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.

Methods and Materials for Identifying Polymorphic Variants, Diagnosing Susceptibilities, and Treating Disease

This invention relates to materials and methods associated with polymorphic variants in two enzymes involved in folate-dependent and one-carbon metabolic pathways important in pregnancy-related complications and neural tube birth defects: MTHFD1 (5,10-methylenetrahydrofolate dehydrogenase, 5,10-methenyltetrahydrofolate cyclohydrolase, 10-formyltetrahydrofolate synthase) and methylenetetrahydrofolate dehydrogenase (NADP+ dependent) 1-like (MTHFD1L). These enzymes are extremely important in the promotion of DNA synthesis, a process that is critical for normal placental and fetal development.

Assay for the Detection of a Variety of Tumors in Biological Specimens

The inventors have developed methods and reagents for the detection of bone sialoprotein (BSP) in biological samples. The technology relates to the disruption of a serum complex that masks the majority of BSP from established detection systems. Furthermore, there is evidence that there may be a more acidic form of BSP secreted not by normal bone, but only by tumors. Detection of BSP in serum may be a good marker of various bone diseases and a variety of cancers including breast, prostate, lung, and thyroid.

AAV5 Vector and Uses Thereof

The invention described and claimed in this patent application provides for novel vectors and viral particles which comprise adeno-associated virus serotype 5 (AAV5). AAV5 is a single-stranded DNA virus of either plus or minus polarity which, like other AAV serotypes (e.g., AAV4, AAV2) requires a helper virus for replication. AAV type 2 has the interesting and potentially useful ability to integrate into human chromosome 19 q 13.3-q ter. This activity is dependent on the non-structural, Rep, proteins of AAV2.

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.

Treatment for Ichthyosiform Skin Diseases

A synthetic composition that contains the transglutaminase 1 (TGase I) enzyme and a lipid vesicle, which can be used to provide ameliorative therapy for inherited autosomal recessive ichthyoses (ARI). Icthyoses are rare inherited skin disorders that result in extensive scaling of the skin. Because this abnormality can affect heat and fluid transfer through the skin, individuals with this disease may have an increased risk for dehydration and skin infections. Each year, more than 16,000 babies are born with some form of ichthyosis. Ichthyosis affects people of all ages, races and gender.

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).

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.

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.
