Ремиссия при данном виде заболевания достигается крайне редко и требует постоянного использования фармакотерапии. В связи с этим необходимо подробно изучать патогенез РА для поиска новых мишеней лекарственных препаратов. Известно, что в развитии РА принимают участие T-хелперы (Th)1 и Th17. Однако некоторые исследователи предполагают, что в развитии РА играют роль ILC. ILC являются «врожденными аналогами» Th, ввиду того, что данная субпопуляция синтезирует такие же цитокины. ILC1 является врожденными аналогами Th1, ILC2-Th2, ILC3-Th17. ILC представляют собой резидентные в тканях врожденные лимфоидные клетки, которые имеют функциональное разнообразие и регулируют направленность иммунного ответа с помощью продукции цитокинов.</p><p>В качестве материала мы использовали мононуклерные клетки периферической крови (МНК ПК) от пациентов (n = 19) и условно-здоровых доноров (n = 10). Группа пациентов была разделена в зависимости от терапии: ГИБП и МТХ, а также в зависимости от стадии РА (ранний и очень ранний артрит, развернутый и поздний). МНК ПК были окрашены моноклональными антителами и определялись как Lin-CD127+, в общей популяции оценивали количество CD294+ILC (ILC2), CD117-CD294-ILC были идентифицированы как ILC1, а CD117+СD294-ILC были определены как ILC3.</p><p>Мы получили следующие результаты: количество ILC1 было достоверно снижено у пациентов, получавших МТ по сравнению с пациентами, находящимися на ГИБП и условно здоровыми донорами. Однако пациенты на МТХ с поздней стадией РА имели низкие уровни ILC2 и ILC3 по сравнению с пациентами на ГИБП. Доля ILC2 достоверно возрастала у пациентов на ранних стадиях РА по сравнению с пациентами с поздней стадией РА. Однако ILC1 были значительно снижены у пациентов, получавших МТХ, а ILC3 значительно увеличились у пациентов, получавших МТХ по сравнению с ГИБП.</p><p>Экспрессия PD1 на ILC1 была повышена по сравнению с пациентами, получавшими ГИБП. Однако ILC3 пациентов с поздними стадиями на МТХ имели повышенную экспрессию PD1 по сравнению с пациентами, принимавшими ГИБП. ILC3 доноров был значительно повышен по сравнению с пациентами на ГИБП.</p></abstract><trans-abstract xml:lang="en"><p>Autoimmune diseases currently take a leading place in terms of frequency of occurrence in the population, among which 1 percent is occupied by rheumatoid arthritis (RA). Remission in this type of disease is extremely rare and requires constant use of pharmacotherapy. Studying the pathogenesis of RA is necessary to study to search for new drug targets. It is known that T helpers 1 (Th) and Th17 are involved in the development of RA. However, some researchers suggest that ILCs play a role in the development of RA. ILCs are “innate analogues” of Th, due to the fact that this subpopulation synthesizes the same cytokines. ILC1 is innate analogs of Th1, ILC2-Th2, ILC3-Th17. ILCs are tissue-resident innate lymphoid cells that have functional diversity and regulate the direction of the immune response through the production of cytokines.</p><p>We used peripheral blood mononuclear cells (PBMCs) from patients (n = 19) and conditionally healthy donors (n = 10) as material. The group of patients was divided biologic disease-modifying anti-rheumatic drugs (bDMARDs) and Metotrexate (MTX) and of stage of RA (early and very early arthritis, advanced and late). PBMCs were stained with monoclonal antibodies. ILCs were identified as Lin-CD127+, CD294+ILCs (ILC2) were measured in the general population, CD117-CD294-ILCs were identified as ILC1, and CD117+CD294-ILCs were identified as ILC3.</p><p>We obtained the following results: ILC1 was significantly reduced in patients treated with MTX comparison with patients on bDMARDs and healthy donors. However, patients on MTX with advanced RA had low levels of ILC2 and ILC3 compared to patients on bDMARDs. ILC2 significantly increased in patients with early stages of RA comparison with patients with advanced RA. However, ILC1 was significantly reduced in patients treated with MTX, and ILC3 increased significantly in patients treated with MTX comparison with bDMARDs. Expression of PD1 on ILC1 was increased compared to patients treated with bDMARDs. However, ILC3 patients with advanced stages on MTX had increased expression of PD1 comparison with patients taking bDMARDs. The ILC3 of donors was significantly increased comparison with patients on bDMARDs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>врожденные лимфоидные клетки</kwd><kwd>ревматоидный артрит</kwd><kwd>контрольные точки иммунного ответа</kwd><kwd>проточная цитометрия</kwd><kwd>цитокины</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ILC</kwd><kwd>rheumatoid arthritis</kwd><kwd>immune checkpoint molecules</kwd><kwd>flow cytometry</kwd><kwd>cytokines</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках темы НИР № 122012000366-9 «Изучение иммунопатогенеза фенотипов социально значимых заболеваний человека и полиморбидности как основа для разработки новых методов персонифицированной диагностики и лечения».</funding-statement><funding-statement xml:lang="en">The study was carried out within the framework of research project No. 122012000366-9 “Study of the immunopathogenesis of phenotypes of socially significant human diseases and polymorbidity as a basis for the development of new methods of personalized diagnosis and treatment”.</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">Bal S.M., Golebski K., Spits H.
