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 a small human ulcer trial. It is the peptide most hopeful application, and also a good test of honest reading.
