VWF and COVID-19: We found in situ evidence of platelet- and VWF-rich thrombi in COVID-19 lungs; higher prevalence of characteristic NETosis thrombi with platelet and VWF enrichment in COVID-19 lungs; and overexpression of VWF in pulmonary draining lymph nodes and higher nodal presence of VWF+ histiocytes in COVID-19, which correlates with early death [49].
