Chimeric Antibodies Against Hepatitis B e-Antigen

The invention relates to recombinant chimeric rabbit/human monoclonal antibody fragments (Fabs) against hepatitis B Virus e-antigen (HBeAg), notably Fab me6. Viral hepatitis is the seventh leading cause of death worldwide. Hepatitis B core antigen (HBcAg) forms an icosahedral structure containing the viral genome. Both the HBcAg and the HBeAg of interest here are expressed by two different start codons of the viral C gene. Unlike the related HBcAg which activates type 1 T helper (Th1) cells leading to immune attack, the HBeAg activates Th2 cells which promote immune tolerance.

Development of Immune System Tolerance for the Treatment of Autoimmune Disease

The present invention provides a therapeutic method for the treatment of autoimmune or autoinflammatory diseases by first breaking down the dysregulated immune system and then reprogramming the immune system to restore tolerance to the patient's self-antigens by induction of antigen specific regulatory T cells. The inventors have shown that only with the combination of apoptosis, phagocytes, and antigen can antigen-specific regulatory T cells (Treg) cells be optimally generated to develop long-term immune tolerance.

A Novel Rapid Point-of Care Diagnostic Method for Infectious and Autoimmune Diseases

Rapid point-of-care, antibody-based testing is not available for the diagnosis of autoimmune and most infectious diseases. For detecting autoantibodies associated with most autoimmune conditions, fluid-phase immunoprecipitation assays are required. However, these assays usually involve radioactivity and are not feasible for point-of-care applications. The subject invention describes methods of using neodymium magnet for diagnosis of infectious and autoimmune diseases including lupus, Sjögren's syndrome, type I diabetes, HIV and Lyme disease.

Polyclonal Antibodies to Apolipoprotein L1 for Use in Basic Science Research

This technology includes antibodies to apolipoprotein L1 (ApoL 1) to be used in basic science laboratory studies. ApoL 1 is a protein that is present within cells and circulates as component of high-density lipoprotein. Its functions are not well understood. Recently APOL 1 genetic variants have been shown to be highly associated with kidney disease in African Americans.

Truncated Methanocarba Adenosine Derivatives as A3 Adenosine Receptor Antagonists

Novel A3 adenosine antagonists available for licensing. A3 receptors are particularly highly expressed in inflammatory cells, making it a potentially desirable target for inflammatory diseases. This technology relates to highly specific antagonists and partial agonists of A3 adenosine receptors, which are negatively coupled to adenylate cyclase and have been broadly implicated in inflammation, cardiovascular disease, endocrine conditions and cancer. Further, A3 adenosine receptors have been implicated in asthma and glaucoma.

Monoclonal Antibodies for Detection of Stachybotrys chartarum (a Fungus)

CDC NIOSH researchers have developed a simple and rapid detection technique for Stachybotrys chartarum (a type of mold that commonly grows on wet building materials) by producing monoclonal antibodies which reacts with proteins in Stachybotrys chartarum. These antibodies can be used in immunologic detection assays to detect and possibly quantify Stachybotrys chartarum in environmental samples, and to our knowledge, they do not cross react with other fungi.

Diisocyanate Specific Monoclonal Antibodies for Occupational and Environmental Monitoring of Polyurethane Production Exposure-related Asthma and Allergy and Clinical Diagnosis

CDC researchers have developed monoclonal antibodies useful as diagnostics for diisocyanate (dNCO) exposure and for toxicity characterization of specific dNCOs. Currently, dNCOs are used in the production of all polyurethane products and are the most commonly reported cause of occupational-induced asthma and also linked to allergic contact dermatitis. Presumptive diagnosis of dNCO asthma is presently dependent on criteria such as work history, report of work-related asthma-like symptoms and nonspecific airway reactivity to methacholine challenge.

Cylindrical Handle Dynamometer for Improved Grip-Strength Measurement

CDC researchers have developed an improved dynamometer device and method for measuring maximum hand grip force or grip-strength. Human test subjects were used in conducting experiments to evaluate the handle and to assess the measurement method. In contrast to the currently used "Jamar handle" grip strength dynamometer devices, the cylindrical handle proved to be able to determine the overall grip strength for a subject, as well as show the grip force distribution around the circumference of the handle.

Improved Acoustic Plethysmograph System for Noninvasive Measurement of Pulmonary Function

CDC researchers have developed a novel acoustic whole body plethysmograph (AWBP) that allows measurement of tidal volume in lab animals, independent of gas compression in the lung. This system provides particular advantages over the traditional whole body plethysmograph (WBP) when measuring model animals with increased gas compression due to increased airway resistance or increased acceleration in the breathing pattern.
