Abstract:
Methods and compositions are provided for screening candidate antiviral agents using cells containing subgenomic viral replication systems such as replicons and minigenomes. The methods involve the simultaneous assay of more than one subgenomic viral replication system. Compositions useful for these methods are also provided.
Abstract:
The present invention relates to a method of detecting whether a target animal is Bovine Viral Diarrhea Virus (BVDV) positive or negative by determining whether a gp48 protein-specific reagent binds to a gp48 Bovine Viral Diarrhea Virus protein or protein fragment, which retains antigenic specificity, from a target animal's tissue sample.
Abstract:
A method of causing irreversible damage to stealth virus infected cells, based on exposing the infected cells to magnetic energy. The method of the present application specifically relates to the culturing of stealth viruses from an infected subject and determining the presence of magnetic and/or paramagnetic material in the stealth virus infected culture. Magnetic and/or paramagnetic material can also be found in cultures of bacteria that are infected with the patient's stealth virus. The cultured stealth virus infected cells are tested for susceptibility to cell damage caused by a magnetic field that is not significantly injurious to normal uninfected cells. The presence of magnetic and/or paramagnetic material in the stealth virus culture and the demonstration that exposure to a strong magnetic field can cause damage to stealth virus infected cells, form the basis of therapy for stealth virus infected patients and animals. The therapy comprises exposing stealth virus infected cells within a patient to a magnetic field of sufficient strength to cause damage to cultured virus infected cells. Magnetic energy therapy is especially applicable as therapy for stealth virus associated cancers in which the stealth virus isolated from the cancer patient can be shown to induce the formation of magnetic and/or paramagnetic material.
Abstract:
The present invention relates to bovine viral diarrhea virus (BVDV) virus-like particles, a polycistronic RNA and DNA corresponding thereto encoding a polyprotein of BVDV structural proteins that are sufficient to form BVDV virus-like particles, a viral vector encoding factors and structural proteins for the assembly of BVDV virus-like particles, a vaccine comprising BVDV virus-like particles, a diagnostic kit and methods for preparing BVDV virus-like particles.
Abstract:
A novel bacteriophage RM 378 of Rhodothermus marinus, the nucleic acids of its genome, nucleic acids comprising nucleotide sequences of open reading frames (ORFs) of its genome, and polypeptides encoded by the nucleic acids, are described.
Abstract:
The present invention provides methods of isolation and purification of Strepomyces griseus trypsin (SGT) from pronase in a single affinity chromatography step and uses of the purified SGT.
Abstract:
The present invention relates generally to viral variants exhibiting reduced sensitivity to particular agents and/or reduced interactivity with immunological reagents. More particularly the present invention is directed to hepatitis B variants exhibiting complete or partial resistance to nucleoside analogues and/or reduced interactivity with antibodies to viral surface components. The present invention further contemplates assays for detecting such viral variants which assays are useful in monitoring anti-viral therapeutic regimes.
Abstract:
This invention relates to an isolated nucleic acid fragment encoding a transcription factor. The invention also relates to the construction of a chimeric gene encoding all or a portion of the transcription factor, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the transcription factor in a transformed host cell.
Abstract:
The present invention relates to novel chemical compounds, methods for their discovery, and their therapeutic use. In particular, the present invention provides benzodiazepine derivatives and methods of using benzodiazepine derivatives as therapeutic agents to treat a number of conditions associated with the faulty regulation of the processes of programmed cell death, autoimmunity, inflammation, and hyperproliferation, and the like.
Abstract:
The invention provides HSV antigens that are useful for the prevention and treatment of HSV infection. Disclosed herein are antigens and/or their constituent epitopes confirmed to be recognized by T-cells derived from herpetic lesions or from uterine cervix. T-cells having specificity for antigens of the invention have demonstrated cytotoxic activity against cells loaded with virally-encoded peptide epitopes, and in many cases, against cells infected with HSV. The identification of immunogenic antigens responsible for T-cell specificity provides improved anti-viral therapeutic and prophylactic strategies. Compositions containing antigens or polynucleotides encoding antigens of the invention provide effectively targeted vaccines for prevention and treatment of HSV infection.
