Therapeutic targets in COVID‐19 coagulopathy: 616.08.035:616.151.511

Abstract

Summary. Virus-induced coagulopathy is a typical example of the tight connection between inflammation and thrombosis. These two reactions are linked by pro-inflammatory agents, generated by activated neutrophils and their neutrophil extracellular traps (NETs). Extracellular membrane nanobubbles (EMNs), formed by a wide variety of cell types, have recently been identified as new entrants that play a key role in coagulopathy. EMNs directly and indirectly activate coagulation systems that lead to the further upregulation of inflammation and life-threatening organ dysfunction and thrombosis. EMNs are known to be responsible for the secretion, exchange, and transmission of important active biomolecules in COVID-19. Indeed, EMNs represent an essential mech- anism in intercellular communication, and the roles of EMNs in infection and thrombosis have been increasingly recognized. The extracellular microvesicles of viruses, virosomes, represent a new type of infectious agents, which determines new therapeutic goals in solving the problems of controlling viral infections. Understanding the biological nature of all these microvesicles when studying them in vivo is of paramount importance for the development of diagnostic and therapeutic methods.
