Description
LL-37
LL-37 is a human-derived antimicrobial peptide that strengthens innate immunity, destroys bacterial cell walls, and promotes rapid wound healing. It acts as a natural antibiotic, combating viruses, biofilm-mediated infections, and bacteria while modulating inflammation. Key benefits include accelerated skin repair, chronic infection management, and potential anticancer properties
Key Benefits of LL-37 Peptide
- Potent Antimicrobial Activity:
LL-37 is highly effective against Gram-positive and Gram-negative bacteria by breaking down their cell membranes. - Biofilm Disruption:
It disrupts biofilms (protective layers formed by bacteria), making it effective against stubborn, chronic infections. - Wound Healing and Tissue Repair:
It promotes angiogenesis (new blood vessel formation) and speeds up wound repair. Studies show it is effective in treating chronic, non-healing ulcers. - Immune Modulation:
It regulates the immune system, acting as both a pro-inflammatory agent (to fight infection) and an anti-inflammatory agent (to control excessive inflammation), which is crucial for conditions like atopic dermatitis. - Antiviral Properties:
LL-37 has shown ability to combat viruses, including SARS-CoV-2, by blocking viral entry and reducing inflammatory responses. - Cancer Support:
Research indicates potential, albeit complex, roles in suppressing tumor growth in certain cancers, such as gastric cancer.
Common Therapeutic Applications
- Infections:
Used for antibiotic-resistant bacteria and chronic, lingering infections. - Wound Care:
Applied topically for diabetic ulcers, chronic wounds, and skin infections. - Immune Support:
Used in some integrative medicine approaches to boost immune function and treat viral infections.
