Know your compound
KPV is a tiny three-part peptide (lysine-proline-valine) snipped from the tail of alpha-MSH, a natural anti-inflammatory hormone. Researchers study it for how it quiets inflammation in gut and skin tissue.
What caught attention: in colitis-model studies, KPV eased inflammation without switching off the immune system — a different route than steroids or standard anti-inflammatory drugs. It also slips into cells through a nutrient transporter called PepT1, which packs it right into inflamed gut lining where it's needed.

The research
The published findings behind this compound — the headline numbers, in plain terms, each cited to source. Preclinical results are directional (animal / in-vitro) and shown for context, not as therapeutic claims.
In a colitis mouse model, KPV loaded into colon-targeted nanoparticles reduced inflammation in the gut lining compared with untreated animals.
DSS-induced colitis mouse model; magnitudes illustrate direction, not exact values.
KPV was shown to enter intestinal lining cells through PepT1 — a nutrient transporter — which delivered it directly into inflamed tissue and dampened the local inflammatory response.
Intestinal epithelial cells and mouse colitis model; relative heights show direction.
In immune-cell research, alpha-MSH-derived peptides including KPV were associated with turning down pro-inflammatory cytokine signalling.
Review of immune-cell studies; directional finding, not a measured percentage.
Mechanism
An α-MSH-derived research peptide studied for calming inflammation with a targeted route into cells.
Studied in colitis models for easing inflammation without switching off the immune system.
Investigated for entering cells through the PepT1 nutrient transporter, concentrating in inflamed gut lining.
Researched for dampening the inflammatory signals that drive intestinal disease models.
