При этом от уровня растворимых и экспрессии мембраносвязанных форм его рецепторов может в значительной степени зависеть эффективность действия иммуномодулирующего цитокина и его роль в развитии патологических состояний организма. По результатам исследования показан ряд достоверных отличий не только в проценте клеток, несущих рецепторы к TNFα, но и в абсолютном количестве экспрессируемых рецепторов на клетках различных субпопуляций иммунокомпетентных клеток в норме и при ревматоидном артрите, установлены корреляционные взаимосвязи этих показателей с сывороточными уровнями самого цитокина и его растворимых рецепторов. Обсуждаются механизмы и роль изменений в экспрессии рецепторов к TNFα на отдельных субпопуляциях лейкоцитов при иммунопатологическом состоянии и в сравнении с условно-здоровыми донорами.</p></abstract><trans-abstract xml:lang="en"><p>TNFα — a multifunctional pleiotropic cytokine, considered to have a special significance in the immunopathogenesis of rheumatoid arthritis. Herewith the effectiveness of immunomodulatory cytokine and its role in the development of pathological states of the organism may depend largely on the content of soluble receptors and expression of membrane-bound receptors. The study shows several significant differences not only in the percentage of cells with. TNFα receptors, but also in the absolute number of receptors expressed on cells from different subsets of immunocompetent cells in health and in rheumatoid arthritis, establishes correlation relationships of these parameters with serum contents of the cytokine and its soluble receptors. The mechanisms and the role of changes in the expression of TNFα receptors in different subsets of leukocytes in immunopathological state and in compare with healthy donors are discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мембранносвязанные рецепторы</kwd><kwd>ревматоидный артрит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>TNFα</kwd><kwd>TNFα</kwd><kwd>membrane-bound receptors</kwd><kwd>rheumatoid arthritis</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">Александрова Ю.Н.
