JoVE Immunology and Infection
JoVE Immunology and Infection includes content from a variety of fields working toward a shared initiative of improving global health. Techniques evaluating the biological response to pathogens from the molecular to organismal level are presented as well as therapeutic agents and their efficacy in treating disease.

Generation of Lymphocytic Microparticles and Detection of their Proapoptotic Effect on Airway Epithelial Cells

1Departments of Pediatrics and Pharmacology, University of Montréal, 2Department of Pulmonology, Chongqing Southwest Hospital, Third Military Medical University


JoVE 52651

Cell membrane–shed microparticles (MPs) are active biological vesicles that can be isolated and their pathophysiological effects investigated in various models. Here we describe a method for generating MPs derived from T lymphocytes (LMPs) and for demonstrating their proapoptotic effect on airway epithelial cells.

Loop-mediated Isothermal Amplification (LAMP) Assays for the Species-specific Detection of Eimeria that Infect Chickens

1Department of Pathology and Pathogen Biology, Royal Veterinary College, London, 2BIOPHARM, Research Institute of Biopharmacy and Veterinary Drugs


JoVE 52552

Diagnosis of Eimeria infection in chickens remains demanding. Parasite morphology- and host pathology-led approaches are commonly inconclusive, while molecular approaches based on PCR have proven demanding in cost and expertise. The aim of this protocol is to establish loop-mediated isothermal amplification (LAMP) as a straightforward molecular diagnostic for eimerian infection.

Generation of CAR T Cells for Adoptive Therapy in the Context of Glioblastoma Standard of Care

1Duke Brain Tumor Immunotherapy Program, Department of Neurosurgery, Duke University, 2Department of Biomedical Engineering, Duke University, 3Department of Pathology, Duke University


JoVE 52397

The lymphodepletive and immunomodulatory effects of chemotherapy and radiation standard of care can be leveraged to enhance the antitumor efficacy of T cell immunotherapy. We outline a method for generating EGFRvIII-specific chimeric antigen receptor (CAR) T cells and administering them in the context of glioblastoma standard of care.

Super-resolution Imaging of the Natural Killer Cell Immunological Synapse on a Glass-supported Planar Lipid Bilayer

1Center for Human Immunobiology, Texas Children's Hospital, 2Department of Pediatrics, Baylor College of Medicine, 3Department of Pathology and Immunology, Baylor College of Medicine


JoVE 52502

We describe here a combination of the glass-supported lipid bilayer technique of forming immunological synapses with the super-resolution imaging technique of stimulated emission depletion (STED) microscopy. The goal of this protocol is to provide users with the instructions necessary to successfully carry out these two techniques.

Radial Mobility and Cytotoxic Function of Retroviral Replicating Vector Transduced, Non-adherent Alloresponsive T Lymphocytes

1Department of Neurosurgery, UCLA David Geffen School of Medicine, 2Department of Molecular and Medical Pharmacology, UCLA David Geffen School of Medicine, 3Department of Medicine, UCLA David Geffen School of Medicine, 4Brain Research Institute, UCLA David Geffen School of Medicine, 5Jonsson Comprehensive Cancer Center, UCLA David Geffen School of Medicine


JoVE 52416

We describe a protocol to monitor radial mobility of non-adherent immune cells in vitro using a cell sedimentation manifold/slide apparatus. Cell migration is tracked on monolayers of tumor cells or on extracellular matrix proteins. Examination by light and fluorescence microscopy allows for observation of cell mobility and cytotoxic functionality.

An Ex vivo Model of an Oligodendrocyte-directed T-Cell Attack in Acute Brain Slices

1Department of Neurology, University of Münster, 2Germany and Interdisciplinary Center for Clinical Research (IZKF) Münster, 3Institute of Physiology I - Neuropathophysiology I, University of Münster


JoVE 52205

To address mechanisms of demyelination and neuronal apoptosis in cortical lesions of inflammatory demyelinating disorders, different animal models are used. We here describe an ex vivo approach by using oligodendrocyte-specific CD8+ T-cells on brain slices, resulting in oligodendroglial and neuronal death. Potential applications and limitations of the model are discussed.

Investigating Mast Cell Secretory Granules; from Biosynthesis to Exocytosis

1Department of Cell and Developmental Biology, Sackler Faculty of Medicine, Tel Aviv University, 2Division of Allergy and Immunology, Department of Pediatrics, Cincinnati Children's Hospital Medical Center, University of Cincinnati College of Medicine, 3Laboratory of Membrane Trafficking Mechanisms, Department of Developmental Biology and Neurosciences, Graduate School of Life Sciences, Tohoku University


JoVE 52505

The goal of the present protocol was to develop a method that will allow functional genomic analyses of mast cell secretion. The protocol is based on quantitative assessment of the release of a fluorescent reporter gene cotrasfected with the gene of interest and real time analyses of the secretory granule's morphology.

Nucleocapsid Annealing-Mediated Electrophoresis (NAME) Assay Allows the Rapid Identification of HIV-1 Nucleocapsid Inhibitors

1Department of Pharmaceutical and Pharmacological Sciences, University of Padova, 2The RNA Institute, SUNY Albany


JoVE 52474

This protocol describes NAME, an assay that allows the rapid identification of molecules able to inhibit in vitro the chaperone activities of HIV-1 nucleocapsid protein.

Electroporation of Functional Bacterial Effectors into Mammalian Cells

1Biological Sciences Division, Pacific Northwest National Laboratory, 2Environmental Molecular Science Laboratory, Pacific Northwest National Laboratory, 3Structural Proteomics Group, Ontario Center for Structural Proteomics, University of Toronto, 4Center for Bioproducts and Bioenergy, Washington State University


JoVE 52296

Electroporation was used to insert purified bacterial virulence effector proteins directly into living eukaryotic cells. Protein localization was monitored by confocal immunofluorescence microscopy. This method allows for studies on trafficking, function, and protein-protein interactions using active exogenous proteins, avoiding the need for heterologous expression in eukaryotic cells.

Scalable High Throughput Selection From Phage-displayed Synthetic Antibody Libraries

1The Recombinant Antibody Network, 2The Banting and Best Department of Medical Research, University of Toronto, 3Antibiome Center, University of California, San Francisco at Mission Bay, 4Department of Biochemistry and Molecular Biology, The University of Chicago


JoVE 51492

A method is described with visual accompaniment for conducting scalable, high throughput selections from phage-displayed combinatorial synthetic antibody libraries against hundreds of antigens simultaneously. Using this parallel approach, we have isolated antibody fragments that exhibit high affinity and specificity for diverse antigens that are functional in standard immunoassays.
