KPV

Product research information

KPV is a naturally occurring tripeptide fragment with the molecular formula C₁₆H₃₀N₄O₄. It corresponds to the specific amino acid sequence Lys-Pro-Val. This sequence is derived from alpha-Melanocyte Stimulating Hormone (α-MSH), a peptide known for its role in pigmentation and energy homeostasis. However, the KPV fragment is distinct in that it does not bind to the melanocortin receptors responsible for melanogenesis, allowing researchers to study its anti-inflammatory potential in isolation.

Scientific studies focus on KPV’s ability to modulate the NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) signaling pathway. In laboratory models, KPV has been observed to translocate into cells via the PepT1 peptide transporter, where it may downregulate the expression of pro-inflammatory cytokines. This mechanism is of particular interest in research regarding Inflammatory Bowel Disease (IBD) and colitis.

Additionally, KPV is investigated for its antimicrobial activity. Studies suggest that the peptide may disrupt the structural integrity of fungal and bacterial membranes. In dermatological research, KPV is utilized to examine wound healing rates and the reduction of contact dermatitis, promoting the study of peptide-based modulation of the host immune response without the side effects associated with steroidal compounds.
