Sažetak
A characteristic histological feature of lichen planus is the formation of colloid bodies that represent apoptotic keratinocytes (Sugerman PB, Crit Rev oral biol Med 2002 ; 13:350-365). The apoptotic process mediated by CD8+ cytotoxic T lymphocytes and NK cells mainly involves two distinct pathways, perforin/granzyme and Fas/FasL pathway (Podack ER, J Leukoc Biol 1995 ; 57:548-552). In the present study we have investigated the FasL expression and distribution in the epidermis and dermis of lesional and non-lesional lichen planus skin. Skin biopsy specimens from lesional and non-lesional skin of 10 patients with lichen planus and 8 healthy persons were analysed by immunohistochemistry using biotin-streptavidin-peroxidase method. Statistics were performed using Kolmogorov-Smirnov test to verify the normal distribution of variables and subsequently by Student's t-test. The significant differences in the expression of some lymphocyte subsets, particularly of CD4+ and CD8+ phenotype, were found between lichen planus lesions, non-lesional and healthy skin. The expression of FasL was significantly higher in the lesional compared with non-lesional skin. In conclusion, the accumulation of FasL-positive cells in the lichen planus lesions suggest an active role of Fas/FasL apoptotic pathway in the development of lichen planus.
