Identification and Immune Cell Profiling of Exosome-related Genes in Acute Respiratory Distress Syndrome: An Integrated Bioinformatics Analysis.

This study first systematically identified EXORDEGs in ARDS, discovering four hub genes and their associations with immune cells. The hub genes may be implicated in endothelial injury, inflammation, and immune dysregulation. These findings provide novel insights into ARDS pathogenesis and highlight potential therapeutic targets for further investigation. Given the disease heterogeneity, our findings primarily reflect common molecular characteristics, while the specific features of different etiological subtypes require further investigation.
