An ROS-responsive antioxidant hydrogel with immunomodulatory activity for promoting diabetic wound healing

evaluation results show that this hydrogel can effectively alleviate oxidative stress, accelerating cell migration, proliferation, and angiogenesis. Transcriptome sequencing analysis further revealed that its pro-healing effects are mechanistically associated with key signaling pathways, especially PI3K-AKT and PPAR signaling pathways, to facilitate cell proliferation and suppress inflammation. Overall, the hydrogel provides a straightforward but effective platform for chronic diabetic wound healing.
