 these AAV viruses. So instead, what we're doing is delivering a much smaller protein that really is sort of an adapter. It just binds to the DNA and then it grabs your natural machinery for shutting down genes. So all we have to do is put this little adapter in and the adapter very nicely fits into an AAV. And then like gene editing, this process identifies the right bit of all the DNA to say, right, stop producing this prime protein.
