Immune & Inflammatory
LL-37's defining research application — the only human cathelicidin antimicrobial peptide, acting as a first-line immune defense.
Wound healing
Directly kills bacteria at the wound site while simultaneously recruiting immune cells, a dual action distinct from BPC-157's growth-signaling approach.
Anti-inflammatory
Helps regulate inflammation as part of its broader antimicrobial and immune-signaling role, rather than through a dedicated anti-inflammatory pathway.
