    摘要: The present invention provides a method of determining if a tumor cell is susceptible to killing by a chemotherapeutic agent, comprising: (a) providing a tumor cell; (b) infecting said tumor cell with a herpes simplex virus or a herpes simplex virus defective in an immediate early gene selected from the group consisting of ICP27, ICP4, and ICP22; and (c) determining the presence of apoptotic killing of said tumor cell, wherein the presence of apoptotic killing is indicative of susceptibility to said chemotherapeutic agent. Chemotherapeutic agent may include doxorubicin, etoposide, paclitaxel, cisplatin, or 5-fluorouracil. The present invention also provides a herpes simplex virus promoter construct having a lacZ gene to assess tumor resistance to chemotherapeutic agents.

    摘要: 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.

    摘要: The invention comprises a novel virus that can kill mammalian cancer cells efficiently. The virus produces a novel protein that converts two non-toxic prodrugs into potent chemotherapeutic agents. These chemotherapeutic agents are produced locally and help the virus kill the cancer cells as well as sensitize them to radiation. In preclinical studies, the virus has proven effective at killing a variety of mammalian cancer cells either alone or when combined with prodrug therapy and/or radiation therapy. The invention may provide a safe and effective treatment for human cancer.

    摘要: The present invention provides a method for preparing HSV vectors. The method comprises co-transfecting a source vector and a mutating cassette together into a population of appropriate host cells, such that homologous recombination occurs between the mutating cassette and the source vector whereby the mutating cassette replaces a region of the HSV genome. The mutating cassette has a unique restriction site not present in the sequence of the vector. The method further comprises plaquing the co-transfected host cells, selecting plaques in which recombination has occurred between the source vector and the mutating cassette, and isolating the viral DNA from the plaques. The isolated viral DNA is digested with a restriction endonuclease appropriate for cleaving the viral DNA at the unique restriction site within the mutating cassette to produce two viral polynucleotides. Following purification, the two viral polynucleotides can be ligated to form an HSV vector comprising the two viral polynucleotides. Alternatively, the two isolated viral polynucleotides can be recombined with an insertion cassette to form an HSV vector comprising the insertion cassette at the former locus of the unique restriction site. The present invention further provides a mutant vector, particularly an HSV vector constructed in accordance with the method for the present invention. The present invention further provides a multigene HSV vector, particularly a multigene HSV vector for cancer therapy.

    摘要: This invention relates to a method for identifying non-essential genes of the human cytomegalovirus (HCMV) genome through the insertion of a .beta.-glucuronidase marker gene into a specified HCMV gene, such that, if the product of the HCMV gene is not expressed, the gene is identified as non-essential for replication of HCMV. This invention also relates to a method of screening for compounds which inhibit HCMV by the insertion of the .beta.-glucuronidase marker gene into a HCMV gene, such that the enzyme marker is expressed and cleaves a conjugate chemical substrate in an assay system to yield a detectable fluorescing product or to result in a color change. This invention further provides the gene responsible in HCMV early cytopathic effect.
