Agreed, but part of the party line is "It attaches to ACE2 receptors OMG!" Nor is furin cleavage a completely unique or new thing. I just want to know that you don't mean they have not heard these terms or something. That would be like not knowing about D2 receptors or COMT polymorphisms. That's all I mean to clarify and I suppose I may be acting a bit obtuse by it all. Sometimes I like a little too much clarity (for my own personal understanding-others may have gotten it just fine!). Now, I have personally noticed that people DO seem to react with blank expression or discomfort with mention of nAChR's and certainly CRISPR tech and chimeric "therapeutics", because those things are out of the realm of most real-world clinical practice. Anyway, thank you for your patience as I sift things through!
