January 29, 2018: Cathelicidins are a family polypeptides, known for their antimicrobial properties, that are found in immune and skin cells. About 30 cationic peptides have been isolated in various vertebrates. However, despite amphibians being known for their complex skin polypeptide secretions, only seven cathelicidins have been identified from five amphibian species. Cao et al. (2017) recently isolated a new cationic peptide, Cathelicidin-OA1, from Odorrana andersonii that possess antioxidant properties but no antimicrobial properties. Furthermore, experiments with Cathelicidin-OA1 on mouse models revealed full-thickness skin wound healing properties, which is a first for amphibian cathelicidins. Cathelicidin-OA1 promoted wound-healing by increasing macrophage recruitment to wound sites, resulting in faster skin cell production and tissue formation. These findings help us better understand this family of polypeptides and promise the development of better wound-healing agents. (Written by Ann Chang)
