Detailed Explanation
Bioactive peptide fragment released from extracellular matrix (ECM) proteins during tissue remodeling, injury, or aging. Matrikines are produced when proteases (matrix metalloproteinases, elastases) degrade structural proteins like collagen, elastin, and fibronectin. The released peptide fragments act as signaling molecules, recruiting immune cells, stimulating fibroblast proliferation, promoting angiogenesis, and triggering further ECM remodeling.
GHK-Cu is a matrikine tripeptide. The elastin-derived VGVAPG peptide is another well-studied example. Matrikines play dual roles: beneficial in wound healing but pathological in chronic diseases like emphysema and atherosclerosis where ongoing ECM degradation perpetuates inflammation.
