Inflammatory memory-activated biomimetic nanovesicles regulate neutrophil plasticity and metabolic reprogramming for rapid diabetic wound healing via targeting miR-193a-5p/TLR4/JNK/P38 MAPK pathways.

ABSTRACT: Diabetic wound therapy faces significant challenges due to the complexity of the wound microenvironment, especially dysregulated immune cell responses and persistent pro-inflammatory sate. Targeting immune cells to reverse pathological wound conditions has increasingly become a promising strategy to promote diabetic wound healing. It has been reported that prolonged memory to acute inflammation sensitizes epidermal stem cells (EpSCs) to tissue damage. The increasing importance of interactions between immune cells and tissue stem cells has raised interest in the potential of EpSCs to induce inflammatory adaptations in diabetic wounds, and meanwhile, the inflammation memory patterns also provide new insight in EpSCs for tissue repair. Here, bioinspired cell-derived mimetic nanovesicles (MNVs
