KPV (Lys–Pro–Val) is a research-use-only tripeptide corresponding to the α-MSH (11–13) fragment. In tissue remodeling and protein-function studies, KPV is used to interrogate epithelial barrier dynamics, fibroblast behavior, and cell–matrix signaling under controlled stress conditions. Models frequently assess cytokine milieu, redox status, and structural readouts relevant to extracellular matrix (ECM) organization. Not intended for diagnostic or therapeutic use.
