research Hypoxia macrophage-derived exosomal miR-26b-5p targeting PTEN promotes the development of keloids
The researchers reported that exosomes from hypoxic M2 macrophages, enriched with miR-26b-5p, promoted proliferation, migration, and invasion in human keloid fibroblasts through the PTEN-PI3K/AKT pathway, highlighting miR-26b-5p's role in keloid development.
