Retrovirus vectors derived from avian sarcoma leukosis viruses permitting transfer of genes into mammalian cells and therapeutic uses thereof

   
   

Recombinant avian sarcoma leukosis virus (ASLV)-derived retrovirus vectors having an expanded host range are described. The host range is expanded by the replacement of the ASLV envelope gene by an envelope gene from a virus capable of infecting both mammalian and avian cells. The resulting recombinant ASLV-derived retroviral vectors can replicate efficiently in avian cells, infect both avian and mammalian cells in high titer, and are replication-defective in mammalian cells. Thus, they are quite safe and advantageous for use in gene therapy and vaccines.

Рекомбинатный avian вирус лейкоза саркомы (описаны АСЛВ)-vyvedennye векторы retrovirus имея расширенный ряд хозяина. Ряд хозяина расширен заменой гена габарита ASLV геном габарита от вируса способного заражать и mammalian и avian клетки. Приводя к рекомбинатные АСЛВ-vyvedennye retroviral векторы могут скопировать эффективно в avian клетках, заразить и avian и mammalian клетки в высоком титре, и репликаци-nepolnoqenny в mammalian клетках. Таким образом, они довольно безопасны и выгодны для пользы в терапии и вакцинах гена.
