KPV is a naturally derived tripeptide composed of lysine, proline, and valine. It is most commonly described as the C-terminal fragment of alpha-melanocyte-stimulating hormone (alpha-MSH), a larger peptide associated with immune and inflammatory signaling. KPV is studied because it appears to preserve many of the anti-inflammatory properties of alpha-MSH while lacking the pigment-inducing activity associated with the larger melanocortin system.
The scientific interest around KPV is strongest in inflammation, epithelial barrier, gut, skin, and immune-modulation research. In intestinal models, KPV has been studied in relation to PepT1-mediated uptake, reduced inflammatory signaling, and colitis-associated inflammation. In skin and wound-related research, alpha-MSH-related peptides such as KPV are studied for their ability to influence inflammatory pathways without directly functioning as traditional growth-factor peptides. KPV has also been investigated for antimicrobial-response activity against organisms such as Staphylococcus aureus and Candida albicans in laboratory models.
