Induction and Monitoring of Adoptive Delayed-Type Hypersensitivity in Rats
Department of Physiology and Biophysics, University of California, Irvine (UCI)
Delayed type hypersensitivity (DTH) is an inflammatory reaction mediated by CCR7- effector memory T (TEM) lymphocytes. Here we demonstrate how to activate antigen-specific TEM cells, induce adoptive DTH in Lewis rats and monitor the inflammatory response.

Analysis of Pulmonary Dendritic Cell Maturation and Migration during Allergic Airway Inflammation
1Stem Cell and Cancer Research Institute, McMaster University, Hamilton, 2Physiology and Experimental Medicine Research Program, Hospital for Sick Children, University of Toronto
We describe a strategy to monitor maturation and migration of pulmonary dendritic cells in response to ovalbumin in the setting of ovalbumin induced allergic airway inflammation. This strategy can be modified to assess migration of pulmonary dendritic cells in settings of infection.

The Use of Carboxyfluorescein Diacetate Succinimidyl Ester (CFSE) to Monitor Lymphocyte Proliferation
Department of Immunology, John Curtin School of Medical Research, Australian National University
CFSE covalently labels long-lived intracellular molecules with the fluorescent dye, carboxyfluorescein. As such, when a CFSE-labeled cell divides, its progeny have half the amount of fluorescence, which can thereby be used to assess cell division. This article describes the procedures typically used for labeling mouse lymphocytes with CFSE.

Induction and Monitoring of Active Delayed Type Hypersensitivity (DTH) in Rats
Department of Physiology and Biophysics, University of California, Irvine (UCI)
Delayed type hypersensitivity (DTH) is an inflammatory reaction mediated by CCR7- effector memory T lymphocytes. Here we demonstrate how to induce active DTH in Lewis rats and monitor the inflammatory response.

A Reversible, Non-invasive Method for Airway Resistance Measurements and Bronchoalveolar Lavage Fluid Sampling in Mice
1Department of Medicine, Baylor College of Medicine (BCM), 2Millenium Premier Group, 3Department of Immunology, Baylor College of Medicine (BCM)
Repeated measurements of rodent respiratory physiology and sampling of airway inflammatory cells are desirable, but generally not feasible. Here we describe a repeatable method for orally intubating mice that permits repeated measurements of airway hyperreactivity and sampling of airway inflammatory cells.

Monitoring Dendritic Cell Migration using 19F / 1H Magnetic Resonance Imaging
1Experimental and Clinical Research Center, A joint cooperation between the Charité Medical Faculty and the Max Delbrück Center for Molecular Medicine, 2Berlin Ultrahigh Field Facility (B.U.F.F.), Max Delbrück Center for Molecular Medicine
Tracking of cells using MRI has gained remarkable attention in the past years. This protocol describes the labeling of dendritic cells with fluorine (19F)-rich particles, the in vivo application of these cells, and monitoring the extent of their migration to the draining lymph node with 19F/1H MRI and 19F MRS.

Lipid Vesicle-mediated Affinity Chromatography using Magnetic Activated Cell Sorting (LIMACS): a Novel Method to Analyze Protein-lipid Interaction
Institute of Molecular Medicine and Genetics, Georgia Health Sciences University
To test the interaction of a protein with its target lipid we used MACS and Annexin V-conjugated magnetic beads and lipid vesicles synthesized from the target lipid and Annexin V-binding phosphatidylserine. Proteins bound to the target lipid are co-purified and analyzed after elution from the beads.

Murine Model of Allergen Induced Asthma
Experimental mouse models of allergic asthma offer new possibilities for studying disease pathogenesis and developing new therapeutics. These models are well suited to measuring factors governing the allergic immune response, airway inflammation, and pulmonary pathophysiology.

Imaging Effector Memory T cells in the Ear After Induction of Adoptive DTH
1Department of Physiology and Biophysics, University of California, Irvine (UCI), 2Department of Neurobiology and Behavior, University of California, Irvine (UCI)
Here we demonstrate a method for inducing and recording the progress of a delayed type-hypersensitivity (DTH) reaction in the rat ear. This is followed by a demonstration of the preparation of rat ear tissue for two-photon imaging of the effector / memory T cell response.

Generation of Bone Marrow Derived Murine Dendritic Cells for Use in 2-photon Imaging
1Department of Physiology and Biophysics, University of California, Irvine (UCI), 2Department of Neurobiology and Behaviour, University of California, Irvine (UCI)
Antigen presentation in secondary lymphoid organs by dendritic cells is crucial for the initiation of the T cell mediated adaptive immune response. Here we demonstrate the culture of bone marrow derived murine dendritic cells, activation, and labeling for 2-photon imaging.

Fast and Sensitive Colloidal Coomassie G-250 Staining for Proteins in Polyacrylamide Gels
Biological Medical Research Center (BMFZ), University Duesseldorf
This video shall popularize a colloidal Coomassie G-250 staining protocol according to Kang et al. for the detection of average 4 ng protein in gels. The staining is completed within 2 hours and without any effort. We routinely use Kang's protocol for analytical purposes in gel-based proteomics.

Bilaminar Co-culture of Primary Rat Cortical Neurons and Glia
Department of Pharmacology and Physiology, Drexel University College of Medicine
Here we provide a protocol for culturing rat cortical neurons in the presence of a glial feeder layer. The cultured neurons establish polarity and create synapses, and can be separated from the glia for use in various applications, such as electrophysiology, calcium imaging, cell survival assays, immunocytochemistry, and RNA/DNA/protein isolation.

Overcoming Unresponsiveness in Experimental Autoimmune Encephalomyelitis (EAE) Resistant Mouse Strains by Adoptive Transfer and Antigenic Challenge
1Department of Medicine, Section of Cardiology, St. John-Providence Health System, 2Department of Immunology and Microbiology, Wayne State University School of Medicine
Certain mouse strains are able to resist induction of experimental autoimmune encephalomyelitis (EAE) with myelin basic protein. Described here is a simple immunization protocol that reverses the unresponsiveness and induces paralytic disease in several typical EAE resistant mouse stains.

In vitro Measurements of Tracheal Constriction Using Mice
Department of Physiology, UT Health Science Center, San Antonio
Transgenic mice have been extremely useful in ascribing physiological function to genes. As such, research in general, and functional studies of airway, in particular, have undergone a remarkable shift toward murine models. Here we provide protocols for in vitro trachea constriction studies to evaluate smooth muscle function in murine airway.
