Authors: Luca Perico1†, Marina Morigi1†, Miriam Galbusera1, et. al. Frontiers in Immunology March 2922 Microvascular thrombosis is associated with multiorgan failure and mortality in coronavirus disease 2019 (COVID-19). Although thrombotic complications may be ascribed to the ability of SARS-CoV-2 to infect and replicate in endothelial cells, it has been poorly investigated whether, in the complexity of viral infection in […]
