Method for Inducing T-Cell Proliferation

This technology relates to the use of thymic stromal lymphopoietin (TSLP) to induce CD4+ T cell proliferation. This proliferation could be of particular relevance for patients in whom this cell population has been significantly reduced by HIV/AIDS or other conditions resulting in immunodeficiency. The proliferation of isolated CD4+ T cells can be induced through direct contact with TSLP or a nucleic acid encoding TSLP.

Versatile Reagent For Detecting Murine Leukemia Viruses

Monoclonal antibodies directed at the proteins of murine leukemia viruses (MuLVs) have some value as immunological reagents, but differ greatly in their applicability. The kit described in this invention uses a monoclonal antibody designated 83A25, which identifies almost all ecotropic, xenotropic, polytropic, and amphotropic MuLVs. It can be used in a wide variety of procedures, including focal immunofluorescence assays on live or fixed monolayers, immunoblotting, immunoprecipitation, immunohistochemical, and flow cytometric procedures.

Conjugate Vaccine for Neisseria Meningitidis

The invention discloses a vaccine which comprises lipooligosaccharide (LOS) isolated from N. meningitidis and conjugated to a carrier protein. The invention also discloses a method of making the acellular vaccine. The method consists of two main steps. In the first step the lipooligosaccharide (LOS), chosen so it does not contain the lacto-N-neotetraose human antigen (LNnT), is detoxified by a novel procedure which uses hydrazine to remove the O-linked fatty acids. In the second step, the detoxified LOS (dLOS) is covalently conjugated to a carrier protein such as Tetanus Toxoid (TT).

Methods and Compositions for the Inhibition of SARS-CoV Replication Propagation and Transmission

Available for licensing and commercial development is a method of inhibiting SARS-CoV replication, propagation and transmission using 2-cyano-3,12-dioxooleana-1,9-dien-28-oic (CDDO). Severe acute respiratory syndrome (SARS) is an infectious atypical pneumonia that has recently been recognized in patients in 32 countries and regions. The atypical pneumonia with unknown etiology was initially observed in Guangdong Province, China.

Monoclonal Antibodies That Bind or Neutralize Hepatitis B Virus

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.

Parvovirus B19 Receptor And Parvovirus B19 Detection

The claimed invention provides a method of detecting the presence of a parvovirus in a sample. Parvoviruses infect animals and man. In man, the only known pathogenic member of this family is parvovirus B19. The inventors have identified the parvovirus B19 receptor which provides for a method to diagnose, prevent, and treat parvovirus infection utilizing the binding affinity for the receptor.

Monoclonal Antibody for Lyme Disease Diagnostic and Research

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.

Viral Entry or Replication Inhibitors

The Tec family of tyrosine kinases, consisting of five family members Tec, Btk, Itk, Rlk, and BMX, are key regulators of signaling pathways of T lymphocytes. Many existing antiviral therapies rely on inhibition of viral replication, which leads to emergence or selection of resistant viruses. The current technology provides an alternative method for prevention or treatment of viral infection through administration of a Tec tyrosine kinase inhibitor. Such inhibitors can be siRNA, small chemical compounds, antisense or antibody.

Molecules for Studying Cellular Immune Responses to Vaccines and Therapeutics

HLA molecules are indispensable and invaluable tools for efficient vaccine research and development. Infectious diseases are the second leading cause of death among adults and the most prominent cause of death in infants and children worldwide. Thus, rapid availability of prophylactic vaccines for cancers and infectious diseases such as HIV, HPV, influenza and diarrheal and respiratory diseases is a world-wide health concern.
