    Characterization of Biological Motion Using Motion Sensing Superpixels
    [Abstract] Precise spatiotemporal regulation is the foundation for the healthy development and maintenance of living organisms. All cells must correctly execute their function in the right place at the right time. Cellular motion is thus an important dynamic readout of signaling in key disease-relevant molecular pathways. However despite the rapid ...
    A Refined Protocol for Identifying Citrulline-specific Monoclonal Antibodies from Single Human B Cells from Rheumatoid Arthritis Patient Material
    [Abstract] We describe here a detailed, refined protocol for the generation of citrulline-specific monoclonal antibodies from single human B cells from rheumatoid arthritis (RA) patients. This protocol provides a detailed guide of the procedure starting from single B cells of your choice and followed by amplification of the variable region of immunoglobulin ...
    In vitro Infection of Primary Human Monocytes with HIV-1
    Authors:  Patrick O’Connell, Yong-Hui Zheng, Andrea Amalfitano and Yasser A. Aldhamen, date: 07/05/2019, view: 838, Q&A: 0
    [Abstract] Monocyte infection by HIV-1 is an important component of chronic HIV pathogenesis. Following infection by HIV-1, monocytes are able to cross the blood brain barrier and set up a viral reservoir in the central nervous system. Additionally, in the setting of chronic HIV-1 infection, monocytes can become activated either directly through HIV-1 ...
    Measurement of CD74 N-terminal Fragment Accumulation in Cells Treated with SPPL2a Inhibitor
    Authors:  Rubén Martínez-Barricarte, Xiao-Fei Kong and Jean-Laurent Casanova, date: 06/05/2019, view: 837, Q&A: 0
    [Abstract] The recent discovery of human signal peptide peptidase-like 2a (SPPL2a) deficiency in humans revealed the toxicity associated with the accumulation of one of its substrates, CD74 N-terminal fragment (CD74-NTF), for certain type of dendritic cells (cDC2). We developed a two-step protocol for monitoring the accumulation of this molecule in different ...
    TZA, a Sensitive Reporter Cell-based Assay to Accurately and Rapidly Quantify Inducible, Replication-competent Latent HIV-1 from Resting CD4+ T Cells
    Authors:  Anwesha Sanyal, Vatsala S. Rangachar and Phalguni Gupta, date: 05/20/2019, view: 1722, Q&A: 1
    [Abstract] The latent HIV-1 viral reservoir in resting CD4+ (rCD4+) T cells represents a major barrier to an HIV-1 cure. There is an ongoing effort to identify therapeutic approaches that will eliminate or reduce the size of this reservoir. However, clinical investigators lack an assay to determine whether or not a decrease in the ...
    Assessment of Humoral Alloimmunity in Mixed Lymphocyte Reaction
    Authors:  Georgios Pissas and Theodoros Eleftheriadis, date: 01/20/2019, view: 2384, Q&A: 1
    [Abstract] Humoral alloimmunity remains a significant and unresolved problem that constrains allograft survival. Thus, there is a need for the development of an easy, preferably non-radioactive, and inexpensive protocol for assessing the effect of various drug treatments on humoral alloimmunity. In order to satisfy this demand, we developed such a protocol ...
    Monitoring Natural Killer Cell Function in Human Ovarian Cancer Cells of Ascitic Fluid
    Authors:  Vikash Kumar and Asok Mukhopadhyay, date: 12/20/2018, view: 1734, 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: 1414, Q&A: 2
    [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 ...
    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: 1495, 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 ...
    Platelet Migration and Bacterial Trapping Assay under Flow
    Authors:  Shuxia Fan, Michael Lorenz, Steffen Massberg and Florian Gaertner, date: 09/20/2018, view: 2241, Q&A: 0
    [Abstract] Blood platelets are critical for hemostasis and thrombosis, but also play diverse roles during immune responses. We have recently reported that platelets migrate at sites of infection in vitro and in vivo. Importantly, platelets use their ability to migrate to collect and bundle fibrin (ogen)-bound bacteria accomplishing ...
