Установлено, что рецидив высыпаний при данном заболевании происходит за счет резидентных клеток памяти кожи. При этом количество СD4+CCR3+ эффекторных клеток памяти периферической крови коррелирует с тяжестью заболевания. Поэтому целью нашей работы является изучение фенотипа клеток памяти периферической крови пациентов с псориазом.</p><p>В исследование включили 6 здоровых доноров: средний возраст – 45,4 (min – 29, max – 55), женщины – 3, мужчины – 3; 10 пациентов с псориазом: женщины – 4 , мужчины – 6, средний возраст – 37,3 (min – 23, max – 57), из них 5 пациентов с PASI более 10 и 5 пациентов с PASI менее 10. Критериями исключения были наличие аутоиммунных, онкологических и гематологических заболеваний, системная терапия иммуносупрессивными препаратами в течение 1 месяца. Пациенты подписали добровольное информированное согласие на участие в исследовании. Выделение мононуклеарных клеток периферической крови проводили в градиенте плотности фиколл-урографина (p = 1,082 г/л) (BioClot GmbH, Германия). Полученные клетки окашивали конъюгированными с флуорохромами моноклональными антителами к поверхностным маркерам CD4+ центральных (Tcm) и эффекторных (Tem) клеток памяти (CD4, CD45RO, CD197), α-цепи рецептора IL-7 (CD127) и γ-цепи рецептора IL-7 (CD132). Фенотипирование клеточных популяций проводили на клеточном анализаторе FACS CantoII. Статистический анализ полученных данных проводили с использованием пакета прикладных программ Statistica 6.0 (Statsoft, США).</p><p>Доля Tcm в периферической крови доноров составляла 33,4% (min – 18,2; max – 43,7), Tem – 28,7% (min – 13.6, max – 38,9), у пациентов с псориазом: Tcm – 28,65% (min – 13,3; max – 59,6), Tem – 21,5% (min – 9.3, max – 38.6). Среди центральных CD4+-клеток памяти доля CD127+CD132- -клеток составляет 26,00%, CD127+CD132+ – 1,69%, CD127+CD132- – 69,00%, CD127- CD132+ – 1,94%. Среди эффекторных CD4+-клеток памяти доля CD127+CD132- -клеток составляет 23,58%, CD127+CD132+ – 1,18%, CD127+CD132- – 69,84%, CD127- CD132+ – 0,70%. Обнаружена прямая корреляционная связь между количеством CD127- CD132+ центральных клеток памяти и значением PASI (r = 0,639, p &lt; 0,05).</p><p>У пациентов с псориазом доля центральных клеток памяти выше, чем у здоровых доноров, при этом количество эффекторных клеток памяти – ниже. Обнаружена прямая корреляционная связь между количеством центральных клеток памяти, экспрессирующих γ-цепь рецептора IL-7, и степенью тяжести заболевания. Высокой экспрессией CD132 характеризуются активированные клетки памяти. Можно предположить, что данная популяция клеток памяти играет роль в поддержании аутоиммунного воспаления у пациентов с данным заболеванием, а также участвует в репопуляции резидентных клеток памяти кожи. </p></abstract><trans-abstract xml:lang="en"><p>Psoriasis is a chronic autoimmune disease in which the skin and joints are involved in the pathological process. It was found that the recurrence of rashes in this disease occurs due to the resident memory cells of the skin. The number of CD4+CCR3+ effector memory cells in peripheral blood correlates with the severity of the disease. Therefore, the aim of our work is to study the phenotype of peripheral blood memory cells in patients with psoriasis.</p><p>The study included 6 healthy donors: average age – 45.4 (min – 29, max – 55), women – 3, men – 3; 10 patients with psoriasis: women – 4, men – 6, average age – 37.3 (min – 23, max – 57), of which 5 patients with PASI &gt; 10 and 5 patients with PASI &lt; 10. The exclusion criteria for the study were the presence of autoimmune, oncological and hematological diseases, systemic therapy with immunosuppressive drugs for 1 month. Patients signed informed consent to participate in the study. Isolation of peripheral blood mononuclear cells was performed in a density gradient of ficoll-urographin (p = 1.082 g/L). Then cells were stained with fluorochrome-conjugated monoclonal antibodies to surface markers of central (Tcm) and effector (Tem) CD4+ memory cells (CD4, CD45RO, CD197), the α-chain of the IL-7 receptor (CD127), and the γ-chain of the IL-7 receptor (CD132). Statistical analysis of the data obtained was performed using the Statistica 6.0 software package.</p><p>The percent of Tcm in the peripheral blood of donors was 33.4% (in – 18.2, max – 43.7), Tem – 28.7% (min – 13.6, max – 38.9), in patients with psoriasis: Tcm – 28.65% (min – 13.3, max – 59.6), Tem – 21.5% (min – 9.3, max – 38.6). In the peripheral blood of patients with psoriasis, among the central CD4+ memory cells, the proportion of CD127+CD132- -cells is 26.00%, CD127+CD132+ – 1.69%, CD127+CD132- – 69.00%, CD127- CD132+ – 1.94%. Among effector CD4+ memory cells, the proportion of CD127+CD132- -cells is 23.58%, CD127+CD132+ – 1.18%, CD127+CD132- – 69.84%, CD127- CD132+ – 0.70%. A direct correlation was found between the number of CD127- CD132+ central memory cells and the PASI value (r = 0.639, p &lt; 0.05).</p><p>In patients with psoriasis, the proportion of central memory cells is higher than in healthy donors, while the number of effector memory cells is lower. A direct correlation was found between the number of central cells expressing the γ-chain of the IL-7 receptor and the severity of the disease. Activated memory cells are characterized by high expression of CD132. It can be assumed that this population of memory cells plays a role in maintaining autoimmune inflammation in patients with this disease, and also participates in the repopulation of skin resident memory cells. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>СD4+-клетки памяти</kwd><kwd>псориаз</kwd><kwd>аутоиммунные заболевания кожи</kwd><kwd>дерматология</kwd><kwd>резидентные клетки памяти</kwd><kwd>индекс PAS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CD4+ memory cells</kwd><kwd>psoriasis</kwd><kwd>autoimmune skin diseases</kwd><kwd>dermatology</kwd><kwd>resident memory cells</kwd><kwd>PASI index</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Boyman O., Hefti H.P., Conrad C., Nickolof B.J., Suter M., Nestle F.O.
