<p>This invention provides a Togavirus-amplified retrovirus vector and a novel method for packaging a retrovirus cassette that contains a heterologous nucleic acid, which is amplified in a packaging cell cytoplasm by a Togavirus vector. The retroviral cassette is packaged into infectious retrovirus particles by retroviral packaging cells. These retroviral particles carrying the retroviral packaging cassette are then used to infect host cells.</p> |
