Поэтому среди разнообразных подходов к патогенетической терапии РА особое место занимает разработка препарата абатацепт (АБЦ), избирательно блокирующего костимуляцию Т-клеток. В обзоре представлены новые данные, касающиеся эффективности и безопасности подкожной лекарственной формы, обсуждены механизмы его действия в отношении подавления синтеза аутоантител, восстановления нормальной функции Т-регуляторных клеток и т. д. Специально рассмотрены механизмы, обеспечивающие синергическое действие АБЦ и метотрексата при РА, перспективы персонифицированной медицины в ревматологии на примере АБЦ.</p></abstract><trans-abstract xml:lang="en"><p>Rheumatoid arthritis (RA) is a systemic autoimmune rheumatic disease characterized by chronic inflammation of the synovial membrane of joints and by a wide spectrum of extra-articular (systemic) manifestations, with the pathological T cell activation that plays a key role in the pathogenesis of this disease. Therefore, the design of abatacept (ABC) that selectively inhibits T cell costimulation occupies a special place among various approaches to the pathogenetic therapy of RA. The review gives novel evidence for the efficacy and safety of its subcutaneous formulation and discusses its mechanism of action in suppressing the synthesis of autoantibodies and in restoring normal regulatory T cell function,etc. Mechanisms for the synergic action of ABC and methotrexate for RA and prospects for personified medicine in rheumatology are specially considered using the drug as an example.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>костимуляция Т-клеток</kwd><kwd>CTLA4</kwd><kwd>абатацепт</kwd><kwd>метотрексат</kwd><kwd>Т-регуляторные клетки</kwd><kwd>аутоантитела к цитруллинированным белкам</kwd></kwd-group><kwd-group xml:lang="en"><kwd>T cell costimulation</kwd><kwd>CTLA-4</kwd><kwd>abatacept</kwd><kwd>methotrexate</kwd><kwd>regulatory T cells</kwd><kwd>anti-citrullinated protein autoantibodies</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">Насонов ЕЛ, Каратеев ДЕ, Балабанова РМ.
