The biggest problem of Gene Editing & Gene therapy is delivery - how to deliver a genetic payload to the exact desired location. Here’s a great Infograph which shows which BioTech companies use Viral delivery methods (AAVs, LVs) compared to non-viral platforms (NLPs). $XBI The biggest problem of Gene Editing & Gene therapy is delivery - how to deliver the genetic payload to the exact desired location. Here is a great Infograph which shows which BioTech companies use Viral (AAVs) delivery methods compared to non-viral platforms (NLPs). 2/Must of the companies - as you can see in the graph m☝️- use a viral based delivery platform for Gene Therapy / Gene Editing treatments, mostly AAV - Adeno-Associated Virus based delivery. AAV is a naturally occurring virus being transformed into a delivery mechanism by replacing its viral DNA with new DNA, thus making it a precisely coded vector & it is no longer considered a virus, as most of its viral components have been replaced.
