Research Comparison
KPV (Lys-Pro-Val) vs LL-37 (Human Cathelicidin)
A side-by-side research comparison of KPV (Lys-Pro-Val) and LL-37 (Human Cathelicidin) drawn from Cobalt Peptides' peptide database records.
KPV (Lys-Pro-Val)
KPV (Lys-Pro-Val) is a tripeptide derived from the C-terminal fragment of alpha-melanocyte-stimulating hormone (α-MSH). Unlike the parent hormone, KPV retains potent anti-inflammatory and immunomodulatory activity without inducing melanogenesis or pigmentation. It has been investigated for its ability to modulate inflammatory pathways at the cellular level, with particular relevance to inflammatory bowel disease, dermatological conditions, and systemic inflammation. Its small size enables efficient cellular penetration and direct interaction with intracellular signaling pathways.
LL-37 (Human Cathelicidin)
LL-37 is the only known human cathelicidin antimicrobial peptide, consisting of 37 amino acids and derived from the precursor protein hCAP18. It plays a critical role in innate immunity, exhibiting broad-spectrum antimicrobial activity against bacteria, viruses, and fungi while also modulating inflammatory responses and promoting tissue repair. It is most commonly studied in topical applications for wound healing, where it provides both antimicrobial protection and regenerative support. Clinical and experimental data show significant improvements in chronic wound healing, though systemic use remains less well characterized.
