LL-37 Complex

What is LL-37 Complex?

LL-37 is a member of the cathelicidin family, recognized as the only known human cathelicidin. This diverse protein family is renowned for its antimicrobial properties. Primarily located in macrophages and polymorphonuclear leukocytes—crucial types of white blood cells—LL-37 exhibits various functions, including antimicrobial, antibacterial, antiviral, and antifungal activities.

In addition to its role in fighting infections, LL-37 is noted for its anti-inflammatory properties, which contribute to immune response regulation. Recent research has further expanded the understanding of LL-37’s impact, revealing potential anticancer effects and indicating its involvement in promoting blood vessel growth, crucial for tissue repair and regeneration. This broad spectrum of functions highlights LL-37’s significance in the immune system’s defense against pathogens and its influence on diverse physiological processes, including autoimmune diseases and wound healing.
