Advances in rationally engineered cytokines for precision therapy in diabetic wound healing
Abstract
Diabetic wound healing presents a unique and complex challenge due to the impaired cellular and molecular functions associated with diabetes. Chronic wounds in diabetic patients are characterized by prolonged inflammation, reduced angiogenesis, and impaired collagen deposition, which significantly hinder the healing process. This comprehensive review focuses on the innovative applications of designer cytokines in precision therapy for diabetic wound healing, emphasizing the remarkable advancements made in overcoming the limitations of natural cytokines, such as their short half-life, potential cytotoxicity, and lack of specificity. We begin by detailing the intricate biological characteristics of diabetic wounds and the essential role that cytokines play in orchestrating the healing process. The review critically examines the constraints of natural cytokines and traces the evolution of synthetic alternatives, with a particular emphasis on peptide-based and nucleic acid-based artificial cytokines. Advanced strategies for designing these artificial cytokines are discussed, including molecular modifications, functional enhancements, and specificity improvements to better target pathological conditions in diabetic wounds. Furthermore, we explore the utilization of synthetic biology techniques to engineer effective cytokine-based therapies. The promising therapeutic potential of rationally designed cytokines is highlighted, showcasing their ability to modulate the wound microenvironment, enhance tissue regeneration, and reduce chronic inflammation. This review not only provides valuable perspectives on the future research directions but also offers insights into the potential clinical applications of these innovative therapies, aiming to significantly improve the outcomes for patients suffering from diabetic wounds.
