    摘要: The present invention provides nucleic acid, vectors, viruses, and recombinant cells comprising triple-stranded structures, such as those resulting from central initiation and termination of HIV-1 reverse transcription at the center of HIV-1 linear DNA genomes. These triplex structures can act as a cis-determinant of HIV-1 DNA nuclear import, allowing infection of non-dividing target cells. In one aspect, the presence of the DNA triplex sequence in an HIV vector strongly stimulates gene transfer in hematopoietic stem cells. The invention also provides methods of using these triplex structures for making recombinant cells, as well as methods of using the recombinant cells to express proteins of interest both in vitro and in vivo.

    摘要: The medical device by which a modified Human Immunodeficiency Virus or virus-like structure is used as a transport medium to carry a payload of a quantity of anti-viral drug molecules to T-Helper cells in the body. The modified Human Immunodeficiency Virus or virus-like structure makes contact with a T-Helper cell by means of the modified virus's exterior probes or virus-like structure's exterior probes. Once the exterior probes engage the T-Helper cell's receptors, the modified virus or virus-like structure inserts into the T-Helper cell the quantity of medically therapeutic anti-viral drug molecules it is carrying. The anti-viral drug molecules exhibit an anti-viral effect when present inside the T-Helper cells thus assisting in repelling an infection by the Human Immunodeficiency Virus and the use of such a device significantly lowers the occurrence of unwanted deleterious side effects.
