Abstract: A replication-defective HIV particle pseudotyped with vesicular stomatitis virus G protein (VSV-G). The pol gene of the HIV genome in the particle is modified to inactivate the pol reverse transcriptase and protcase activity. This pseudotyped HIV particle can infect many cell types, including human and simian cells, and only undergoes one round of replication. Furthermore, a virus-specific immune response can be detected in mice immunized with the VSV-G pseudotyped replication-defective HIV.
Abstract: An innovative detection system for detecting small numbers of target analytes is disclosed. This system provides a novel method for attaching multiple copies of reporter groups to a single site on an analyte of interest. This system preferably comprises a virus capsid enclosing multiple detectable reporter groups, and a linking molecule which is capable of linking the capsid to the analyte of interest.
Abstract: The invention relates to a method for the removal of leucocytes from blood which comprises bringing blood that comprises infected leucocytes into contact with an adsorbent carrier that has a greater affinity for infected, activated and/or defective leucocytes than for uninfected leucocytes especially cellulose acetate. The method can be used in the apheresis treatment of diseases caused by pathogenic organisms, for example, HIV, HCV or malaria. It is especially useful for treatment of HIV.

Abstract: Disclosed is a method for treating infection with a pathogen. The method involves administration of: (1) a substance which induces active pathogen replication in a cell latently infected with HIV and (2) an anti-pathogen drug. Also disclosed are methods for expanding CD4+ T cells from peripheral blood mononuclear cells isolated from human subjects in the presence of an antiretroviral drug and for treating HIV infection by infusing the expanded CD4+ cells into HIV-infected patients.
Abstract: The invention provides compositions and methods for stimulating a Th1-like response in vitro. Compositions include fusion proteins and conjugates that contain at least a portion of a heat shock protein. A Th1-like response can be elicited by contacting in vitro a cell sample containing naive lymphocytes with a fusion protein or conjugate of the invention. The Th1-like response can be detected by measuring IFN-gamma produced by the cell sample.

Abstract: The present invention comprises spumavirus isolated from humans. More specifically, the spumavirus of the present invention was isolated from humans who had exposure to nonhuman primates. Importantly, the spumavirus of the present invention or antibodies to the spumavirus can be used to detect the presence of spumavirus or antibodies in body fluids, for pathogenicity studies of related viruses, and as a vector for gene therapies. The spumavirus of the invention can also be used for treatment of conditions in humans due to the presence of rapidly dividing cells and for recombinant live virus vaccination.

Abstract: A drug screening assay for identifying compounds for their potential effects on the long chain fatty acid dependant intracellular membrane anchorage sites of lipoproteins. Membranes-anchoring-target are incubated in the presence of the compound to be tested and the proportion of the target that is released by the compound is detected and quantitated. The benchmark for this assay are the prenylated proteins such as the farnesylated and palmitoylated oncogenic ras trigger proteins which are displaced from their anchorage at the intracellular plasma membrane by derivatives of Farnesyl Thiosalicylic Acid (FTS). The assay is adaptable to flexibly assay a large variety of anchored targets using a wide range of labeling and detection techniques in test wells, tissue culture, and in animals as injected cells or transgenic, thereby directly addressing a wide range of pharmacologically relevant needs.
