Abstract:
Diabetic wounds are a serious healthcare concern, affecting approximately 25% of individuals with diabetes globally. Their healing process is often delayed by chronic hyperglycemia, oxidative stress, and persistent inflammation, all of which disrupt normal tissue repair. This review explores the molecular signaling pathways involved in diabetic wound healing and discusses emerging therapeutic strategies targeting these pathways. Key signaling routes such as Wnt/β-catenin, MAPK/ERK, NF-κB/NLRP3, Hippo-YAP, HIF-1α/VEGF-SDF-1α, AKT/eNOS, PI3K/Akt, Nrf2, TGF-β/Smad, and Notch are analyzed for their roles in cell growth, new blood vessel formation, inflammation reduction, and extracellular matrix remodeling. Diabetes disrupts these pathways through advanced glycation end-products, reactive oxygen species, and persistent inflammation, which impair keratinocyte migration, decrease angiogenesis, and prolong inflammation. Recently, promising therapeutic strategies have included nanoparticle-based pathway activation, exosome therapies, and bioactive compounds. Given the extensive interactions among these signaling pathways, therapeutic approaches should target multiple pathways rather than individual signaling components. Future therapeutic strategies may increasingly emphasize personalized medicine, leveraging AI-assisted diagnostics and customised combination therapies to improve management of chronic diabetic wounds.
Insights
Diabetic wound healing is impaired by hyperglycemia and inflammation disrupting key molecular pathways. Emerging therapies focus on targeting multiple pathways for improved chronic wound management.
Area of Science:
- Biomedical Science
- Molecular Biology
- Wound Healing Research
Background:
- Diabetic wounds affect 25% of diabetics globally, with delayed healing due to hyperglycemia, oxidative stress, and inflammation.
- These factors disrupt essential tissue repair processes, leading to chronic non-healing wounds.
Purpose of the Study:
- To review molecular signaling pathways critical for diabetic wound healing.
- To discuss novel therapeutic strategies targeting these pathways for improved patient outcomes.
Main Methods:
- Analysis of key signaling pathways including Wnt/β-catenin, MAPK/ERK, NF-κB/NLRP3, Hippo-YAP, HIF-1α/VEGF-SDF-1α, AKT/eNOS, PI3K/Akt, Nrf2, TGF-β/Smad, and Notch.
- Examination of how diabetes-associated factors (AGEs, ROS, inflammation) disrupt these pathways.
- Review of emerging therapies such as nanoparticle-based treatments, exosome therapies, and bioactive compounds.
Main Results:
- Diabetes disrupts multiple signaling pathways, impairing keratinocyte migration, angiogenesis, and extracellular matrix remodeling.
- These pathways regulate crucial aspects of healing: cell growth, blood vessel formation, inflammation control, and tissue repair.
- Emerging therapies show promise by targeting these disrupted pathways.
Conclusions:
- Therapeutic strategies should target multiple interacting pathways for effective diabetic wound management, rather than single components.
- Future approaches may involve personalized medicine, AI diagnostics, and combination therapies for chronic diabetic wounds.
