Description

Product description

LL-37 raw powder CAS 597562-32-8 is the only human cathelicidin antimicrobial peptide (AMP) encoded by the CAMP gene, serving as a critical component of the innate immune system. This 37-amino acid cationic peptide exhibits broad-spectrum antimicrobial activity alongside remarkable immunomodulatory, wound-healing, and anticancer properties, making it a subject of intense research for developing novel therapeutics against infectious diseases, inflammation, and cancer.

LL-37's amphipathic nature enables it to interact with microbial membranes while maintaining solubility in aqueous environments . The GF-17 region (residues 17-32) constitutes the core antimicrobial domain, responsible for most bactericidal activity.

LL-37 also plays an immunomodulatory role by chemotaxis of immune cells, regulating the secretion of inflammatory pro- and anti-inflammatory factors, and coordinating innate and adaptive immunity. LL-37 can also act on vascular endothelial cells and epithelial cells, stimulating angiogenesis and promoting damage repair. Furthermore, dysregulation of LL-37 expression can lead to various diseases. For example, in psoriasis, elevated LL-37 expression may promote autoimmune responses.

LL-37 is produced by two primary cell types:
Neutrophils: Stored in secondary granules as inactive hCAP-18; released upon activation and cleaved to active LL-37.
Epithelial cells: Expressed constitutively or induced in skin, respiratory tract, gastrointestinal tract, oral mucosa, urogenital tract, and ocular surface.

Therapeutic Potential and Limitations of LL-37 raw powder CAS 597562-32-8

Its clinical application is currently limited by several challenges, including:
High Cost: Production of the full-length peptide can be expensive.
Proteolytic Degradation: LL-37 is susceptible to breakdown by proteases present in the body, which limits its stability and half-life.
Cytotoxicity: At high concentrations, LL-37 can be toxic to human host cells.
Researchers are developing modified versions and advanced delivery systems, such as nanoparticles, to overcome these limitations and enhance LL-37's therapeutic potential.

FAQ

01. What is LL-37 raw powder CAS 597562-32-8?

LL-37 is a mature peptide composed of 37 amino acids, produced by cleavage of the human cAMP gene precursor protein hCAP-18 by a protease (such as protease-3). It is a positively charged, amphiphilic α-helix peptide widely found in neutrophils, macrophages, epithelial cells, and various tissues and body fluids such as sweat and saliva.

02. What are the main functions of LL-37 raw powder CAS 597562-32-8?

LL-37 possesses multiple biological activities:

Broad-spectrum antibacterial activity: It inhibits and kills Gram-positive bacteria, Gram-negative bacteria, fungi, and viruses.

Immunomotor activity: It can regulate inflammatory responses, attracting immune cells (such as neutrophils and monocytes) to the site of infection and neutralizing bacterial endotoxins (LPS), preventing excessive inflammation.

Promoting wound healing: It accelerates tissue repair and angiogenesis by promoting the proliferation and migration of cells such as keratinocytes.

Anti-biofilm activity: It inhibits bacterial biofilm formation, which is crucial for treating chronic infections.

03. How does LL-37 raw powder CAS 597562-32-8 kill bacteria?

LL-37 raw powder CAS 597562-32-8 utilizes its cationic properties to preferentially bind to the negatively charged bacterial cell membrane surface. It then inserts into the lipid bilayer, forming transmembrane pores (such as annular pores) or acting as a detergent to disrupt the membrane structure, leading to leakage of bacterial contents and ultimately cell lysis and death.
