LL-37

LL-37 is a naturally occurring antimicrobial peptide with various biological functions.

Overview:

Peptide LL-37: A 37-amino acid peptide derived from the C-terminal region of the human cathelicidin antimicrobial peptide (hCAP18).

Structure: Amphipathic, with both hydrophobic and cationic regions, allowing it to interact with and disrupt microbial membranes.

Function: Exhibits antimicrobial, immunomodulatory, wound-healing, and angiogenic properties.

Benefits:

• Antimicrobial Activity: Effective against a wide range of pathogens, including bacteria, fungi, and viruses.Shows promise in combating antibiotic-resistant bacteria like MRSA (Methicillin-resistant Staphylococcus aureus).

• Immunomodulatory Effects: Regulates the immune response by modulating cytokine production and promoting wound healing. Enhances the clearance of pathogens by immune cells like macrophages and neutrophils.

• Wound Healing: Stimulates the migration and proliferation of keratinocytes, leading to faster wound closure.Promotes angiogenesis, facilitating the formation of new blood vessels in the wound area.

Successful Clinical Studies:

• Wound Healing: Clinical trial demonstrating LL-37's efficacy in promoting wound healing in diabetic foot ulcers.Study showing accelerated healing of burn wounds when treated with LL-37.

• Antimicrobial Activity: In vitro studies confirming LL-37's effectiveness against multidrug-resistant bacteria, including Acinetobacter baumannii and Pseudomonas aeruginosa. Clinical trials evaluating LL-37-based therapies for chronic skin infections caused by bacteria like Staphylococcus aureus.

• Immunomodulation: Research highlighting LL-37's ability to modulate inflammatory responses in conditions such as psoriasis and inflammatory bowel disease. Studies investigating LL-37 as a potential therapeutic agent for autoimmune diseases by regulating immune cell activity.
