Edible Bird's Nest Peptide- an Active Peptide With Potential in Promoting Skin Repair

Area of Science:

• Biochemistry
• Dermatology
• Regenerative Medicine

Background:

• Skin aging and damage result from UV radiation and pollution.
• Edible bird's nest peptide (EBNP) offers antioxidant and anti-inflammatory properties for skin protection.

Purpose of the Study:

• To investigate the pro-tissue regeneration effects of EBNP.
• To elucidate the mechanisms underlying EBNP-mediated skin repair.

Main Methods:

• Assessed EBNP's impact on wound healing in cellular models and zebrafish larvae.
• Analyzed gene expression related to structural proteins and extracellular matrix (ECM) components.
• Evaluated EBNP's anti-inflammatory effects by measuring nitric oxide (NO), reactive oxygen species (ROS), inflammatory cytokines (IL-1, IL-6, TNF-α), and neutrophil counts.

Main Results:

• EBNP contains epidermal growth factor (EGF) and stimulates wound healing.
• EBNP up-regulates COL1A1 gene expression in cells and col1a1b, eln1, eln2 genes in zebrafish larvae, enhancing ECM remodeling.
• EBNP reduces NO and ROS production, lowers IL-1, IL-6, and TNF-α levels, and decreases neutrophil count, indicating anti-inflammatory action.

Conclusions:

• EBNP accelerates wound healing via anti-inflammatory mechanisms and EGF-like activity.
• EBNP promotes tissue regeneration by enhancing ECM remodeling and collagen/elastin synthesis.
• EBNP shows potential for applications in food, medicine, and cosmetics for skin repair.
