KPV is a potent, three-amino-acid peptide fragment derived from Alpha-Melanocyte-Stimulating Hormone (α-MSH). It isolates the molecule’s strong immune-modulating and anti-inflammatory properties without triggering skin pigmentation. In laboratory models, KPV enters cells to deactivate the NF-κB pathway, significantly reducing pro-inflammatory cytokine cascades. It is widely utilized to study wound healing, intestinal barrier recovery and cellular inflammatory stress.
