What is LL-37 Peptide?
The ll 37 peptide is the only known member of the cathelicidin family of antimicrobial peptides found in humans. This ll 37 peptide is a cationic, amphipathic peptide with a characteristic α-helical structure that allows it to interact with and disrupt microbial cell membranes. The ll 37 peptide is produced by various cell types, including neutrophils, epithelial cells, and macrophages, and plays a central role in the body’s innate immune defense.
Research on the ll 37 peptide has revealed its diverse functions beyond simple antimicrobial activity, including immunomodulation, wound healing, and even potential roles in cancer biology. When you source ll 37 peptide from Planex Supplies, you are acquiring a compound that is central to understanding human host defense mechanisms.

LL-37 is extensively studied for its ability to neutralize a broad spectrum of pathogens, including bacteria, fungi, and certain viruses. In mucosal immunity research, it is noted for its presence in corneal and conjunctival epithelia, where it provides a protective barrier against ocular infections by disrupting the integrity of pathogen cell membranes.
Beyond its direct antimicrobial properties, LL-37 acts as a potent immunomodulator. Research suggests it helps maintain immunological homeostasis by preventing hyperactive responses during infections. Interestingly, its behavior appears to be context-dependent; for instance, it may stimulate inflammatory action in resting T-cells but minimize such action in activated T-cells.
The peptide’s role in chronic inflammatory conditions is a significant focus of modern clinical research. Studies involving models for rheumatoid arthritis, lupus, psoriasis, and atherosclerosis investigate how LL-37 influences:
-
- Cytokine Production: Modulation of IFN-alpha and IL-18.
- Cell Signaling: Suppression of Toll-Like Receptor 4 (TLR4) signaling.
- Chemotaxis: Influencing the movement of neutrophils and eosinophils to inflammatory sites.
LL-37 has been observed to promote angiogenesis (the formation of new blood vessels) and facilitate the migration of keratinocytes, making it a subject of interest in research related to wound recovery and epithelial repair mechanisms.
LL 37 Peptide Benefits
The ll 37 peptide benefits are wide-ranging and well-documented in scientific literature. When you purchase ll 37 peptide for sale, you gain access to a compound with demonstrated potential in multiple areas of research.
Broad-Spectrum Antimicrobial Activity
One of the primary ll 37 peptide benefits is its potent activity against a wide range of pathogens, including Gram-positive and Gram-negative bacteria, fungi, and viruses. The peptide’s mechanism of action involves disrupting microbial cell membranes through electrostatic interactions and pore formation, which makes it effective against antibiotic-resistant strains. This ll 37 peptide benefit is particularly relevant in studies of chronic infections and biofilm formation, where LL-37 has shown promise in disrupting bacterial biofilms.
Immunomodulatory Effects
Another significant ll 37 peptide benefit is its ability to modulate the immune response. LL-37 can neutralize bacterial endotoxins like lipopolysaccharides (LPS) and regulate the production of cytokines and chemokines, thus influencing both pro-inflammatory and anti-inflammatory pathways. This ll 37 peptide benefit makes it a valuable tool for studying the complex interplay between the immune system and infectious diseases. In research models, LL-37 has been shown to reduce concentrations of pro-inflammatory cytokines while restoring levels of anti-inflammatory ones.
Wound Healing and Tissue Repair
LL-37 has been shown to promote wound healing through its chemotactic and pro-angiogenic activities. It can attract immune cells to sites of infection and injury and stimulate the formation of new blood vessels. A clinical trial focusing on hard-to-heal venous leg ulcers found that topical treatment with LL-37 was safe and well-tolerated, with marked effects on healing predictors. This ll 37 peptide benefit is of particular interest in regenerative medicine and dermatological research.
Potential Role in Cancer Research
The role of LL-37 in cancer is complex and context-dependent, exhibiting both anti-cancer and pro-cancer effects. This ll 37 peptide benefit, or its opposing effect, makes it a subject of intense study for its potential in cancer therapy. Research suggests that LL-37 can directly inhibit the growth of certain cancer cells and modulate the immune response against tumors.
What Does LL 37 Do?
The question what does ll 37 do is central to understanding its importance in research. LL-37 performs multiple functions, acting as a direct antimicrobial agent by disrupting microbial cell membranes and as a crucial immunomodulatory molecule. It also plays a role in angiogenesis, wound healing, and can influence cellular processes such as proliferation and differentiation. In the context of disease, LL-37 is studied for its involvement in conditions like periodontitis, where its expression is altered. LL-37 can also influence the pathogenesis of viral infections, including HIV and SARS-CoV-2. Therefore, the answer to what does ll 37 do is that it is a master regulator of the innate immune response with diverse and potent biological activities.
LL 37 Dose Protocol
Developing an ll 37 dose protocol for research requires careful consideration of the model and application. While there is no universally standardized ll 37 dose protocol, studies provide valuable references. In a clinical trial examining topical application for venous leg ulcers, ll 37 dose concentrations of 0.5, 1.6, and 3.2 mg/mL were used. The study found that the two lower ll 37 dose groups showed significantly improved healing compared to placebo.
For in vitro studies, typical ll 37 dose ranges from 1 to 50 μg/mL, depending on the cell type and assay. When establishing an ll 37 dose protocol, researchers should always consult primary literature for their specific model and start with the lowest effective concentration. For assistance with an ll 37 dose protocol, contact our research support team.
LL 37 Peptide Sequence
The ll 37 peptide sequence is a key identifier for this compound. The complete ll 37 peptide sequence is LLGDFFRKSKEKIGKEFKRIVQRIKDFLRNLVPRTES. This ll 37 peptide sequence consists of 37 amino acids, starting with two leucine (L) residues, which gives the peptide its name. The amphipathic nature of the ll 37 peptide sequence allows it to form an α-helical structure that is critical for its interaction with microbial membranes. When you source ll 37 peptide for sale from Planex Supplies, the ll 37 peptide sequence is verified to ensure product identity.
LL 37 Antimicrobial Peptide Chart
An ll 37 antimicrobial peptide chart would list the spectrum of organisms inhibited by LL-37. Research has demonstrated that LL-37 is effective against a broad range of pathogens. An ll 37 antimicrobial peptide chart would include Gram-positive bacteria such as Staphylococcus aureus, Gram-negative bacteria like Escherichia coli and Pseudomonas aeruginosa, as well as various fungi and enveloped viruses. This broad-spectrum activity, which can be visualized in an ll 37 antimicrobial peptide chart, highlights its potential as a research tool for studying innate immunity and developing new antimicrobial strategies.
LL-37 Peptide Dosage
Understanding LL-37 peptide dosage is crucial for designing reproducible experiments. The appropriate LL-37 peptide dosage varies based on the research model and route of administration. For topical applications in wound healing studies, LL-37 peptide dosage has been explored at concentrations of 0.5, 1.6, and 3.2 mg/mL. For systemic administration in animal models, LL-37 peptide dosage can range from 0.1 to 10 mg/kg, depending on the species and desired effect. In cell culture, LL-37 peptide dosage is typically reported in micrograms per milliliter, with concentrations ranging from 1 to 50 μg/mL for various assays. When establishing a LL-37 peptide dosage, always consult published literature for your specific application.
