ABSTRACT
Objective To investigate the expression and distribution of cellular FLICE( Fas-assoelated death domain-like interleukin-I β-converting enzyme-like)-inhibitory protein (c-FLIP) in peripheral blood and lesions of lichen planus patients. Methods Peripheral blood and skin samples were obtained from 30 patients with lichen planns and 20 normal controls. Flow cytometry was used to detect intracellular c-Fl,lP in peripheral T and B lymphocytes, and immunohistochemistry was used to examine the expression of c-FLIP in lesionai tissue. Results Based on the pesitivity rate of c-FLIP, there was a significant increase in T iymphocytes in lichen planus compared with normal controls(6.32%±1. 17% vs 2.28%±0.54%, P < 0.05 ), while no significant difference was found in B lymphocytes between two groups (0.78% ±0. 16% vs 0.69% ± 0. 18%, P >0. 05 ). The expression intensity of c-FLIP in keratinocytes was also higher in lichen planusthanthatinnormalcontrols ( 89.73%± 5.24% vs 121.58% ±7.93% ,P < 0. 01 ). Conclusion c-FLIP is highly expressed in lesions and peripheral T lymphocytes of patients with lichen planus, which suggests the possible involvement of c-FLIP in the proliferation of T lymphocytes in lichen planns.
