摘要:
The invention involves the detection of virally infected cells by antibodies or antibody fragments which selectively bind to TSG101. TSG101 is on the surface of mammalian cells, and thus available for detection by antibodies, during viral budding—a phenomenon wherein viral particles escape a virally infected cell after propagation in that cell, so as to infect other cells. To achieve budding, a protein, TSG101 is “hijacked” and misdirected to, or mis-expressed on, the surface of the infected cell. Antibodies can be used to selectively detect such infected cells. Certain TSG101 antibodies may provide therapeutic benefit when administered to infected mammals.

The invention reflects enhanced antibody expression of an antibody of interest by cell lines transformed by random homozygous gene perturbation methods to either increase or decrease the expression pattern of a gene of the cell line other than the antibody of interest. The transformed cell line exhibits specific productivity rates, SPR, for the RHGP transformed cell liens of 1.5 or more, as compared with the antibody expressing cell line parents prior to transformation by RHGP. A knock out or anti-sense construct may be devised to reduce expression of the target gene, a promoter may be inserter to enhance expression of the target gene. The antibodies expressed by the transformed cell lines exhibit the binding properties of their parent cell lines prior to transformation with RHGP, and increase Total Volumetric Production of said antibody by said cells in a given volume.

XMRV appears to be related to both prostate cancer if it infects a male germ cell and chronic fatigue syndrome in both sexes. (If the virus does not infect a germ cell). Prostate cancer cells exhibit TSG101 on the surface only upon infection with a virus like XMRV. Antibodies to TSG101 can be effective diagnostics to identify individuals with a predisposition to prostate. They can also be used in place of current diagnostics to confirm the presence of prostate cancer. TSG101 antibodies, when administered in vivo, exhibit the ability to reduce tumor size, suppress metastatic transformation and extend survival.

Caspace inhibition provides inhibition of viral infection across a wide collection of caspaces and viruses. Caspace inhibition, the prevention of the formation of active caspaces, can be achieved either through gene therapy, protein binding an inhibition, or through small molecule administration. Examples for small molecule inhibition allow the formation of a pharmacaphore to identify more and more active small molecules.
摘要:
A method for identifying host genes and encoded proteins for potential targets for therapeutic intervention employs a Gene Search Vector that is either lentivirus or MMLV-based, and can be used to interrogate an entire cell genome without prior knowledge of the genomic sequence. This Random Homozygous Gene Perturbation (RUGP) technique is rapidly verifiable and is used to identify potential host targets for intervention for influenza, HIV and other viral infections. Using Thermal Assymetric Interlaced (TAIL)-PCR, the period for identification of promising targets is reduced from months to weeks or less. Specific targets including PTCH1, Robo1 and Nedd4 are reviewed in detail.
摘要:
Compounds that possess anti-infective activity are described. Methods of using these compounds for the treatment or prevention of infectious diseases such as acquired immunodeficiency syndrome (AIDS) are also described. The compounds inhibit HIV infectivity and do not exhibit significant cytotoxicity in HIV producing cells.
