    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 present invention relates to recombinant cells as well as to methods for the generation of non-segmented negative-sense single-stranded RNA viruses (NNV or mononegavirales) from cloned deoxyribonucleic acid (cDNA), especially from measles virus and in particular from attenuated strains such as those approved for vaccination, in particular from the attenuated Schwarz measles virus and various recombinant Schwarz measles-based viruses expressing heterologous sequences. Such rescued viruses can be used, after amplification, as vaccines for immunization against measles and/or against the heterologous peptides or proteins expressed.
