> We (WHO working group) did talk to the SSI but they were very cagy (as you might expect). But they sharing isolates now through the WHO I believe. Yup, no surprise there - unfortunately. And yes - I believe they have shared the isolates widely now (including withUS) labs, so hopefully we'll learn more soon. I think they got a little surprised by how strongly the scientific community pushed back at them for not releasing data, so hopefully they have learned a lesson. (unfortunately way too much focus has been put on the mistakes here though - it's really important we remember that the main issue here is a parallel (raging) epidemic in mink).

In context

A single line often inverts meaning once you see what it answers, so neighbouring messages are always shown.

One thing to be a data parasite (which implies some relationship to the host) and a data thug/thief.

Thanks Andrew for sharing - very interested to get your insights into this. Will keep confidential - A LOT of disagreement in DK about how to handle that (most of those discussions driven by people that have no background in any of this...).

FWIW - the 69/70 S deletion comes at a region that is disordered at least in some spike structures (reddish sphereshere). It's at the top of the spike but not close by to Y453 (bluish) so not obvious why the might be linked. Not likesubstructures that interact (for example the 6 helix bundles) where you expect compensatory/complementarymutations. [shared file(s): image.png]

Some wild speculation if you want to "connect" 69/70 to 453. MERS-CoV uses both [either?] a protein and a sialicacid receptor. HKU1 uses sialic acid and of course SARS CoVs use ACE2. What's not known [here's the speculation] is if the NTD of SARS-CoV2 (where the 69/70 deletion is actually part of a receptor binding domain forsialic acid or other molecule. If so a deletion in the NTD affecting binding to this receptor might affect entry driven bythe CTD. Receptor swapping is definitely a thing in HIV (chemokine receptors). [shared file(s): image.png]
