Abstract

Chronic lung diseases, such as chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, obstructive sleep apnea, asthma, bronchiectasis, and lung cancer, are intricately linked to the aging process. These diseases are characterized by a high prevalence rate and a paucity of effective treatment options. Emerging evidence highlights the critical role of extracellular vesicles (EVs) in the pathogenesis and progression of these diseases. EVs, released by senescent cells, mediate intercellular communication and modulate immune responses through their cargo of microRNAs, proteins, and other molecules. These vesicles contribute to disease progression by promoting inflammation, fibrosis, tissue remodeling, and cellular senescence. Specifically, certain microRNAs, such as miR-21, miR-34a, and miR-570-3p, along with several proteins in EVs, have been identified as key factors influencing these processes. Additionally, EVs play significant roles in immune regulation and have potential anti-inflammatory effects, making them promising candidates for therapeutic applications. Recent advances in the use of EVs as therapeutic agents, including their application in nanotechnology for targeted drug delivery, have demonstrated potential in reducing inflammation, modulating immune responses, and enhancing tissue repair. Understanding the role of EVs in these diseases offers insights into potential therapeutic targets to mitigate disease progression and improve patient outcomes. Future research should focus on standardizing EV isolation and characterization methods, verifying the safety and efficacy of EV-based therapies in clinical trials, and elucidating the complex biological mechanisms of EVs in aging and disease.
