Насущной задачей в оптимизации терапии БА, особенно тяжелой (ТБА), является установление патобиологических механизмов, лежащих в основе формирования фенотипов, или т. н. эндотипов БА. Несмотря на то, что автор настоящей статьи признает, что не-Т2-эндотип БА является не менее серьезной проблемой, настоящая статья посвящена Т2-эндотипу БА (Т2-БА), при этом акцент на изучении Т2-БА обусловлен тем фактом, что существующие на сегодняшний день биологические препараты предназначены именно для популяции пациентов с БА и Т2-опосредованным воспалением. В статье обсуждаются современные характеристики неконтролируемой, трудной для лечения и ТБА, механизмы формирования эозинофильного воспаления при Т2-БА, основные клетки и медиаторы, а также биомаркеры Т2-БА.</p></abstract><trans-abstract xml:lang="en"><p>Bronchial asthma is a heterogeneous disease with variable course. Identification of pathobiological mechanisms of asthma phenotype, also called as asthma endotypes, is an urgent task to optimize treatment of asthma, especially of severe asthma. Although the author recognizes that T2-low asthma is a serious problem, this article is devoted to the T2-high asthma endotype. Currently, biological agents are available for T2-high asthma only, so the focus on T2 high asthma is important. Current characteristics of uncontrolled, difficult-to-treat and severe asthma, mechanisms of eosinophilic inflammation in T2-high asthma, main cells and mediators involved in the disease, and biomarkers of T2-high asthma were discussed in the article.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Т2-бронхиальная астма</kwd><kwd>тяжелая бронхиальная астма</kwd><kwd>фенотип</kwd><kwd>эндотип</kwd><kwd>интерлейкины-4</kwd><kwd>-5</kwd><kwd>-13</kwd><kwd>биомаркеры Т2-воспаления</kwd><kwd>биологическая терапия бронхиальной астмы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>T2-high asthma</kwd><kwd>severe asthma</kwd><kwd>phenotype</kwd><kwd>endotype</kwd><kwd>interleukin 4</kwd><kwd>interleukin 5</kwd><kwd>interleukin 13</kwd><kwd>biomarkers of T2 inflammation</kwd><kwd>biological therapy for asthma</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">Soriano J.B., Abajobir A.A., Abate K.H. et al.
