&A: 0
    [Abstract] The collagen contraction assay is an in vitro, three-dimensional method to determine the factor(s) affecting the contractile behavior of activated cells such as fibroblasts in either physiological or pathological scenarios. The collagen lattices/hydrogels are seeded with fibroblasts to mimic the interactions between these cells and their ...
