A Simple Protocol for Platelet-mediated Clumping of Plasmodium falciparum-infected Erythrocytes in a Resource Poor Setting
1Malawi-Liverpool-Wellcome Trust Clinical Research Programme, 2Liverpool School of Tropical Medicine, 3Department of Microbiology, Division of Medical Parasitology, New York University School of Medicine
This method investigates the platelet-mediated clumping phenotype of Plasmodium falciparum-infected erythrocytes (pRBC) in clinical isolates. This is performed by isolating and co-incubating platelet-rich plasma and a suspension of pRBC.

Accelerated Type 1 Diabetes Induction in Mice by Adoptive Transfer of Diabetogenic CD4+ T Cells
Department of Microbiology & Immunology, Pennsylvania State University College of Medicine
We provide a reproducible method to induce type 1 diabetes (T1D) in mice within two weeks by the adoptive transfer of islet antigen-specific, primary CD4+ T cells.

Oral Transmission of Listeria monocytogenes in Mice via Ingestion of Contaminated Food
Department of Microbiology, Immunology, and Molecular Genetics, University of Kentucky
This paper describes a novel method for oral infection of mice using Listeria monocytogenes-contaminated food. The protocol can readily be adapted for use with other food borne bacterial pathogens.

Trans-vivo Delayed Type Hypersensitivity Assay for Antigen Specific Regulation
Department of Surgery, University of Wisconsin-Madison, School of Medicine and Public Health
We describe a valuable diagnostic assay that could potentially be used to decide the withdrawal of immunosuppression after transplant without elevated risk of graft rejection. The assay uses the principles of Delayed Type Hypersensitivity and provides accurate assessment of both donor specific effector and regulatory immune responses mounted by recipients.

Isolation of Precursor B-cell Subsets from Umbilical Cord Blood
1Department of Pathology and Anatomical Sciences, University of Missouri-Columbia, 2Laboratory for Infectious Disease Research, University of Missouri-Columbia
Here we describe a protocol for isolating subsets of precursor B-cells from umbilical cord blood. A sufficient quantity and quality of nucleic acids may be extracted from the cells and used in subsequent assays utilizing DNA or RNA.

Mass Spectrometric Analysis of Glycosphingolipid Antigens
1Undergraduate Program, Rice University, 2Proteomics Facility, Department of Pathology, University of Texas MD Anderson Cancer Center, 3Department of Melanoma Medical Oncology, University of Texas MD Anderson Cancer Center, 4University of Texas Graduate School of Biological Sciences at Houston
A specific and sensitive method to gain insight into the expression profile of glycosphingolipid antigens in immune organs and cells is described. The method takes advantage of the ion trap mass spectrometry allowing step-wise fragmentation of glycosphingolipid molecules for structural analysis in comparison to chemically synthesized standards.

A Simple and Efficient Method to Detect Nuclear Factor Activation in Human Neutrophils by Flow Cytometry
1Department of Biological Sciences, University of Alberta, 2División de Estudios de Posgrado e Investigación, Facultad de Odontología, Universidad Nacional Autónoma de México, 3Department of Immunology, Instituto de Investigaciones Biomédicas, Universidad Nacional Autónoma de México
Neutrophils are the most abundant leukocytes in blood. Neutrophils possess transcriptionally regulated functions such as production of proinflammatory cytokines and inhibition of apoptosis. These functions can be studied with the method presented here, which allows detection and quantification of nuclear factors by flow cytometry in isolated nuclei

PRP as a New Approach to Prevent Infection: Preparation and In vitro Antimicrobial Properties of PRP
1Department of Orthopaedics, School of Medicine, West Virginia University, 2Department of Orthopaedics, Stem Cell Research Center, University of Pittsburgh, 3WVNano Initiative, 4Mary Babb Randolph Cancer Center
Implant-associated infection is a significant clinical complication. This study describes an approach using platelet-rich plasma (PRP) to prevent implant-associated infections, presents the protocol for preparing PRP with constant platelet concentration, and reports the newly identified antimicrobial properties of PRP and related protocols for examining such antimicrobial properties in vitro.

Real-time Imaging of Heterotypic Platelet-neutrophil Interactions on the Activated Endothelium During Vascular Inflammation and Thrombus Formation in Live Mice
1Department of Pharmacology, University of Illinois at Chicago, 2Department of Anesthesiology, University of Illinois at Chicago
Here we report an experimental technique of fluorescence intravital microscopy to visualize heterotypic platelet-neutrophil interactions on the activated endothelium during vascular inflammation and thrombus formation in live mice. This microscopic technology will be valuable to study the molecular mechanism of vascular disease and to test pharmacologic agents under pathophysiological conditions.

Tractable Mammalian Cell Infections with Protozoan-primed Bacteria
Department of Molecular Microbiology & Immunology, Oregon Health & Science University
This technique provides a method to harvest, normalize and quantify intracellular growth of bacterial pathogens that are pre-cultivated in natural protozoan host cells prior to infections of mammalian cells. This method can be modified to accommodate a wide variety of host cells for the priming stage as well as target cell types.
