Hepatitis B virus (HBV) chronically infects over 300 million people worldwide. Many of them will die of chronic hepatitis or hepatocellular carcinoma. The present technology relates to the isolation and characterization of a novel neutralizing chimpanzee monoclonal antibody to HBV. The antibody was identified through a combinatorial antibody library constructed from bone marrow cells of a chimpanzee experimentally infected with HBV. The selected monoclonal antibody has been shown to react equally well with wild-type HBV and the most common neutralization escape mutant variants.

This application describes a composition and method for treating inflammatory bowel disease or other autoimmune diseases. The composition utilizes a vector which contains a first promoter which controls the expression of a regulatory transcription factor and a second inducible promoter which controls the expression of the gene of interest. The preferred gene of interest encodes an isoform of TGF-beta such as TGF-beta₁ or TGF-beta₃. The isoform of TGF-beta does not have to be hTGF-beta and can be a latent or active isoform of TGF-beta.

The invention provides a method of diagnosing X-linked severe combined immunodeficiency (XSCID) in males or determining whether females are carriers. This method is based upon the presence of either a mutated or truncated IL-2Rgamma gene. The invention also discloses a method of treating XSCID as well as a method for monitoring the therapy.

The complexity of taste discrimination (salty, sour, sweet, umami and bitter) varies between human individuals and populations. Sweet and umami (the taste of glutamate) tastes play a major role in the perception of calorically-rich and essential nutrients and there are well-documented differences in individual perception of sweet and umami flavorings, many of which appear to be genetic in origin.

Transformation-Associated Recombination (TAR) cloning in yeast is a unique method for selective isolation of large chromosomal fragments or entire genes from complex genomes without the time-consuming step of library construction.¹ The technique involves homologous recombination during yeast spheroplast transformation between genomic DNA and a TAR vector that has short (approximately 60bp) 5’ and 3’ gene targeting sequences (hooks).

Cytokines exert their respective biochemical and physiological effects by binding to specific receptor molecules, which then stimulate signal transduction pathways. Interleukin-21 (IL-21) is a type I cytokine whose receptor is expressed on T, B, and NK cells.

The hybridoma producing a monoclonal antibody against the major flagellin protein (FlaB) is available for licensing. This antibody can be used in diagnostic and research applications related to Lyme disease or other Borrelia-caused conditions. More information about this antibody can be found in Barbour et al., Infection and Immunity, May 1986, volume 52(5), pages 549-554.

A primary goal of diabetes therapy is to improve control of blood glucose levels (known as glycemic control) in patients. Prospective studies of both Type 1 and Type 2 diabetes indicate that careful glycemic control significantly reduces the risk of microvascular, neurological, and cardiovascular complications of diabetes. The current method of monitoring glycemic control involves measuring levels of the intracellular hemoglobin (HbA1C).

Available for licensing and commercial development are novel biotechnological tools, prophylactics, therapeutics, and methods for modulating the activation state of an antigen presenting cell (APC) and thereby modulating the activation of a killer T cell.

Available for licensing and commercial development is a newly discovered bacterium in the Acetobacteraceae family. This bacterium was isolated, characterized and grown from lymph nodes of a patient with chronic granulomatous disease (CGD), a rare genetic disorder that impairs the immune system.
