KPV Peptide
Kpv Effects (ACTH(11-13), alpha-MSH)
KPV is the C-terminal peptide fragment of alpha-melanocyte stimulating hormone (alpha-MSH). It is one of many short peptide derivatives of alpha-MSH that has been tested to determine if they retain similar photoprotective properties, activity against ischemia, sexual effects, or benefits on feeding behavior and energy homeostasis. KPV, which is made up of lysine-proline-valine turns out to have significant anti-inflammatory effects. The peptide is under active research as a potential therapeutic in the treatment of inflammatory bowel disease. It has shown evidence of potent anti-inflammatory activity in the central nervous system, GI tract, lungs, vascular system, and joints. Because KPV is a small peptide, it can be administered in multiple ways including oral, intravenous, and transdermal routes.

KPV Peptide Research
Intestinal Inflammation
Perhaps the most important discovery to arise from KPV research is the finding that the peptide reduces intestinal inflammation. In mouse models of inflammatory bowel disease (IBD), KPV shows robust results, reducing inflammatory infiltrates, MPO activity, and overall histological evidence of inflammation. Mice treated with KPV in the study recovered faster and had more pronounced weight gain than mice treated with placebo.
Further research on delivery mechanisms for KPVÂ peptide has revealed that loading KPV onto nanoparticles functionalized with hyaluronic acid helps to direct the inflammatory effects of the peptide to proper locations within the intestine. This leads to accelerated mucosal healing and alleviation of inflammation via a strong down regulation of TNF-alpha in mouse models.
In many ways, KPV is a more effective and more targeted means of reducing inflammation in IBD without affecting TNF-alpha in other locations in the body. The benefit of modifying KPV is in improving the peptide’s oral bioavailability. This does not increase the efficacy of the peptide, but does have an impact on potency and thus total dose require to achieve an effect.
