Intra-lymph Node Injection of Biodegradable Polymer Particles

1Fischell Department of Bioengineering, University of Maryland, College Park


JoVE 50984

Lymph nodes are the immunological tissues that orchestrate immune response and are a critical target for vaccines. Biomaterials have been employed to better target lymph nodes and to control delivery of antigens or adjuvants. This paper describes a technique combining these ideas to inject biocompatible polymer particles into lymph nodes.

Models and Methods to Evaluate Transport of Drug Delivery Systems Across Cellular Barriers

1Fischell Department of Bioengineering, University of Maryland, 2Institute for Bioscience and Biotechnology Research, University of Maryland


JoVE 50638

Many therapeutic applications require safe and efficient transport of drug carriers and their cargoes across cellular barriers in the body. This article describes an adaptation of established methods to evaluate the rate and mechanism of transport of drug nanocarriers (NCs) across cellular barriers, such as the gastrointestinal (GI) epithelium.

Live Imaging Assay for Assessing the Roles of Ca2+ and Sphingomyelinase in the Repair of Pore-forming Toxin Wounds

1Department of Cell Biology and Molecular Genetics, University of Maryland


JoVE 50531

Live imaging of cells exposed to the lipophilic dye FM1-43 allows precise determination of the kinetics by which pore-forming toxins are removed from the plasma membrane. This is a sensitive assay that can be used to assess requirements for Ca2+, sphingomyelinase and other factors on plasma membrane repair.

Artificial Antigen Presenting Cell (aAPC) Mediated Activation and Expansion of Natural Killer T Cells

1Department of Microbiology and Immunology, University of Maryland


JoVE 4333

Here we describe a method for activating and expanding human NKT cells from bulk T cell populations using artificial antigen presenting cells (aAPC). The use of CD1d-based aAPC provides a standardized method for generating high numbers of functional NKT cells.

A New Screening Method for the Directed Evolution of Thermostable Bacteriolytic Enzymes

1Institute for Bioscience and Biotechnology Research, University of Maryland


JoVE 4216

A novel directed evolution method specific to the field of thermostability engineering was developed and consequently validated for bacteriolytic enzymes. After only one round of random mutagenesis, an evolved bacteriolytic enzyme, PlyC 29C3, displayed greater than twice the residual activity when compared to the wild-type protein after elevated temperature incubation.

Moser Research Institute at Kennedy Krieger, Johns Hopkins University, 2Department of Neurology, Johns Hopkins School of Medicine, 3University of Maryland, 4Experimental Neurology, Biogen Idec, 5The Brain Science Institute, Johns Hopkins School of Medicine, 6Department of Pediatrics, Johns Hopkins School of Medicine


JoVE 3462

This protocol outlines the derivation of Glial Restricted Precursors from fetal spinal cords and maintained in vitro either for transplantation or for the study of oligodendrocytic lineage.

Bridging the Bio-Electronic Interface with Biofabrication

1Fischell Department of Bioengineering, University of Maryland, 2Institute for Bioscience and Biotechnology Research, University of Maryland, 3Department of Materials Science and Engineering, University of Maryland


JoVE 4231

This article describes a biofabrication approach: deposition of stimuli-responsive polysaccharides in the presence of biased electrodes to create biocompatible films which can be functionalized with cells or proteins. We demonstrate a bench-top strategy for the generation of the films as well as their basic uses for creating interactive biofunctionalized surfaces for lab-on-a-chip applications.

The Mouse Forced Swim Test

1Department of Psychiatry, University of Maryland School of Medicine, 2Tulane University School of Medicine, 3Department of Pharmacology and Experimental Therapeutics, University of Maryland School of Medicine, 4The Program in Neuroscience, University of Maryland


JoVE 3638

The forced swim test is validated as an experimental approach to assess potential antidepressant efficacy in rodents. Experimental animals are placed in a tank of water and escape-related mobility behavior is quantified. The common procedures for the mouse version of this test are described.

JoVE 3769

The tail-suspension test is validated as an experimental procedure to assess antidepressant efficacy of drug treatments in mice. Mice are suspended by their tails for six minutes and escape-related behaviors are assessed. We describe procedures used in conducting the tail suspension test.

Chromatographic Purification of Highly Active Yeast Ribosomes

1Department of Cell Biology and Molecular Genetics, University of Maryland, 2Department of Biotechnology and Microbiology, Vilnius University


JoVE 3214

Contamination of preparations of eukaryotic ribosomes purified by traditional methods by co-purifying nucleases and proteases negatively impacts on downstream biochemical and structural analyses. A rapid and simple chromatographic purification method is used to solve this problem using yeast ribosomes as a model system.

Physiological, Morphological and Neurochemical Characterization of Neurons Modulated by Movement

1Department of Neural and Pain Sciences, University of Maryland


JoVE 2650

A technique is described to quantify the in vivo physiological response of mammalian neurons during movement and correlate the physiology of the neuron with neuronal morphology, neurochemical phenotype and synaptic microcircuitry.

Methods for Rapid Transfer and Localization of Lyme Disease Pathogens Within the Tick Gut

1Department of Veterinary Medicine, University of Maryland, 2Department of Entomology, Connecticut Agricultural Experiment Station


JoVE 2544

Lyme disease research studies often require generation of ticks infected with the pathogen Borrelia burgdorferi, a process that typically takes several weeks. Here we demonstrate a microinjection-based tick infection procedure that can be accomplished within hours. We also demonstrate an immunofluorescence method for in situ localization of B. burgdorferi within ticks.

Gross and Fine Dissection of Inner Ear Sensory Epithelia in Adult Zebrafish (Danio rerio)

1Genome Technology Branch, National Human Genome Research Institute, 2Neuroscience and Cognitive Science Program, University of Maryland


JoVE 1211

The inner ear sensory epithelium of adult zebrafish is a good model system for understanding the mechanisms of hair cell regeneration in adult vertebrates. This protocol demonstrates the fine dissection of the epithelia, through which we can get tissue samples for studying the regenerative events at cellular and subcellular levels.
