Abstract:
As a result of the stimulation of proinflammatory mediators, circulating peripheral-blood mononuclear cells migrate into the wound area, and they differentiate into different phenotypes of macrophage to take different roles in healing process. Their phenotypes interchange under different microenvironments. The disturbance of cutaneous environment in diabetic patients has been shown to alter the quantity, morphology, and functions of the macrophages resulting in retardation of wound healing. Healing of intractable diabetic wound can be improved by the supplement of exogenous growth factors, which might improve healing process by regulating the phenotype of macrophage in intractable diabetic wound. This article reviews the relationship between intractable diabetic wound and macrophage to explore new methods of treating intractable diabetic wound.
Insights
Diabetic wound healing is impaired by altered macrophage function. Exogenous growth factors may improve healing by regulating macrophage phenotypes in these chronic wounds.
Area of Science:
- Wound healing research
- Immunology
- Diabetic complications
Background:
- Proinflammatory mediators drive peripheral-blood mononuclear cells into wound sites.
- Macrophages exhibit diverse phenotypes crucial for wound healing, adaptable to microenvironmental cues.
- Diabetic cutaneous environments disrupt macrophage quantity, morphology, and function, impeding wound repair.
Purpose of the Study:
- To review the intricate relationship between intractable diabetic wounds and macrophage behavior.
- To explore the potential of exogenous growth factors in modulating macrophage phenotypes for improved diabetic wound healing.
Main Methods:
- Literature review focusing on macrophage biology in wound healing.
- Analysis of studies investigating diabetic wound pathophysiology.
- Examination of research on growth factor supplementation in wound treatment.
Main Results:
- Macrophage phenotype plasticity is central to wound healing dynamics.
- Diabetic conditions significantly alter macrophage roles, leading to delayed healing.
- Exogenous growth factors show promise in normalizing macrophage function.
Conclusions:
- Understanding macrophage dynamics is key to addressing diabetic wound complications.
- Targeting macrophage phenotypes with growth factors represents a potential therapeutic strategy for intractable diabetic wounds.
