Thanks for all you do! It's so wonderful to see you're illuminating these connections in ways that hopefully can help save lives. I see there's a new paper you may have seen that discusses a note on amyloid terminology--their paper states, "We recognize that there has occasionally been confusion in our use of the term ‘amyloid’ to describe amyloidogenic blood clotting, as blood is not seen as a source of the classical amyloidoses. While we could have used another term, the structures and staining of these blood clot fibres, presumably consisting of the ordered β-sheet architectures necessary (i) to bind fluorogenic amyloid stains and (ii) to be resistant to the normal sources of proteolysis, do reflect the well-established term ‘amyloid’. In addition, there is a very simple discrimination between ‘classical’ amyloids and those fibrin-rich amyloids that are our focus here: this is that the amyloid fibrils seen in classical amyloidoses tend to be ca 5–25 nm or so in diameter whereas those in fibrin amyloid microclots tend to be in the range 50–150 nm or even more. They are thus easily distinguished microscopically, even without the greater analytic power afforded by proteomics, antibody staining, and so on. However, to avoid such ambiguity in the future, we consider it sensible to refer to the kinds of fibrin-based amyloids we are speaking about as fibrinaloids"
