I understand the basic biological difference. The mechanism of action of the protein described in the paper, apparently successfully tested against a wide variety of unrelated viruses in mice, seems to be to unfurl itself and trigger apoptosis only in the presence of single-strand viral RNA of sufficient length. I'm asking why that hasn't been followed up on.
