Key peptide (KPV) is a short synthetic tripeptide composed of the amino acids lysine, proline and valine. It has attracted scientific interest because it can modulate inflammation, support immune function and accelerate wound healing. In this review we describe its benefits, possible side effects, recommended dosage and mechanisms of action, summarize the underlying science, and distinguish between research-grade and pharmaceutical-grade preparations.
Benefits
The most widely reported benefit of KPV is its anti-inflammatory activity. Studies in animal models show that a single oral dose can reduce levels of pro-inflammatory cytokines such as tumor necrosis factor alpha and interleukin 6. The peptide also appears to dampen the activation of the NF-kB pathway, which plays a central role in chronic inflammatory conditions.
In addition to anti-inflammation, KPV has been shown to enhance innate immune defenses. Experiments with human skin cells demonstrate that KPV stimulates the production of antimicrobial peptides such as cathelicidin and defensins. This boosts local resistance against bacterial colonisation, an important factor in preventing infections in wounds or ulcers.
KPV’s wound-healing properties are well documented. In murine excisional wound models, topical application accelerates closure by promoting re-epithelialisation and increasing collagen deposition. Histological analysis reveals a higher density of fibroblasts and more organised extracellular matrix compared with untreated controls. The peptide also reduces scar tissue formation, which may be advantageous for patients who require cosmetically acceptable outcomes.
Side effects
Because KPV is a very small peptide it is generally well tolerated. Most human trials report no adverse events at doses up to 100 mg per day. Minor local irritation has been noted when the peptide is applied topically in high concentrations
