    Co-immunostaining of ICAM-1, ICAM-2, and CD31 in Mouse Kidney Glomeruli
    Author:  Sun-sang J. Sung, date: 07/05/2020, view: 678, 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 ...
    Modeling NOTCH1 driven T-cell Acute Lymphoblastic Leukemia in Mice
    Authors:  Agnieszka A. Wendorff and Adolfo A. Ferrando, date: 05/20/2020, view: 1225, Q&A: 0
    [Abstract] T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological malignancy that arises from transformation of T-cell primed hematopoietic progenitors. Although T-ALL is a heterogenous and molecularly complex disease, more than 65% of T-ALL patients carry activating mutations in the NOTCH1 gene. The majority of T-ALL–associated ...
    Assessing in vitro and in vivo Trogocytosis By Murine CD4+ T cells
    Authors:  Jim Reed and Scott A. Wetzel, date: 05/05/2020, view: 1021, Q&A: 0
    [Abstract] Recognition of antigens by lymphocytes (B, T, and NK) on the surface of an antigen-presenting cell (APC) leads to lymphocyte activation and the formation of an immunological synapse between the lymphocyte and the APC. At the immunological synapse APC membrane and associated membrane proteins can be transferred to the lymphocyte in a process called ...
    Bacterial Synchronized Transfer Assays in Bone Marrow Derived Macrophages
    Authors:  Sedelia R Dominguez, Tom Kawula and Shaun P Steele, date: 11/20/2019, view: 1685, Q&A: 0
    [Abstract] Merocytophagy (“mero”, Greek for partial; “cytophagy” for cell eating) is a process by which cells acquire microbes and cytosolic material through phagocytosis of a small portion of neighboring cells upon cell-cell contact. Cell-cell contact dependent transfer events can be assessed through co-incubation of differently labeled cells. With these ...
    Isolation of Neutrophil Nuclei for Use in NETosis Assays
    Author:  Dave Boucher, date: 09/05/2019, view: 2029, Q&A: 0
    [Abstract] Neutrophils are critical immune cells that protect our body against invading pathogens. They generate antibacterial DNA structures called neutrophil extracellular traps (NET). Recently we identified a new mechanism that enables NET formation. We observed that following recognition of lipopolysaccharides, inflammatory caspases cleave Gasdermin D ...
    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: 3818, 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 ...
    Measurement of TLR4 and CD14 Receptor Endocytosis Using Flow Cytometry
    Authors:  Michael S. Schappe and Bimal N. Desai, date: 07/20/2018, view: 5367, Q&A: 0
    [Abstract] After recognizing extracellular bacterial lipopolysaccharide (LPS), the toll-like receptor 4 (TLR4)-CD14 signaling complex initiates two distinct signaling pathways–one from the plasma membrane and the other from the signaling endosomes (Kagan et al., 2008). Understanding the early stages of TLR4 signal transduction therefore requires a ...
    Quantification of Extracellular Double-stranded RNA Uptake and Subcellular Localization Using Flow Cytometry and Confocal Microscopy
    Authors:  Tan A Nguyen, Lachlan Whitehead and Ken C Pang, date: 06/20/2018, view: 3621, Q&A: 0
    [Abstract] Double-stranded RNA is a potent pathogen-associated molecular pattern (PAMP) produced as a by-product of viral replication and a well-known hallmark of viral infection. Viral dsRNAs can be released from infected cells into the extracellular space and internalized by neighboring cells via endocytosis. Mammals possess multiple pattern recognition ...
    Visualization of RNA at the Single Cell Level by Fluorescent in situ Hybridization Coupled to Flow Cytometry
    Authors:  Alice Coillard and Elodie Segura, date: 06/20/2018, view: 3974, Q&A: 0
    [Abstract] The protocol described here has been developed to detect RNA at the single cell level. Fluorescent probes hybridize to target RNAs and are detected by flow cytometry after multiple amplification steps. Different types of RNA can be detected such as mRNA, long noncoding RNA, viral RNA or telomere RNA and up to 4 different target probes can be used ...
    Ectopic Gene Expression in Macrophages Using in vitro Transcribed mRNA
    Authors:  Pallavi Chandra and Jennifer A. Philips, date: 05/20/2018, view: 3986, Q&A: 0
    [Abstract] Macrophages are immune cells that contribute to host defense through various mechanisms including phagocytosis and antigen presentation. Their antimicrobial capacity is subverted by clinically important intracellular pathogens such as Mycobacterium tuberculosis. The study of host-pathogen interactions using these cells is therefore of ...
