LL-37, fully named human antimicrobial peptide LL-37, is an innate "intelligent defense master" within our body. It serves not only as a core warrior in the innate immune system but also plays multiple roles as an alarm signal, conductor, and repair engineer. As the only antimicrobial peptide derived from the cathelicidin family in humans, it is rapidly produced by epithelial and immune cells in response to infection or injury. With its unique cationic amphipathic α-helical structure, it acts like a "molecular key" that accurately recognizes and physically disrupts the cell membranes of negatively charged microbes (including bacteria, fungi, and enveloped viruses), leading to rapid pathogen destruction. Since its mechanism relies on physical attack rather than target inhibition, it hardly induces drug resistance. Yet its marvel extends far beyond direct antimicrobial action—it functions as the "strategic hub" of the immune system, recruiting reinforcements like neutrophils through chemotaxis and meticulously regulating the initiation and resolution of inflammation to prevent excessive immune damage to host tissues. Simultaneously, it acts as an "ignition engine" for tissue repair, promoting epithelial cell migration, angiogenesis, and extracellular matrix remodeling to accelerate wound healing. From combating drug-resistant infections and treating chronic refractory wounds to modulating autoimmune inflammation such as in psoriasis, and even serving as a functional skincare ingredient for barrier repair, LL-37 demonstrates tremendous potential spanning basic immunology to clinical translation, standing as a vital molecular bridge connecting the body’s defense, balance, and regenerative wisdom.
