Cathelicidin LL-37 (Antimicrobial Peptide LL-37)

Cathelicidin LL-37 Antimicrobial & Wound Repair Peptide

【What It Is】

LL-37 is a natural antimicrobial peptide produced by the human body, primarily found in skin, oral cavity, respiratory tract, and immune cells.

It directly disrupts the outer structure of certain bacteria, reducing their survival and reproduction, while recruiting immune cells to sites of infection or injury.

In short, LL-37 helps the body resist harmful microbes and accelerates the repair of damaged skin and wounds.

【Key Benefits】

· Enhances the body's own antimicrobial capacity

· Inhibits the growth of various harmful bacteria

· Helps resist bacteria, fungi, and some viruses

· Reduces bacterial aggregation on wound surfaces

· Accelerates damaged skin and wound repair

· Improves the recovery environment around infected sites

【Product Features】

· Natural antimicrobial component produced by the human body

· Dual antimicrobial and tissue repair actions

· Directly disrupts the protective structure of certain bacteria

· Recruits immune cells to handle harmful microbes

· Purity: ≥99% (HPLC tested)

【Broad-Spectrum Antimicrobial】

LL-37 contacts and disrupts the outer protective structure of certain bacteria, compromising their integrity and reducing their ability to survive and reproduce.

It exhibits inhibitory effects against a variety of common bacteria and also shows defensive capability against some fungi and viruses.

This broad range of action is more extensive than targeting a single bacterium, but it does not replace prescribed antibiotics or standard anti-infection treatments.

【Reduces Bacterial Biofilm】

Some bacteria aggregate on skin, wounds, or medical device surfaces, forming a protective sticky film.

This biofilm makes bacteria more resilient, harder to eliminate, and slows wound recovery.

LL-37 interferes with bacterial aggregation and reduces biofilm formation, making it easier for the body to handle these harmful bacteria.

【Skin & Wound Repair】

After skin damage, controlling harmful microbes is essential, but new skin cells must also migrate to the injured site for repair.

LL-37 promotes the migration of skin cells to the wound and accelerates the formation of new tissue in the damaged area.

It also improves blood supply around the wound, providing more oxygen and nutrients for skin repair.

【Enhances Body Defense】

When harmful microbes enter the body, immune cells need to locate and address the issue promptly.

LL-37 sends signals to attract immune cells to infection or injury sites, enhancing local defense.

It also neutralizes certain harmful substances released by bacteria, reducing irritation and damage to surrounding tissues.

【Inflammation Modulation】

Normal inflammatory responses help the body clear bacteria and repair damage, but excessive inflammation can also irritate healthy tissue.

LL-37 can modulate the inflammatory response depending on the local environment, aiding the body in completing antimicrobial and repair processes.

Note: LL-37 is not a general anti-inflammatory agent; excessively high levels may exacerbate certain skin inflammations.
