Expression of Cathepsin B and Cystatin A in Oral Lichen Planus.

Objective: Cathepsin B (Cat-B), a cysteine protease, and cystatin A (Cys-A), a protease inhibitor, are involved in the immune response. This study determined Cat-B and Cys-A expression in oral lichen planus (OLP) by immunohistochemistry.

Materials And Methods: Thirty specimens each of OLP and healthy gingiva (HG) were included.

Palatal Inflammation and the Presence of in Denture-Wearing Patients.

Aim: Denture stomatitis (DS) is a common inflammatory reaction in denture wearers. The severity of palatal inflammation in DS is believed to be related to colonization. The present study evaluated the presence of at the palatal and the denture surface.

The expression of Cathepsin L in oral lichen planus.

Background: Malignant transformation of oral lichen planus (OLP) was reported particularly in erosive type, however, it remains inconclusive. Cathepsin L was shown to promote tumor growth and invasion in many cancers. Therefore, cathepsin L expression in erosive and non-erosive OLP compared with oral epithelial dysplasia and oral squamous cell carcinoma (OSCC) were investigated.
