Antimicrobial research peptides

Antimicrobial peptide research focuses on cationic amphipathic peptides that disrupt anionic microbial membranes while modulating host immune signalling. LL-37 is the principal mammalian example.

Peptides in this category

LL-37

Cathelicidin LL-37 · hCAP-18 fragment

The only human cathelicidin antimicrobial peptide — a 37-residue cationic helix studied for direct antimicrobial action, wound healing, angiogenesis, and modulation of host immune responses.

Relevant comparisons

KPV vs LL-37
KPV and LL-37 occupy overlapping but distinct niches in the inflammation–antimicrobial peptide space. KPV is small, charge-neutral, and primarily anti-inflammatory; LL-37 is larger, cationic, and combines direct antimicrobial activity with broad immunomodulation.
