KPV

KPV – Targeted Anti‑Inflammatory Tripeptide for Gut, Skin, and Repair Research

KPV (L‑Lys‑Pro‑Val) is a short peptide fragment derived from the C‑terminal end of alpha‑melanocyte‑stimulating hormone (α‑MSH) that retains potent anti‑inflammatory and immunomodulatory actions without hormonal melanocortin effects. This selective tripeptide is widely used in research on inflammatory bowel disease, epithelial barrier function, dermatologic inflammation, wound healing, and systemic inflammation models.

Key features

• Potent NF‑κB pathway modulation: KPV suppresses NF‑κB and MAP‑kinase–driven inflammatory signaling, reducing production of key pro‑inflammatory cytokines including TNF‑α, IL‑1β, and IL‑6 in immune and epithelial cells.

• Gut and barrier support: In DSS and TNBS colitis models, orally or systemically administered KPV reduces weight loss, myeloperoxidase activity, histologic inflammation, and cytokine expression while preserving the intestinal barrier and mucosal integrity.

• Skin and wound‑healing activity: Topical KPV accelerates wound closure, decreases erythema, and improves re‑epithelialization in skin and corneal injury models, likely via MC1R signaling, nitric‑oxide modulation, and local immune regulation.

• Antimicrobial and immunomodulatory effects: In vitro studies show KPV can inhibit growth of pathogens such as Staphylococcus aureus and Candida albicans while enhancing neutrophil‑mediated clearance, supporting a combined antimicrobial and anti‑inflammatory profile.

  
  

Research applications

KPV is utilized in experimental systems investigating:

• Gastrointestinal inflammation and IBD, including models of colitis, “leaky gut,” and barrier dysfunction where outcomes include cytokine profiles, histology, permeability, and microbiome‑related endpoints.

• Dermatology and wound repair, such as psoriasis, eczema, atopic dermatitis, post‑procedure healing, and corneal injury, tracking re‑epithelialization, scar quality, and symptom scores.

• Systemic and neuro‑inflammation, exploring KPV’s effects on oxidative stress, neuropathic pain, and inflammatory cascades in CNS and peripheral tissues.

• Recovery and performance contexts, where researchers assess whether dampening chronic low‑grade inflammation improves recovery dynamics and tissue resilience after mechanical or metabolic stress.

  
  

Recommended handling

• For controlled laboratory research use only, by qualified professionals.

• Store in a cool, dry environment away from light; follow institutional SOPs for peptide storage, reconstitution, aliquoting, and disposal.

• Investigators should consult current literature when selecting route (oral, topical, systemic), dosing, and inflammatory or barrier‑function endpoints relevant to their model.
