Abstract: BACKGROUND: In recent years, with the in-depth study of exosomes, the protein RNA, DNA, miRNA and other molecular substances carried on the surface are closely related to the occurrence, development, and prognosis of chronic respiratory diseases.
OBJECTIVE: Based on the structural and functional characteristics of exosomes, to explore the relationship between exosomes and chronic obstructive pulmonary disease, asthma, interstitial lung disease and lung cancer, and to systematically analyze the effects of exosomes from different cell sources on chronic respiratory diseases.
METHODS: A review of the relevant literature of domestic well-known databases such as CNKI, Wanfang, VIP, CBM and foreign databases such as PubMed, Cochrane Library, and Embase in the past 10 years was reviewed. “Exosomes” and “respiratory diseases” were search terms in English and Chinese, and the search time was from the establishment of the database to May 2020. Relevant articles related to the treatment of respiratory diseases with exosomes were included.  
RESULTS AND CONCLUSION: Exosomes carry a variety of active substances such as protein and RNA, and are widely involved in the information exchange between cells and tissues. Exosomes maintain the physiological functions of the active substances by virtue of their small diameter and difficulty in being swallowed, and exert many functions such as intercellular information transmission, immune regulation, inflammatory response and signal transduction, and have become potential targets for regulating the development of respiratory diseases. Exosomes improve the function of receptor cells, protect damaged tissues, and participate extensively in cellular inflammatory and immune response processes through their information transmission channels. They are expected to provide new treatment methods for the diagnosis and prevention of chronic respiratory diseases.

Key words: exosomes, respiratory diseases, chronic obstructive pulmonary disease, asthma, interstitial lung disease, lung cancer, review
