[Exosomes' role in intercellular interactions in different variants of lung injury in fatal cases of COVID-19].

Background: Extracellular vesicles are surrounded by a phospholipid bilayer, carrying various active biomolecules and participating in many physiological and pathological processes, including infectious ones.

Objective: To research the role of exosomes in intercellular interactions in the pathogenesis of various types of lung damage in fatal cases of COVID-19.

Material And Methods: We conducted a clinical and morphological analysis of 118 fatal cases caused by coronavirus infection in Moscow.
