    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
    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 ...
    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 ...
    Eimeria vermiformis Infection Model of Murine Small Intestine
    [Abstract] Eimeria vermiformis is a tissue specific, intracellular protozoan that infects the murine small intestinal epithelia, which has been widely used as a coccidian model to study mucosal immunology. This mouse infection model is valuable to investigate the mechanisms of host protection against primary and secondary infection in the small ...
    Monitoring Natural Killer Cell Function in Human Ovarian Cancer Cells of Ascitic Fluid
    Authors:  Vikash Kumar and Asok Mukhopadhyay, date: 12/20/2018, view: 193, Q&A: 0
    [Abstract] Natural killer (NK) cells are the major effectors of the innate immune system when activated resulting in modulation of immune response of the host defense through target cell lysis and secretion of cytokines. Precise functions of NK cells are essential for the treatment outcome of different virus infections and malignant diseases. NK cells impart ...
    Quantitation of Regulatory Activity for the Complement Alternative Pathway Using an Adaptation of the AP50 in vitro Assay
    Authors:  Sheila Cabezas Falcon, David L Gordon and Jillian M Carr, date: 12/20/2018, view: 197, Q&A: 0
    [Abstract] Complement pathways function to identify and remove pathogens and infected cells. There are three complement pathways: the classical, lectin and alternative pathway (AP). While all pathways are activated following pathogen stimuli, the AP is constitutively active and tightly controlled by activators (e.g., Factor B, Factor D) and negative ...
    Method for Studying the Effect of Gene Silencing on Bacterial Infection-induced ERK1/2 Signaling in Bone-marrow Derived Macrophages
    Authors:  Gaurav Kumar, Subhash B. Arya and Amit Tuli, date: 12/20/2018, view: 446, Q&A: 0
    [Abstract] Macrophages are highly phagocytic cells that utilize various pathogen recognition receptors (PRRs) to recognize pathogen-associated molecular patterns (PAMPs). These PAMPs can be present within the microbe, such as bacterial CpG DNA, and are recognized by Toll-like receptor 9 (TLR9), a PRR present on the endosomal membrane of macrophages. PAMPs ...
    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 ...
    Integrin Dependent RhoB Activation Assay Using Leukocytes
    Authors:  Janne Lehtonen, Katarzyna Potrzebowska, Malin Samuelsson and Lena Svensson, date: 12/05/2018, view: 168, Q&A: 0
    [Abstract] To be able to migrate, leukocyte needs to re-use its adhesion molecules to move forward. These adhesion molecules are called integrins and are intracellularly transported via endocytosis and exocytosis in order to translocate to a new site on the cell membrane. The intracellular transportation is regulated by different small GTPases including ...
    Flow Cytometry Assay for Recycling of LFA-1 in T-lymphocytes
    Authors:  Katarzyna Potrzebowska, Janne Lehtonen, Malin Samuelsson and Lena Svensson, date: 12/05/2018, view: 291, Q&A: 0
    [Abstract] To enable cells to move forward, cell surface integrins are internalized into an endosomal compartment and subsequently intracellularly transported to be re-exposed at a new site on the cell membrane. Leukocytes are the fastest migrating cell type in the human body, which express the leukocyte-specific integrin LFA-1. Here, we describe a flow ...
    Use of Gas Chromatography to Quantify Short Chain Fatty Acids in the Serum, Colonic Luminal Content and Feces of Mice
    [Abstract] Short-Chain Fatty Acids (SCFAs) are a product of the fermentation of resistant starches and dietary fibers by the gut microbiota. The most important SCFA are acetate (C2), propionate (C3) and butyrate (C4). These metabolites are formed and absorbed in the colon and then transported through the hepatic vein to the liver. SCFAs are more concentrated ...
    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 ...
