Previous research has suggested that the spike protein may be involved in the creation of small blood clots. Blood contains fibrin, which helps blood clot when blood vessels are damaged. As the wound begins to heal, the clot should be broken down by plasmin in the blood.
This time, the researchers mixed the amyloid-producing fragments of the spike protein with these body substances in a test tube and found that the resulting fibrin coagulation could not be broken down by plasmin in the usual way. This newly discovered mechanism may be responsible for the similar microthrombosis observed in patients with severe and prolonged COVID-19.
