The Main protease (Mpro) from SARS-CoV-2 triggers plasma clotting in vitro by activating coagulation factors VII and FXII
“Although the connection between COVID-19 and coagulopathy has been clear since the early days of SARS-CoV-2 pandemic, the underlying molecular mechanisms remain unclear. Available data support that the burst of cytokines and bradykinin, observed in some COVID-19 patients, sustains systemic inflammation and the hypercoagulant state, thus increasing thrombotic risk. Here we show that the SARS-CoV-2 main protease (Mpro) can play a direct role in the activation of the coagulation cascade.”

NEW PREPRINT! Another study about ABNORMAL BLOOD CLOTTING related to SARS-CoV-2, but unlike the others I've covered, this isn't related to the spike protein.

“NEW PREPRINT! Another study about ABNORMAL BLOOD CLOTTING related to SARS-CoV-2, but unlike the others I've covered, this isn't related to the spike protein.

Turns out that Mpro, a viral protease [pro-tee-ace], can START the cascade.

a thread written for everyone:

Here's the takeaway: The Main protease (Mpro) of SARS-CoV-2—an enzyme that cuts up viral polyproteins—can also cleave a few host coagulation factors in a way that ACTIVATES them and BEGINS the blood clot cascade.”
