Eosinophil extracellular traps: their  role in health and disease
Vitebsk State Order of Peoples’ Friendship Medical University, Vitebsk, Republic of Belarus

Vestnik VGMU. 2019;18(5):26-34.

The review presents the current data about a new mechanism of antimicrobial action of eosinophilic granulocytes – the formation of eosinophil extracellular traps (EETs). The extraction of extracellular DNA traps was also detected in neutrophils, mast cells, monocytes, tissue macrophages and lymphocytes. The formation of extracellular traps, apart from  humans, was observed in fish, bull, horse, cat, mouse and hen. The death of eosinophils with the release of extracellular DNA traps is called «EETosis». The main structural components of eosinophil extracellular traps, factors stimulating their appearance and mechanisms of the antimicrobial action of eosinophil extracellular  DNA traps are described in the article. The main  infectious, inflammatory and allergic diseases , in which EETs formation was observed, are presented in this review. The study of new immunological mechanisms of the human body  defense, such as the formation of extracellular traps by  various immune system cells, appears to be of great interest not only for scientists, but also for practicing physicians.
Key words: eosinophils, eosinophil extracellular traps, EETosis, DNA.
