New evidence for how blood clots may form in very ill COVID-19 patients

(Cold Spring Harbor Laboratory) Neutrophil Extracellular Traps (NETs) have been implicated in causing excessive clotting in cancer patients. In this study, researchers show that the amount of NETs correlates with the severity of disease in COVID-19 patients. They also found that lungs of some deceased COVID-19 patients were dotted with micro-clots of NET-producing cells and platelets.
