Abstract:
Recombinant adeno-associated viral vectors (rAAV) have been widely used as gene therapy vectors in clinical trials. Here, we reviewed the genomic structures and replication mechanisms of wt-AAV. Then, the assembly of capsid and the encapsidation of genomic DNA, two major events during AAV pakaging, was discussed in detail. Although the overall pattern of virus assembly and encapsidation is known, the molecular mechanisms and the structure-function relationship involved in these processes are not well understood. Further elucidatation of these processes may improve the production technology of rAAV and develop gene drug based on rAAV.
