Core Tip

Core Tip: Nonhealing diabetic foot ulcers (DFUs) are a debilitating condition with the risk of amputation despite the advanced treatment strategies. Chronic inflammation, decreased granulation tissue formation, and decreased angiogenesis underlies the pathogenesis of nonhealing. Targeted delivery of therapeutics targeting immune cell infiltration and chronic inflammation with loaded exosomes may increase the efficacy of treatment. We herein discuss the potential of exosomes loaded with resolvins and drugs targeting inflammatory cytokines to promote DFUs healing.
