KPV

KPV Peptide — Alpha-MSH-Derived Research Peptide

KPV, also known as α-MSH(11–13), is a three-amino-acid peptide derived from the C-terminal sequence of alpha-melanocyte-stimulating hormone (α-MSH). KPV has attracted scientific interest because of its effects in experimental models investigating inflammatory signaling, epithelial biology, intestinal inflammation, and immune responses.

Pure Axis Peptides offers KPV as a research-use peptide for qualified laboratory and scientific investigations.

What Is KPV?

KPV is the C-terminal tripeptide sequence of α-MSH, consisting of lysine-proline-valine. Research has investigated whether this short peptide retains some of the biological properties associated with α-MSH, particularly its effects on inflammatory signaling.

Unlike the larger α-MSH molecule, KPV is a very small tripeptide. Experimental studies have investigated mechanisms that are independent of the classical melanocortin receptor pathway, including peptide transport through PepT1 in intestinal epithelial and immune cells.

KPV Peptide Research

KPV has been investigated across several areas of laboratory research, including:

• Inflammatory signaling
• NF-κB pathway research
• Intestinal epithelial biology
• Gut inflammation research
• Immune-cell signaling
• Skin and epithelial research
• Cytokine signaling
• PepT1-mediated peptide transport
• α-MSH and melanocortin biology
• Cellular stress and inflammatory responses

In experimental intestinal models, researchers have reported that KPV can reduce activation of NF-κB and MAPK signaling pathways and decrease pro-inflammatory cytokine signaling. These findings have been observed in cell-based experiments and animal models and should not be interpreted as evidence of established clinical efficacy in humans.

KPV and NF-κB Signaling

One of the most researched aspects of KPV is its relationship with NF-κB, a transcription factor involved in regulating numerous inflammatory and immune-response genes.

Experimental research in intestinal epithelial cells found that KPV reduced NF-κB activation and inflammatory signaling. Researchers also identified PepT1-mediated uptake as an important component of KPV activity in intestinal epithelial and immune-cell models.

Additional research in human bronchial epithelial-cell models has investigated KPV’s effects on NF-κB signaling, p65 nuclear translocation, and inflammatory chemokine production.

KPV and Intestinal Research

KPV has received particular attention in experimental research involving the gastrointestinal tract.

In mouse models of chemically induced colitis, researchers investigated KPV in relation to inflammatory changes, histological outcomes, and inflammatory markers. These studies provide useful preclinical information about KPV’s potential role as a research tool for studying intestinal inflammatory pathways.

The underlying mechanism is of particular interest because KPV has been reported to enter intestinal epithelial and immune cells through PepT1, rather than relying exclusively on classical melanocortin receptors.

KPV and Skin & Epithelial Research

Because KPV is derived from α-MSH, researchers have also investigated its potential role in epithelial and immune signaling.

Research involving α-MSH-derived peptides has examined NF-κB activation, cytokine expression, immune-cell behavior, and inflammatory signaling in different cell types. KPV has therefore become a useful experimental peptide for investigating the molecular relationship between short melanocortin-derived sequences and inflammatory pathways.
