Contexte de recherche
Profil de recherche GHK-Cu
GHK-Cu is the copper complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine. It is studied in dermal, extracellular-matrix, wound, and cell-signaling models involving copper transport, collagen and elastin markers, fibroblast behavior, tissue remodeling, and gene-expression changes. Experimental outcomes can depend on copper loading, formulation, concentration, cell type, and delivery system, so literature on a finished topical formulation is not automatically comparable with isolated research material. GHK-Cu is most useful when a project specifically requires a copper-binding peptide reference rather than a general repair peptide. Product identity, copper complex status, amount, and batch documentation should be reviewed together.
Molecular class
Copper-binding tripeptide complex
Sequence / composition
- G
- H
- K
Defined amino-acid chain, shown in standard one-letter notation.
Research design note
Copper coordination, oxidation state, free copper, and formulation strongly influence the experimental system.
Mécanisme proposé
GHK binds copper(II), forming a copper-peptide complex proposed to influence copper delivery, gene expression, extracellular-matrix remodeling, antioxidant enzymes, inflammatory signaling, and activity of fibroblasts and other repair-associated cells.
Effets rapportés dans les études
- Cell and animal studies reported increased collagen, elastin, glycosaminoglycan, fibroblast activity, angiogenesis, and wound closure in selected models.
- Topical formulation studies reported changes in skin density, appearance, or fine-line measurements under formulation-specific conditions.
- Effects depend on copper complexation, concentration, formulation, penetration, cell type, and the biological model.
Critères de recherche courants
Copper binding, collagen and elastin synthesis, matrix metalloproteinases, fibroblast migration, antioxidant markers, inflammatory cytokines, wound closure, skin imaging, and histology.
Preuves et limites
Mechanistic and preclinical evidence is substantial, with some formulation-specific human cosmetic data. Results from finished formulations do not establish effects of isolated powder.
