| Outline of Final Research Achievements |
Leptin, a circulating anti-obesity hormone, exhibits many physiological properties. Recently, leptin was isolated from saliva. In this study, we investigated the physiological role of leptin in the oral cavity by focusing on its effect on wound healing in the oral mucosa. As a result, topical administrarion of leptin significantly promoted wound healing and shortened the duration required for complete healing. Histological analysis of gingival tissue beneath the ulceration showed a denser distribution of blood vessels in the leptin-traeted group. Also, migration of human oral epithelial cells was accelerated in the presence of leptin. From these facts, topically administration leptin was shown to promote wound healing on the oral mucosa by accelerating epithelial cell migration and enhancing angiogenesis around the wounded area. These results strongly suggest that topical administration of leptin may be useful as a treatment to promote wound healing in the oral mucosa.
