From clearing infection to rebuilding skin

At a wound, LL-37 does double duty. It clears invading microbes and, at the same time, pushes the repair program forward: it promotes re-epithelialization as skin cells crawl to close the gap and drives angiogenesis, the growth of new blood vessels that feed healing tissue.

This unit follows LL-37 through the phases of healing, splits its re-epithelialization and vessel-growth roles, maps where it acts in wounded skin, and weighs the clinical evidence, including three randomized topical ulcer trials whose results do not agree. It is the peptide most hopeful application, and also a good test of honest reading.
