T-regulatory cells are a specialized subpopulation of T-lymphocytes, which can have an immunosuppressive effect and thus affect the immune response. Goal. The study population of regulatory T-cells in the skin of patients with mycosis fungoides and llaque parapsoriasis. Materials and methods. The content of Foxp3+ and CD3+ cells by immunohistochemical studies of skin biopsy specimens from patients with patch stage mycosis fungoides (10 patients) and plaque parapsoriasis (10 patients). The control group consisted of 16 healthy individuals. Results. Relative expression area Foxp3+ cells in patients with mycosis fungoides patch stage (0.44%) 2.6 times greater than in patients with plaque parapsoriasis (0,14%; p &lt; 0,05). Part the Foxp3+ cells of the total number of T lymphocytes in patients with patch stage mycosis fungoides (5.9%) and plaque parapsoriasis (4.7%) were not significantly different (p &gt; 0,05). Conclusion. In the initial stage of patients with mycosis fungoides determined a statistically significant predominance of the absolute number of T-regulatory cells in the epidermis and in the dermis. Part T-regulatory cells from all of T-lymphocytes in patients with skin patch stage mycosis fungoides and plaque parapsoriasis not statistically significantly different.</p></abstract><trans-abstract xml:lang="ru"><p>Патогенез грибовидного микоза (ГМ) до настоящего времени полностью не изучен. Тем не менее считается, что микроокружение опухолевых клеток может оказывать влияние на развитие малигнизированных лимфоцитов. Т-регуляторные клетки являются специализированной субпопуляцией Т-лимфоцитов, которая способна оказывать иммуносупрессивное воздействие и тем самым влиять на иммунный ответ организма. Цель. Изучение численности популяции Т-регуляторных клеток в коже больных ГМ и бляшечным парапсориазом. Материал и методы. Определяли содержание Foxp3+ и CD3+ клеток методом иммуногистохимического исследования биоптатов кожи у больных пятнистой стадией ГМ (10 пациентов) и бляшечным парапсориазом (10 пациентов). Группу контроля составили 16 здоровых лиц. Результаты. Относительная площадь экспрессии Foxp3+ клеток у больных пятнистой стадией ГМ (0,44%) в 2,6 раза больше, чем у пациентов с бляшечным парапсориазом (0,14%; p &lt; 0,05). Доля Foxp3+ клеток от общего количества Т-лимфоцитов у больных ГМ (5,9%) и пациентов с бляшечным парапсориазом (4,7%) статистически значимо не различается (p &gt; 0,05). Заключение. В начальной стадии у больных ГМ определено статистически значимое преобладание абсолютного количества Т-регуляторных клеток как в эпидермисе, так и в дерме. Доля Т-регуляторных клеток от всех Т-лимфоцитов кожи у больных пятнистой стадией ГМ и бляшечным парапсориазом статистически значимо не различается.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>грибовидный микоз</kwd><kwd>Т-регуляторные клетки</kwd><kwd>бляшечный парапсориаз</kwd><kwd>Т-клеточная лимфома кожи</kwd><kwd>Mycosis fungoides</kwd><kwd>regulatory T-cells</kwd><kwd>plaque parapsoriasis</kwd><kwd>cutaneous T-cell lymphoma</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ackerman A.B.
