A method to induce an immune response in a host in need thereof, comprises administering to the host, recombinant lentiviral vector particles comprising: a) a GAG polypeptide or a functional GAG-polypeptide derivative; b) a POL polypeptide or a functional POL-polypeptide derivative ; c) an ENV polypeptide or a functional ENV-polypeptide derivative; and d) a recombinant polynucleotide. The recombinant polynucleotide comprises a transgene placed under the control of regulatory signals for transcription and expression, regulatory signals, of lentiviral origin, for reverse transcription, expression and packaging, and a polynucleotide comprising a cis-acting central initiation region (cPPT) and a cis-acting termination region (CTS). The regions are of lentiviral origin and are inserted in a functional orientation with the regulatory signals of lentiviral origin. The polynucleotide forms a DNA triplex during reverse transcription.
摘要:
A recombinant vector comprising a polynucleotide containing a cis-acting central initiation region (cPPT) and a cis-acting termination region (CTS) is disclosed. These regions are of retroviral or retroviral-like origin. The vector further comprises a defined nucleotide sequence (transgene or sequence of interest) and regulatory signals for reverse transcription, expression, and packaging, wherein the regulatory signals are of retroviral or retroviral-like origin. In some embodiments the vector is incorporated into compositions for therapeutic purposes. In other embodiments the vector is incorporated into immunogenic compositions, The vector is also useful for methods such as ex vivo transfection or ex vivo transduction of non-mitotic differentiated cells.
