Production of viral vectors for gene therapy applications.
Advances in cell culture engineering, cell metabolism, bioreactor design and operation, and downstream processing will all positively impact the bioprocessing of viral vectors. Design of appropriate vectors and tailoring of packaging cells to support more productive infections will be of paramount importance for production of high-titer and high-quality vectors. Furthermore, quantitative analysis of the infection parameters during virus propagation, such as time of infection, multiplicity of infection, the length of replication cycle, virus half-life, and burst size, will also be important to the process optimization. Finally, procedures for separation, purification and formulation of vector preparations have to be further developed.
