Abstract Ulcerative colitis (UC) is a chronic inflammatory bowel disease mainly involving the colon and rectum, which features recurrent mucosal inflammation. The excessive production of reactive oxygen species (ROS) trigger for pathological changes such as cell apoptosis disordered immune microenvironments, are crucial progression UC can be promising therapeutic target. Nowadays, development targeted strategies still in its infancy. Thus, developing effective therapies based on ROS scavenging elucidating their molecular pathways urgently needed. Herein, biomimetic nanoformulation (Pd@M) with cubic palladium (Pd) core macrophage‐derived extracellular vesicles (MEVs) shell synthesized treatment UC. These Pd@M nanoformulations exhibit multienzyme‐like activities scavenging, excellent targeting ability well good biocompatibility. It verified that regulate polarization state macrophages by inhibiting glycolysis, decrease neutrophil infiltration recruitment. In this way, colonic microenvironment remodeled, prevented, ultimately improving barrier function alleviating mouse model. This finding provides alternative option patients.

The artificial mucus layer, such as hydrogels, used to repair the damaged intestinal barrier, is a promising treatment for inflammatory bowel disease (IBD). However, currently reported hydrogel-based barriers are administered via rectal injection, causing unnecessary discomfort patients. Herein, we report an oral hydrogel precursor solution based on thiol-modified hyaluronic acid (HASH). Owing reactive oxygen species (ROS)–responsive gelling behavior, our formed coating over inflamed regions of intestines, blocking microbial invasion and reducing abnormally activated immune responses. Notably, HASH also modulated gut microbiota, including increasing diversity enhancing abundance short-chain fatty acid–associated bacteria, which play key role in homeostasis. We believe that ROS-responsive layer strategy IBD.

Inflammatory bowel disease (IBD) is strongly related to the occurrence of accumulation toxic reactive oxygen species (ROS), inflammation mucosa, and an imbalance intestinal microbes. However, current treatments largely focus on a single factor, yielding unsatisfactory clinical outcomes. Herein, we report biocompatible IBD-targeted metabolic nanoregulator (TMNR) that synergistically regulates cellular bacterial metabolism. The TMNR comprises melanin-gallium complex (MNR) encapsulated within thermosensitive colitis-targeting hydrogel, all composed natural FDA-approved components. confers superior broad-spectrum antioxidant properties, effectively scavenging (ROS) blocking inflammatory signaling pathways. presence Ga3+ in selectively disrupts iron metabolism pathogenic microorganisms due its structural resemblance atom.
