KPV research: studies, doses and safety
An alpha-MSH fragment studied for gut inflammation in animals, with no human dosing trial.
Also called: Lys-Pro-Val, Lysine-proline-valine, alpha-MSH(11-13), KPV acetate.
Anti-inflammatory and antimicrobial peptides · C-terminal alpha-MSH tripeptide with preclinical anti-inflammatory activity · Evidence: Animal studies only.
No human intervention study identified. Six key animal studies are listed; human cell or biopsy work does not establish a human dose.
Key studies
- PepT1 and mouse colitis: KPV entered cells via PepT1 and reduced inflammation in two mouse colitis models. (source)
- Two mouse colitis models: KPV reduced gut inflammation even when MC1R signaling was impaired. (source)
- Rabbit corneal wounds: KPV sped corneal wound closure in rabbits; this is not evidence for human eye use. (source)
- Colitis-associated tumors in mice: KPV reduced tumor formation in wild-type mice, not PepT1-knockout mice. (source)
- Targeted oral KPV particles: A special gut-targeting formulation improved delivery and reduced mouse colitis. (source)
- Inflammation-targeted proKPV: A modified KPV delivery system improved tissue uptake in mice. (source)
