Dear all, Before the seminar ends I just want to share my ideas about antiviral approaches and share non official result of a simple experiment. Viruses have an envelope made of cell membrane. They have a core, made of protein and spikes, made of glycoproteins which are molecularly similar to our (mammalian) structures. Therefore if we try to kill them with a chemical or a physical agent that means we also harm ourselves. (Thats why we don't have widely used effective antiviral drug till now). On the other hand, as much more organized beings we have ability of regeneration and hemostasis which viruses' don't have. I think this difference is the key of producing "antiviral agent". For example viruses have envelope and they lost their infectivity if they lost their envelope. If we produce a chemical or physical agent which reversibly harm (makes little pores) on envelope (and also on cell membrane (because they both the same molecular structure)) virus wont be healed but cell membrane will be healed. We kill the virus and let the cell harmed but alive. Starting from this idea, I tried an organic extract over PPR infected cell culture and the first results were pretty much encouraging. With appropriate dilution, organic extract prevented CPE (most probably killed the virus) and keeped monolayer cell alive. http://imageshack.com/a/img802/6981/acd9.png Even though may be it is not easy or possible for us to get appropriate density which kills the virus in blood and other body fluids without having allergic reactions. It is good to know we have something which can kill virus and apparently doesn't harm cells. Just wanted to share it to let further ideas. And hope to share official results in future. It was really beneficial being here getting knowledge from experiences. want to thank all. Take care.
