Although advances have been made in elucidating the pathogenesis of RA-ILD, the specific roles of bile acids remain underexplored. Bile acids are known to modulate immune responses, potentially influencing the inflammatory processes central to RA-ILD; however, their exact mechanisms and therapeutic utility remain unclear. This review aims to elucidate the diverse functions of bile acids, highlighting their potential as both biomarkers of disease activity and as novel therapeutic agents to mitigate pulmonary inflammation and fibrosis. By exploring the gut–lung axis and the interactions between bile acid metabolism and immune responses, the review seeks to identify new avenues for RA-ILD treatment. It also discusses the emerging role of bile acid-derived exosomes in RA and RA-ILD, emphasizing their promise as vehicles for modulating inflammation. This review highlights the significance of current findings and the need for further studies to validate bile acids and their derivatives as reliable markers and effective therapies. By reviewing available research and identifying critical gaps for future research, this review aims to enhance our understanding of RA-ILD and to support the development of targeted interventions that could markedly improve patient outcomes.Keywords: rheumatoid arthritis, interstitial lung disease, bile acids, pulmonary fibrosis, RA-ILD |
