What LL-37 Is Studied For
LL-37 is a naturally occurring 37-amino-acid peptide and part of the body’s first-line immune defense. Research has examined its antimicrobial activity, its role in regulating inflammation, and its involvement in wound healing, including wounds that are slow to close. It is a research peptide, prescription-only.
First-line antimicrobial defense
Regulation of the inflammatory response
Wound healing, including stubborn or chronic wounds
What Is LL-37?
LL-37 is a peptide the human body produces naturally, thirty-seven amino acids long, and it belongs to a family called cathelicidins that form part of the innate immune system, the body’s built-in first line of defense. Its studied roles include disrupting bacterial cell membranes, helping regulate the inflammatory response, and supporting wound healing. Because it is part of the body’s own defenses, researchers have looked at it in the context of chronic wounds and infections that are slow to heal. Most of that work is laboratory and early-stage rather than large human trials. It is not approved by the FDA for any use.
