The current COVID-19 pandemic has resurrected the concept of immunothrombosis as it is a relevant model to demonstrate the potentiating effects of the immune system and the coagulation system and the detrimental effects associated with their unrestrained activation, as evidenced by microthrombi and overt venous and arterial thrombi (Figure 4 ). A procoagulant state in COVID-19 is the result of a direct viral-related endothelial injury, leukocyte-and cytokinemediated platelet activation, TF release, and NETosis augmented by an unchecked activation of the complement system. ./cache/cord-263457-puf8gjir.txt ./txt/cord-263457-puf8gjir.txt
