| Research Abstract |
Recently, it has revealed that Cathepsin activities can invole with the onset of gingival hyperplasia. And some gingival hyperplasia patients are reported to have severe hypertrichosis. Therefore, the purpose of this study is to evaluate cathepsin activities of fibroblasts from patients with gingival hyperplasia and hypertrichosis and healthy person.
The patients' cells showed decrease in Cathepsin-L activities, and increase in Cathepsin-B activities. Furthermore, Cathepsin-L knockout mice have abnormal turn over of hair follicle.
From these results, it is suggested that decreased activity of Cathepsin may play a role to onset of hypertrichosis.
