With increasing cytokine concentrations, especially inflammatory cytokines, a devastating response can negatively affect the respiratory system. Which are usually characterized by inflammatory cell infiltration, cytokine release, epithelial cell damage, airway remodeling, and pulmonary tissue fibrosis.ĭysregulation of the inflammatory response in the respiratory system, which is a significant cause of these diseases, is mediated by a complex intercellular interaction with concentration‐dependent regulation of various cytokines (especially inflammatory factors). Respiratory inflammatory diseases include idiopathic pulmonary fibrosis (IPF), acute respiratory distress syndrome (ARDS), chronic obstructive pulmonary disease (COPD), and asthma, However, owing to air pollution, smoking, population aging, and other factors, the incidence rate of respiratory diseases, especially respiratory inflammatory diseases, has increased, imposing a great financial burden on both national healthcare systems and citizens. The respiratory system plays a significant role in gas exchange, immune function, metabolism, and endocrine functions.
