Abstract: The invention involves viral vectors that can be used to tranduce a target cell, i.e. to introduce genetic material into the cell. The targets of interest are eukaryotic cells and particularly human cells. The transduction can be done in vivo or in vitro. More particularly the invention concerns viral vectors that have chimeric envelope proteins and contain the IgG-binding domain of protein A. These vectors when used in conjunction with antibodies targeting a particular cell are particularly useful for gene therapy.

Abstract: The invention concerns an improvement in the art of inserting and expressing foreign gene into eukaryotic cells. The invention particularly concerns methods and compositions whereby viral vectors can be used to insert and express foreign genes into specifically cells having particular differentiation antigens. A method of determining which differentiation antigens can be used is taught. The invention encompasses complexes of viral particles and adapters that cause the binding and internalization of the vector particles such that a gene of interest in the particle is expressed.

Abstract: The present invention relates to methods and compositions that can be employed to introduce toxins and nucleic acids into the cytoplasm or nucleus of a eukaryotic cell, particularly a cell of a higher vertebate. The invention particularly concerns the use of a fusion protein of streptavidin and protein A sequences to form a non-covalent complex of a toxin or nucleic acid and an antibody.

Abstract: Disclosed herein are antiviral agents, pharmaceutical formulations comprising effective amounts of these agents and methods for treating mammals suffering from infections caused by viruses. The agents are analogs, isomers, homologs, derivatives and salts of aromatic polycyclic diones.

Abstract: The present invention concerns the field of molecular genetics and medicine. Particularly, it concerns a gene, FXI-T1, whose mRNA levels are increased in fractionated X-irradiation induced leukemias and methods of using FXI-T1 to classify tissue samples for medical purposes. Specifically, the invention concerns the murine and human homologs of FXI-T1.

Abstract: Target cell specificity of delivery vectors is provided by incorporation of a target cell specific binding domain by the use of any binding domain, which binds specifically to a binding site on the target cell. The binding site may be endogenous to the target cell, provided by engineering the target cell, or a suitable binding site may be associated with the target cell. Target cells may also be associated with a CVR polypeptide to provide specificity for the delivery vector. The association of the CVR polypeptide confers target cell specificity for a second virus host cell range, which specificity differs from the viral host cell range of the endogenous target cell or animal host cell viral receptors. The CVR polypeptide may thus comprise a chimeric virus binding site which binds a second virus env binding domain specific for a second virus host cell range, selected from at least one of the group consisting of amphotropic, polytropic, xenotropic, ecotropic and tissue specific.

Abstract: T cell-mediated diseases in mammals are treated using compositions comprising a polycyclic aromatic compound, preferably hypericin or pseudohypericin, and related compounds, including isomers, analogs, derivatives, salts, or ion pairs of hypericin or pseudohypericin. The above composition may be administered in combination with an immunosuppressive agent. Pharmaceutical compositions useful for treating a T cell-mediated disease comprise the above polycyclic aromatic compound, alone or in combination with an immunosuppressive agent. The compositions and methods are useful in treating diseases which include multiple sclerosis, myasthenia gravis, scleroderma, polymyositis, graft-versus-host disease, graft rejection, Graves disease, Addison's disease, autoimmune uveoretinitis, autoimmune thyroiditis, pemphigus vulgaris and rheumatoid arthritis. Psoriasis and systemic lups erythematosus.

Abstract: A method for treating a papilloma virus infection comprising topically administering hypericin which is effective to inhibit the replication, growth and/or the infectivity of the virus. The papilloma viruses include those capable of causing benign warts or a malignancy such as human papilloma virus-1 (HPV-1), HPV-2, HPV-6, HPV-11, HPV-16 and HPV-18.

Abstract: The present invention provides compositions, articles and methods for inactivating viruses present in whole blood and other body fluids. The method comprises contacting the body fluids with an effective amount of an antiviral compound. Blood bags, vacuum blood tubes, condoms, spermicidal jellies and vaginal lubricants containing effective amounts of the antiviral compounds are also provided.
