　　The reporter recently learned from the Kunming Institute of Zoology, Chinese Academy of Sciences, that a research team in the Laichen laboratory has identified an effective skin repair peptide-tyrosine from red wart skin. The results were published in the Journal of the American Association of Experimental Biology. Well-known amphibians.

　　Like Salamander, it has extraordinary wound repair capabilities, but little is known about its mechanism and the active substances that may promote skin wound repair. Well, researchers have been trying to find active ingredients in sal skin that can promote wound repair and tissue healing, which is essential to understand the rapid skin healing of sal and the development of skin repair agents. The important thing is that now, researchers have identified an effective skin repair peptide tyrosine from the red skin of the new scrotum, which contains only 12 amino acid residues. In the mouse model of full-thickness skin lesions, it has a strong activity to promote wound healing. Tyrosine promotes the proliferation and migration of keratinocytes and fibroblasts, thereby promoting epithelialization and granulation tissue formation in damaged skin. At the same time, the repair peptide can promote the production of TGF-β1 and IL-6, which are closely related to wound healing.
