Acid-responsive CST@NPs enhanced diabetic wound healing through rescuing mitochondrial dysfunction.

ABSTRACT: Diabetic ulcers (DUs) are persistent and challenging complications of diabetes. The consequences of DUs include a decline in functional status, increased risk of infection, hospitalization, and even death. Our study revealed a significant decrease in the levels of cortistatin (CST) in the skin tissue of patients with DUs and diabetic rats. This finding led us to hypothesize that the administration of exogenous CST is an effective strategy to promote wound healing in patients with DUs. We herein successfully prepared CST-loaded pDMA-pEPEMA nanoparticles (CST@NPs) designed to exhibit localized, acid-responsive behavior for enhanced wound healing. These CST@NPs were sensitive to acidic environments, triggering the rapid release of CST. In vitro experiments showed that CST@NPs effective
