Expression of TNF-? and TGF-? in oral lichen planus patients / 中国病理生理杂志

ABSTRACT

AIM: To investigate the expression of TNF-?, TGF-? in patients with oral lichen planus (OLP) and normal oral mucosa (NOM). METHODS: An immunohistochemical technique was performed to detect TNF-?, TGF-?_1 and TGF-?_2 expression in 22 cases with OLP and 10 normal controls. RESULTS: In lamina propria of OLP, the expression of TNF-? and TGF-?_1 were increased, whereas TGF-?_2 did changed significantly compared with control group. TNF-? positive signal were mostly found in macrophages, lymphocytes. TGF-?_1 positive cell was present in macrophages, endothelial cells and fibrocytes. CONCLUSION: TNF-? and TGF-?_1 play an important role in the development and maintenance of OLP local inflammation.
