The authors disclosed the participation of apoptosis proteins in the development of acantholysis in patients with pemphigus. In this connection, studies of the PERP protein passing apoptosis signals and regulating desmosomal functions in keratinocytes are of interest. There is no information about any studies aimed at the PERP protein expression in patients with pemphigus in available literature. Goal. To assess the PERP protein expression in the skin of patients with pemphigus. Materials and methods. There was a study of 22 patients with pemphigus, a patient with bullous pemphigoid and ten healthy people. The PERP protein expression was studied in the biopsy materials obtained from lesion foci and apparently healthy skin of the patients as well as healthy people using the indirect immunofluorescence method. Results. The PERP protein expression was revealed in patients with pemphigus on areas of apparently intact skin, in lesion foci in the patient with bullous pemphigoid and skin of healthy volunteers in the membrane of keratinocytes from all epidermal layers.The PERP protein expression in the blister operculum in lesion foci in patients with pemphigus was absent. Conclusion. Substantial differences in the PERP protein expression in the blister operculum and apparently intact skin of patients with pemphigus were revealed.
