This review presents an analysis of scientific publications in recent years devoted to the study of cellular and molecular mechanisms of neutrophilic airway inflammation as potential therapeutic targets in the treatment of severe, poorly controlled asthma of the neutrophil phenotype, the presence of which is still debated and there is no generally accepted definition. The conditional term "neutrophilic asthma" implies the existence of a certain asthma endotype, in which neutrophils are the main type of cells mediating the pathophysiology and disease symptoms. The involvement of the inverted protein response associated with endoplasmic reticulum (ER) stress and the sensory signal transduction protein in the endoplasmic reticulum membrane in the deregulation of the T helper 17 (Th17) cells function and neutrophilic airway inflammation is considered. Polarization and activation of M1 macrophages play an important role in the neutrophilic inflammation immunopathogenesis, in particular, in asthma associated with obesity. Soluble suppression of tumorigenicity 2 protein is considered as a receptor that promotes neutrophil activation and neutrophilic inflammation. The involvement of neutrophil extracellular traps and the respiratory tract microbiome in the neutrophilic inflammation progression, in particular, the role of bacterial outer membrane vesicles, is discussed.
Keywords: neutrophils, neutrophilic inflammation, asthma, Th17 cells, M1 macrophages, suppression of tumorigenicity 2 protein, neutrophil extracellular traps, respiratory tract microbiome.
