The Expression of TNF-α and ICAM-1 in Lesions of Lichen Planus and Its Implication / 华中科技大学学报（医学）（英德文版）

ABSTRACT

In order to investigate the role of TNF-α and ICAM-1 in the pathogenesis of lichen planus, immunohistechemistty was used to detect the expression of TNF-α and ICAM-1 in skin le- sions of the patients with lichen planus and skin tissues of normal subjects. The results showed that positive rates of TNF-α and ICAM-1 expressions in lichen planus were significantly higher than those in normal skins (both P<0.05). Meanwhile, there was a obvious correlation between the in- crease of TNF-α and that of ICAM-1 in lichen planus. The expression of TNF-α and ICAM-1 might play an important role in the development of lichen planus.
