Discovery of natural adeno-associated virus variants and their characterization as potential gene therapy vectors
Save as calendar entryRecombinant adeno-associated viruses (rAAVs) are the ideal vectors for human gene therapy because of their excellent safety profiles and therapeutic transgene delivery efficacies. Efforts to discover novel AAVs with improved transduction efficiencies and reduced host immunities continue to be major focuses for the gene therapy field. Using single molecule, real-time (SMRT) sequencing of proviral capsid libraries isolated from >800 human surgical specimens, we discovered a collection of novel clade B, C, and E variants. One of our lab’s current research pursuits is to test these variants in mice and cynomolgus macaques under various routes of administration to target a range of tissue and cell types of interest.
A variant we have named AAVv66, was recently identified as the most abundant pro-viral capsid variant in a clinical pancreatic neoplasm sample that was observed to harbor a high diversity of capsid sequences when profiled by high-throughput sequencing approaches. The AAVv66 capsid harbors 13 residues that are unique from AAV2, most of which are within defined variable regions of VP3. Aside from exhibiting favorable tropism in the CNS following intrahippocampal injections, we found that AAVv66 displays better packaging efficiencies than prototypical AAV2; thus demonstrating another important facet as a promising gene therapy capsid.
