The Dossier
Research Notes
KPV is a naturally occurring tripeptide corresponding to the C-terminal fragment (residues 11–13) of alpha-melanocyte-stimulating hormone. It retains the anti-inflammatory character of the parent hormone while lacking its pigment-inducing activity — the compact 'active message sequence' first characterized in 1989.
It is a compact reference standard in the recovery category, studied for its signaling role in models of cellular inflammation response.
Research Focus
- ✦Inflammatory-bowel and colitis models
- ✦Dermatological-inflammation models
- ✦Corneal and cutaneous wound-healing models
- ✦Antimicrobial-activity research
- ✦Joint- and pulmonary-inflammation models
Mechanism
Unlike alpha-MSH, KPV is characterized as not binding melanocortin receptors; instead it enters cells via the PepT1 peptide transporter, which is upregulated in inflamed tissue.
Once internalized it is reported to bind Importin-α3 to block nuclear import of NF-κB and to stabilize IκBα — a dual anti-inflammatory action — alongside inhibition of ERK, JNK, and p38 MAPK signaling.
