ABSTRACT

Objective:

To evaluate a potential role of HSP70 in the pathogenesis of oral lichen planus (OLP). Materials and

methods:

The study sample comprised of 30 samples of histopathologically confirmed cases of OLP, which were grouped on the basis of the thickness of the epithelial layer into atrophic, normal (classical) and acanthotic. An immunohistochemical analysis of the expression of HSP-70 protein was done, followed by a quantitative and qualitative analysis of the stained layers. The results were statistically analyzed.

Results:

An increased expression of HSP70 was noted in the basal and suprabasal cells of the epithelium of OLP. A higher count and intensity of HSP70 expression was seen in the basal layer of the epithelium. Greater expression was noted in the epithelium of the atrophic group.

Conclusion:

The expression pattern of HSP70 positively implicates it in the pathogenesis of OLP. A potential role of HSP 70 usage as therapeutic modality is suggested.
RESUMO

Objetivo:

Avaliar o potencial papel do HSP70 na patogênese do líquen plano bucal (LPB).

Materiais e métodos:

A amostra foi composta de casos histologicamente confirmados de LPB, os quais foram agrupados em função da espessura da camada epitelial em atrófica, normal (clássica) e acantose. Uma análise imuno-histoquímicada expressão da proteína HSP70 foi feita, seguida por uma análise quantitativa e qualitativa dascamadas coradas. Os resultados foram analisados estatisticamente.

Resultados:

Um aumento da expressãode HSP70 foi observado nas células basais e suprabasais do epitélio de LPB. A maior contagem e intensidadede expressão HSP70 foi vista na camada basal do epitélio. Maior expressão foi observada no epitélio do grupoatrófica.

Conclusão:

O padrão de expressão de HSP70 demonstrou uma ação positiva do mesmo na patogêneseda LPB. O uso do HSP70 como modalidade terapêutica do LPB é sugerido.
