Центральное место в патогенезе ПсА занимают взаимодействия между иммунными клетками, главным образом Т-лимфоцитами, и клетками костно-суставной системы. Th1, Th17 цитокины, связанные с развитием ПсА, способствуют повышению уровня продукции цитокинов, хемокинов, матриксных металлопротеиназ, адгезионных молекул иммунными клетками, хондроцитами, фибробластами, индукции остеокластов, что приводит к разрушению хрящевой и костной ткани.</p><p>Среди цитокинов, потенциально вовлеченных в патогенез псориатического артрита, особый интерес вызывает IL-7. IL-7 известен как фактор выживаемости Т-клеток, однако, он может способствовать выработке IFNγ и TNFα Т-лимфоцитами. IL-7 может опосредованно способствовать созреванию остеокластов и деградации хряща. Целью данной работы было исследовать in vitro влияние IL-7 и блокады α-цепи рецептора IL-7 (IL-7R) на продукцию Т-клетками IL-5, IL-13, IL-2, IL-6, IL-9, IL-10, IFNγ, TNFα, IL-17A, IL-17F, IL-4, IL-22 в норме и при псориатическом артрите.</p><p>В исследование было включено 14 пациентов с ПсА в стадии обострения основного заболевания и 8 условно-здоровых доноров. Для определения концентрации цитокинов проводили мультиплексный анализ с помощью проточной цитофлуорометрии.</p><p>Показано, что in vitro IL-7 способствует усилению продукцииTh1, Th2, Th17, Th22, Th9 цитокинов как у пациентов с ПсА, так и у здоровых индивидуумов. Исключение составила продукция IL-2 для обеих групп. При применении блокады α-цепи рецептора IL-7 с помощью моноклональных антител происходит увеличение уровня IL-6 и снижение продукции IFNγ, TNFα, IL-17F, IL-10, IL-5, IL-9 клетками доноров и продукции IFNγ, TNFα, IL-22, IL-2, IL-4, IL-5, IL-13, IL-9 клетками пациентов с ПсА относительно продукции клеток, стимулированных IL-7. У доноров блокада способствовала изменению баланса Th1/Th2 цитокинов: уровень продукции IL-4, IL-13 не изменялся на фоне снижения продукции IFNγ, TNFα. У пациентов с ПсА в условии блокады рецептора IL-7 на повышенном уровне сохранялась продукция IL-10 и происходило уменьшение концентрации IFNγ, TNFα и IL-2, активно задействованных в механизме повреждения тканей. Полученные данные говорят о перспективе применения рецептора IL-7 в качестве таргетной мишени для терапии псориатических заболеваний.</p></abstract><trans-abstract xml:lang="en"><p>Psoriatic arthritis (PsA) is a chronic immune-mediated inflammatory joint disease, often associated with psoriasis. Interactions between immune cells, mainly T lymphocytes, and cells of the osteoarticular system are central in the pathogenesis of PsA. Th1, Th17 cytokines associated with the development of PsA contribute to an increase in the production of cytokines, chemokines, matrix metalloproteinases, adhesion molecules by immune cells, chondrocytes, fibroblasts, and induction of osteoclasts. That leads to the destruction of cartilage and bone tissue. Among the cytokines potentially involved in the pathogenesis of PsA, IL-7 is of particular interest. IL-7 is a T cell survival factor. However, it can promote the production of IFNγ and TNFα by T cells. IL-7 may indirectly promote osteoclast maturation and cartilage degradation. The aim was to investigate the effect of IL-7 and blockade of the α-chain of the IL-7 receptor (IL-7R) in vitro on the production of IL-5, IL-13, IL-2, IL-6, IL-9 IL-10, IFNγ, TNFα, IL-17A, IL-17F, IL-4, and IL-22 by T cells in norm and PsA.</p><p>The study included 14 patients with PsA in the acute stage of the disease and 8 healthy individuals. To determine cytokines concentration, multiplex analysis was performed using flow cytometry.</p><p>It was shown that IL-7 enhances the production of Th1, Th2, Th17, Th22, and Th9 cytokines in both patients with PsA and healthy individuals. The exception was IL-2 for both groups. Under the blockade of IL-7R with monoclonal antibodies, the level of IL-6 increases and production of IFNγ, TNFα, IL-17F, IL-10, IL-5, and IL-9 by donors’ cells and production of IFNγ, TNFα, IL-22, IL-2, IL-4, IL-5, IL-13, and IL-9 by cells from patients with PsA decreases relative to production of cells stimulated with IL-7. In donors, the blockade contributed to a change in the balance of Th1/Th2 cytokines: level of IL-4, IL-13 did not change on the background of a decrease in production of IFNγ, TNFα. In patients with PsA, under blockade of IL-7R the production of IL-10 remained at an increased level and concentration of IFNγ, TNFα and IL-2, which are actively involved in the tissue damage mechanisms, decreased. The obtained data indicate the prospect of using the IL-7R as a target for the treatment of psoriatic diseases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>IL-7</kwd><kwd>блокада альфа цепи рецептора интерлейкина-7</kwd><kwd>Т-хелперы</kwd><kwd>цитокины</kwd><kwd>псориатический артрит</kwd><kwd>мультиплексный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>IL-7</kwd><kwd>T helper cells</kwd><kwd>cytokines</kwd><kwd>blockade of alpha-chain of interleukine-7 receptor</kwd><kwd>psoriatic arthritis</kwd><kwd>multiplex analysis</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Данная работа выполнена при поддержке Российского научного фонда и правительства Новосибирской области (региональный проект РНФ № 22-25-20212).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Блинова Е.А., Ангельская О.А., Козлов В.А.
