Предшествующее деструкции воспаление может быть вызвано механической нагрузкой на суставы, аутоиммунными реакциями. В последнее время IL-7 рассматривают как один из ключевых цитокинов, способствующих продукции матриксных металлопротеиназ, катаболических ферментов, Т-клеточноопосредованной активации моноцитов, созреванию остеокластов. Растворимая форма рецептора к IL-7 может способствовать увеличению продолжительности жизни IL-7 и тем самым обеспечивать биодоступность цитокина и опосредовать эффект IL-7 на клетки. Целью данного исследования стало определение растворимой формы рецептора к IL-7 (sIL-7R) в плазме крови пациентов с ревматоидным артритом (RA), остеоартритом (OA), псориатическим артритом (PsA) и вульгарным псориазом (PS), а также здоровых индивидуумов. Пациенты с RA, вошедшие в исследование, имели умеренную и высокую активность заболевания согласно индексу DAS28. Пациенты с PsA преимущественно имели умеренную и низкую активность заболевания (DAS28) и характеризовались легкой и средней степенью тяжести заболевания (PASI). В соответствии с индексом PASI в исследование были включены пациенты с PS с легким и тяжелым течением заболевания. У всех пациентов с OA был метаболический фенотип, который сопровождается повышенным индексом массы тела.</p><p>sIL-7R определяли в плазме крови методом иммуноферментного анализа. Было обнаружено, что у пациентов с артропатией повышен уровень растворимой формы IL-7 относительно здоровых индивидуумов, исключение составила группа пациентов с PsA. Также высокая концентрация sIL-7R наблюдалась у пациентов с PS. Проведя анализ с учетом клинических характеристик пациентов, мы установили, что уровень sIL-7R повышался у пациентов с RA и PsA с высокой активностью заболевания по DAS28. Кроме того, были выявлены положительные корреляционные связи между концентрацией sIL-7R и DAS28 при RA и PsA. У пациентов с PsA со средне-тяжелой степенью тяжести (PASI) концентрация sIL-7R также была повышена относительно донорских значений. Напротив, у пациентов с PS высокий уровень sIL-7R фиксировался вне зависимости от степени тяжести заболевания. У пациентов с OA не было выявлено взаимосвязей между уровнем sIL-7R и клиническими параметрами.</p><p>Таким образом, повышенный уровень sIL-7R у пациентов с артропатией может говорить о вовлеченности IL-7 и его рецепторной системы в патогенез суставных заболеваний. Рецептор IL-7 может стать перспективной мишенью как в терапии заболеваний суставов, так и других аутоиммунных заболеваний, включая псориаз.</p></abstract><trans-abstract xml:lang="en"><p>Arthropathy is one of the most prevalent diseases, which are based on the destruction and remodeling of cartilage and bone tissue. The inflammation that precedes destruction can be caused by mechanical stress on the joints, or by autoimmune reactions. Recently, IL-7 is considered as one of the key cytokines that promote the production of matrix metalloproteinases, catabolic enzymes, T cell-mediated activation of monocytes, and maturation of osteoclasts. The soluble form of the IL-7 receptor can help prolong the lifespan of IL-7 and thereby it ensures the bioavailability of the cytokine and mediates effect of IL-7 on cells. The aim of this study was to determine the soluble form of the IL-7 receptor (sIL-7R) in the blood plasma of patients with rheumatoid arthritis (RA), osteoarthritis (OA), psoriatic arthritis (PsA) and psoriasis vulgaris (PS), as well as healthy individuals. The RA patients included in the study had moderate to high disease activity according to the DAS28 index. Patients with PsA predominantly had moderate and low disease activity (DAS28) and were characterized by mild to moderate disease severity (PASI). In accordance with the PASI index, patients with PS with mild and severe severity of the disease were included in the study. All patients with OA had a metabolic phenotype that is accompanied by an elevated body mass index.</p><p>sIL-7R was determined in blood plasma by enzyme-linked immunosorbent assay. It was found that in patients with arthropathy, the level of soluble form of IL-7 was increased relative to healthy individuals, with the exception of the group of patients with PsA. Also, a high concentration of sIL-7R was observed in patients with PS. Analyzing the clinical characteristics of the patients, we found that sIL-7R levels were elevated in RA and PsA patients with high disease activity by DAS28. In addition, positive correlations were found between the concentration of sIL-7R and DAS28 in RA and PsA. In patients with PsA with moderate severity of the disease (PASI), the concentration of sIL-7R was also increased relative to donor's values. On the contrary, in patients with PS, a high level of sIL-7R was noted regardless of the severity of the disease. In patients with OA, no relationship was found between sIL-7R levels and clinical parameters.</p><p>Thus, an elevated level of sIL-7R in patients with arthropathy may indicate the involvement of IL-7 and its receptor system in the pathogenesis of joint diseases. The IL-7 receptor may become a promising target both in the treatment of joint diseases and other autoimmune diseases, including psoriasis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>растворимый рецептор IL-7</kwd><kwd>иммуноферментный анализ</kwd><kwd>псориатический артрит</kwd><kwd>псориаз</kwd><kwd>ревматоидный артрит</kwd><kwd>остеоартрит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>soluble IL-7 receptor</kwd><kwd>enzyme-linked immunosorbent assay</kwd><kwd>psoriatic arthritis</kwd><kwd>psoriasis</kwd><kwd>rheumatoid arthritis</kwd><kwd>osteoarthritis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данная работа выполнена при поддержке Российского научного фонда и правительства Новосибрской области (проект РНФ № 22-25-20212).</funding-statement><funding-statement xml:lang="en">This study was supported by the Russian Science Foundation and the government of Novosibirsk region (project RSF No. 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">Al-Mossawi H., Yager N., Taylor C.A., Lau E., Danielli S., de Wit J., Gilchrist J., Nassiri I., Mahe E.A., Lee W., Rizvi L., Makino S., Cheeseman J., Neville M., Knight J.C., Bowness P., Fairfax B.P.
