Research advances of exosome microRNA in pulmonary diseases
Exosomes,as a nano-scale carrier,are one of the most important types of extracellular vesicles.MicroRNA(miRNA)are a class of non-coding RNAs with endogenous regulatory functions found in eukaryotic organisms.Exosome-derived miRNA has broad application prospects in pulmonary diseases.This article reviews that exocrine miRNA can regulate lung diseases through a vari-ety of substances/signal transduction,such as acute lung injury,lung cancer,chronic obstructive pulmonary disease,and COVID-19.This review focuses on the research advances of exosome miRNA in the diagnosis and treatment of the above-mentioned lung diseases.With the deepening of the research on exosome miRNA in lung diseases,more new ideas and methods may be provided for the diagno-sis and treatment of lung diseases in the future.
