Anti-Plasmodium Compositions and Methods of Use

This invention describes methods and compositions of peptides that inhibit the binding of Plasmodium falciparum (P. falciparum) to erythrocytes. Malarial parasites enter the red blood cell through several erythrocyte receptors, each being specific for a given species of Plasmodia. For P. falciparum, the erythrocyte binding antigen (EBA-175) is the ligand of the plasmodia merozoites that interacts with the receptor glycophorin A on the surface of red blood cells.

Human T Cell Line Chronically Infected With HIV

A stable line of human T cells (ACH-2) was developed in which cells infected chronically with the AIDS virus (HIV) remained nonproductive prior to exposure to phorbol esters or human cytokines. This situation mimics the latent state of HIV and the development of AIDS in humans and indicates that the full-blown disease may be triggered by cellular-derived substances (e.g., cytokines). This is the first description of such a cell line.

Attenuated Human Parainfluenza Virus (PIV) for Use as Live, Attenuated Vaccines and as Vector Vaccines

The identified technologies describe self-replicating infectious recombinant paramyxoviruses with one or more attenuating mutations, such as a separate variant polynucleotide encoding a P protein and a separate monocistronic polynucleotide encoding a V protein, or at least one temperature sensitive mutation and one non-temperature sensitive mutation. Compositions and methods for recovering, making and using the infectious, recombinant paramyxoviruses as described are also included (e.g. recombinant human parainfluenza virus type 2 (HPIV2)).

Amelioration of Inflammatory Arthritis Targeting the Pre-ligand Assembly Domain (PLAD) of Tumor Necrosis Factor Receptors

The invention relates to compositions of matter and methods for treating arthritis by modulating Tumor Necrosis Factor Alpha (TNF-alpha) signaling. TNF-alpha plays a key role in the pathogenesis of numerous diseases including rheumatoid and septic arthritis, and other autoimmune and inflammatory diseases. TNF-alpha mediates its effects through receptors that contain a Pre-ligand Assembly Domain (PLAD). The inventors have discovered compounds that interfere with PLAD can block the effects of TNF-alpha in vitro.

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.

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.

The Use of an Inducible Plasmid Vector Encoding for Active TGF-beta for the Treatment of Autoimmune Diseases

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.

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.
