Abstract
The aim of the study: The immune system, as one of the most sensitive to the action of external and internal factors of functional systems, is involved in all pathological processes occurring in the body. Indicators of the immune system can be used to monitor the patient's condition and predict the development of the disease [1].
Interleukin-17 belongs to pro-inflammatory cytokines and is involved in many stages of the immune response. It stimulates the production of chemokines and, as a result, stimulates the migration of neutrophils to the site of inflammation [2]. IL-17 triggers an extensive tissue reaction leading to the migration of neutrophils to the inflammatory zone. It can be produced by many cells, but the most pronounced production is provided by type 17 T-helper cells (Th17) [3]. The aim of the study was to study the cytokine status in urgent conditions in children with respiratory diseases.
