Description
LL-37 Peptide – Antimicrobial Defense & Immune Support
LL-37 is a naturally occurring antimicrobial peptide derived from human cathelicidin (hCAP18). It plays a vital role in the innate immune system, acting as a first-line defense against bacterial, viral, and fungal infections. LL-37 is known for its ability to neutralize pathogens, regulate immune responses, and promote wound healing and tissue regeneration.
How LL-37 Works
LL-37 functions by disrupting microbial membranes, making it an effective broad-spectrum antimicrobial agent. Additionally, it exhibits anti-inflammatory and immunomodulatory properties, helping to balance immune responses while preventing excessive inflammation. Research suggests LL-37 may also contribute to tissue repair and wound healing, making it a promising candidate for regenerative medicine applications.
