IL5 and asthma: To delineate the transcriptomic mechanisms by which IL-5 drives pro-fibrotic reprogramming in asthma, we performed RNA sequencing on IL-5-stimulated lung fibroblasts from asthmatic and healthy donors, coupled with Gene Set Enrichment Analysis (GSEA), to identify dysregulated pathways underlying fibroblast activation and extracellular matrix remodelling (GSE285468).
