Buy LL-37 10mg

LL-37 is the only cathelicidin produced by humans — an endogenous host defense peptide that disrupts bacterial membranes, modulates innate immune responses, promotes wound healing by stimulating epithelial cell migration and angiogenesis, and has anticancer activity against several tumor types. It is upregulated at sites of infection and injury, acting as a first responder in host defense. Topical or injectable LL-37 research focuses on chronic wound healing, antibiotic-resistant infection, and skin conditions where the peptide's multifaceted host defense activity applies.
