KPV peptide (Lys-Pro-Val) is a tripeptide fragment derived from α-melanocyte-stimulating hormone, prized in research for its cell-level anti-inflammatory and tissue-repair actions. In controlled lab settings—covering macrophage, keratinocyte, endothelial, and neural-glial models—KPV probes how cytokines, cell migration, and barrier function interact during inflammation and healing.
