Metabolic reprogramming in skin wound healing

Area of Science:

• Biochemistry
• Cell Biology
• Dermatology

Background:

• Metabolic reprogramming allows cells to adapt to stress and gain new functions.
• Skin wound healing relies on metabolic adjustments in nutrients like glucose, lipids, and amino acids.
• Existing literature lacks comprehensive reviews on metabolic reprogramming's role in skin wound healing.

Purpose of the Study:

• To systematically review the metabolic reprogramming of glucose, lipids, and amino acids in skin wound healing.
• To identify therapeutic targets within these metabolic pathways.
• To elucidate the mechanisms of action for metabolic reprogramming in wound repair.

Main Methods:

• Systematic literature review.
• Analysis of metabolic pathways involved in skin wound healing.
• Identification of key enzymes, transporters, and metabolites.

Main Results:

• Glucose metabolism reprogramming influences oxidative stress and inflammation, promoting healing.
• Lipid metabolism reprogramming impacts fibroblast and macrophage populations, enhancing neovascularization and reducing scarring.
• Amino acid metabolism reprogramming is vital for re-epithelialization, collagen deposition, and angiogenesis.

Conclusions:

• Metabolic reprogramming of glucose, lipids, and amino acids plays a multifaceted role in skin wound healing.
• Specific metabolic targets show therapeutic potential for accelerating healing and minimizing scar formation.
• Understanding these mechanisms can guide the development of novel wound care strategies.
