The nervous system and the immune system are relatively independent but interactional, and neuro-immune regulation is very important for the respiratory system to resist external harmful stimuli and to maintain homeostasis. Neuro-immune interaction is involved in the occurrence and development of respiratory diseases, and is essential for monitoring and modulating inflammation and tissue repair. This article summaries the neuro-immune regulation of respiratory system and discusses its role in respiratory diseases, aiming to provide a theoretical basis for further understanding the crosstalk between the nervous and immune systems, to explore the underlying mechanism in respiratory diseases, and to provide new thoughts for the prevention and treatment of respiratory diseases.
