| 摘要 |
The present invention relates to the production of recombinant viruses and/or recombinant viral proteins using cells that can grow in suspension and in serum-free conditions without the requirement of any animal- or human-derived components. In particular, the invention relates to the production of recombinant alphaviruses that are suitable for use in vaccines and in gene therapy applications. For example, Semliki Forest Virus particles carrying a heterologous gene of interest (e.g., an antigen) are produced on El-transformed non-tumorous human cells, preferably derived from primary retinoblasts, such as PER.C6(TM) cells.
