This discussion compares tripeptides, exemplified by the well-studied GHK, with larger peptides such as the cyclic heptapeptide CyRL-QN15, the human cathelicidin-derived antimicrobial peptide LL-37, and the peptide Andersonin W-1 (AW1), containing 7, 37, and 72 amino acids, respectively [25, 67, 68]
This copper peptide gene regulation manifests in several clinically significant ways: Downregulation of Pro-Inflammatory Genes: It actively suppresses genes associated with inflammation, such as those in the IL-6 and NF-B pathways, which are major drivers of cellular aging
