Robinia pseudoacacia L. Flower Exosome‐Like Nanoparticles (RFELNs) Activate AhR/IL‐22 to Relieve Intestinal Barrier Dysfunction Through Regulating Gut Microbiota‐Interrelated Tryptophan Metabolism in Ulcerative Colitis Mice

Mediators of Inflammation, Volume 2026, Issue 1, 2026.
Background Intestinal barrier dysfunction is a key driver of ulcerative colitis (UC) recurrence and chronic persistence. Modulating group 3 innate lymphoid cells (ILC3) activity and tryptophan‐derived metabolites is crucial for enhancing mucosal repair in UC. Robinia pseudoacacia L. flower exosome‐like nanoparticles (RFELNs) could ameliorate intestinal
