Dissection and Immunohistochemistry of Larval, Pupal and Adult Drosophila Retinas


JoVE 4347 11/14/2012

Department of Biology, New York University

The Drosophila retina is a crystal-like lattice composed of a small number of cell types that are generated in a stereotyped manner 1. Its amenability to sophisticated genetic analysis allows the study of complex developmental programs. This protocol describes dissections and immunohistochemistry of retinas at three discrete developmental stages, with a focus on photoreceptor differentiation.

Skin Tattooing As A Novel Approach For DNA Vaccine Delivery


JoVE 50032 10/18/2012

1Department of Biochemistry and Molecular Pharmacology, New York University School of Medicine, 2Department of Pathology, New York University School of Medicine, 3Healthcare System, Veterans Affairs New York Harbor

Skin tattooing is a potent and safe way to delivery DNA vaccine intradermally. Here, a DNA plasmid encoding EGFP is delivered by tattooing to the skin of a laboratory mouse, and the expression of EGFP in the skin cells is then inspected by confocal microscopy.

Extinction Training During the Reconsolidation Window Prevents Recovery of Fear


JoVE 3893 8/24/2012

1Departments of Psychiatry and Neuroscience, and Friedman Brain Institute, Mt. Sinai School of Medicine, 2Department of Psychology, New York University, 3Department of Psychology and Center for Neural Science, New York University

Conditioned fear can be diminished through an inhibitory process called extinction, but can resurface under conditions such as the passage of time or exposure to stress. Our protocol presents a novel way of preventing fear recovery by introducing extinction during the reconsolidation window (the re-storage phase of a reactivated memory).

Isolation and Culture of Human Fungiform Taste Papillae Cells


JoVE 3730 5/17/2012

1Monell Chemical Senses Center, 2New York University College of Dentistry, 3AFB International

We aimed to develop a reproducible protocol for isolating and maintaining long-term cultures of human fungiform taste papillae cells. Cells from human fungiform papillae obtained by biopsy were successfully maintained in culture for more than eight passages (12 months) without loss of viability.

The protocol describes an efficient and reproducible model system to study herpes simplex virus type 1 (HSV-1) latency and reactivation. The assay employs homogenous sympathetic neuron cultures and allows for the molecular dissection of virus-neuron interactions using a variety of tools including RNA interference and expression of recombinant proteins.

Imaging of HIV-1 Envelope-induced Virological Synapse and Signaling on Synthetic Lipid Bilayers


JoVE 3757 3/08/2012

1Department of Pathology, New York University Langone School of Medicine, 2Program in Molecular Pathogenesis, Marty and Helen Kimmel Center for Biology and Medicine and Skirball Institute for Biomolecular Medicine, 3Laboratory of Molecular Immunogenetics, National Institute of Arthritis and Musculoskeletal and Skin Diseases, National Institutes of Health, 4Veteran Affairs New York Harbor Healthcare System

This article describes a method to visualize formation of an HIV-1 envelope-induced virological synapse on glass supported planar bilayers by total internal reflection fluorescence (TIRF) microscopy. The method can also be combined with immunofluorescence staining to detect activation and redistribution of signaling molecules that occur during HIV-1 envelope-induced virological synapse formation.

Modified Yeast-Two-Hybrid System to Identify Proteins Interacting with the Growth Factor Progranulin


JoVE 3562 1/17/2012

1Department of Orthopaedic Surgery, NYU Hospital for Joint Diseases, 2Department of Cell Biology, New York University School of Medicine

We have modified the conventional yeast two-hybrid screening, an effective genetic tool in identifying protein interaction. This modification markedly shortens the process, reduces the workload, and most importantly, reduces the number of false positives. In addition, this approach is reproducible and reliable.

How to Create and Use Binocular Rivalry


JoVE 2030 11/10/2010

1Department of Psychology, New York University, 2Centre for Neural Science, New York University, 3Department of Psychology, Princeton University, 4Neuroscience Institute, Princeton University

Binocular rivalry occurs when the eyes are presented with different images at the same location: one image dominates while the other is suppressed, and dominance alternates periodically. Rivalry is useful for investigating perceptual selection and visual awareness. Here we describe several easy methods for creating and using binocular rivalry stimuli.

Technique to Collect Fungiform (Taste) Papillae from Human Tongue


JoVE 2201 9/18/2010

1Department of Basic Science and Craniofacial Biology, College of Dentistry, New York University, 2Department of Internal Medicine and Department of Psychiatry, School of Medicine, Washington University in St. Louis, 3Veterans Affairs Medical Center, 4School of Dental Medicine, Department of Biochemistry, University of Pennsylvania-School of Medicine, 5 , Monell Chemical Senses Center, 6Monell Chemical Senses Center

Knowledge of molecular mechanisms underlying gustatory transduction has recently enjoyed significant advances, largely due to using animal models. However, the wide diversity in taste sensitivity and specificity among mammals warrants studies in human tissue. We describe a biopsy technique to collect living taste cells from the papillae on human tongue.

Assessment of Immunologically Relevant Dynamic Tertiary Structural Features of the HIV-1 V3 Loop Crown R2 Sequence by ab initio Folding


JoVE 2118 9/15/2010

Department of Pharmacology, School of Medicine, New York University

The crown region of different V3 loop sequences of the surface envelope glycoprotein (gp120) of HIV-1 can be structurally characterized in many cases by in silico folding of positions 10 to 22 of the loop using a state-of-the-art ab initio folding algorithm. Here we demonstrate the folding and evaluation of this region of the V3 loop from the R2 strain of HIV-1, a uniquely neutralization sensitive strain with puzzling functional properties.

Center for Genomics and Systems Biology, Department of Biology, New York University

A method for isolating specific cell types from plant material is demonstrated. This technique employs transgenic marker lines expressing fluorescent proteins in particular cell types, cellular dissociation and Fluorescence Activated Cell Sorting. Additionally, a growth setup is established here that facilitates treatment of Arabidopsis thaliana seedlings prior to cell sorting.

Supported Planar Bilayers for the Formation of Study of Immunological Synapses and Kinapse


JoVE 947 9/15/2008

Helen and Martin S. Kimmel Center for Biology and Medicine at the Skirball Institute of Biomolecular, New York University - NYU

Supported planar bilayers are powerful tools that can be used to model the molecular interactions in an immunological synapse. Here, we show methods for anchoring cell adhesion proteins known to modulate synapse formation to the upper leaflet of the lipid bilyer and visualize synapse formation using TIRF microscopy.
