The destruction mechanisms of erythrocytes loaded with autoantibodies are well studied; however, the initial mechanisms that trigger the production of antibodies to own erythrocytes antigens remain unclear. In the pathogenesis of autoimmune hemolytic anemia, an important role is played by impaired immunological tolerance, in which T-lymphocytes play a key role. The study of T-lymphocytes subpopulation in patients with autoimmune hemolytic anemia by flow cytometry can provide valuable information for studying the disease pathogenesis and developing new approaches to its treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Аутоиммунная гемолитическая анемия – редкое заболевание, характеризующееся появлением антиэритроцитарных аутоантител и последующим разрушением эритроцитов клетками иммунной системы. Механизмы разрушения эритроцитов, нагруженных аутоантителами, достаточно хорошо изучены, однако инициальные механизмы, запускающие продукцию антител к антигенам собственных эритроцитов, остаются неясными. В патогенезе аутоиммунной гемолитической анемии важная роль отводится нарушению иммунологической толерантности, в которой ключевую роль играют Т-лимфоциты. Исследование субпопуляционного состава Т-лимфоцитов у больных аутоиммунной гемолитической анемией методом проточной цитометрии может предоставить ценную информацию для изучения патогенеза данного заболевания и разработки новых подходов к его лечению.</p></trans-abstract><kwd-group xml:lang="en"><kwd>autoimmune hemolytic anemia</kwd><kwd>cold agglutinin disease</kwd><kwd>autoantibodies</kwd><kwd>hemolysis</kwd><kwd>T-helpers</kwd><kwd>T-killers</kwd><kwd>regulatory T-cells</kwd><kwd>flow cytometry</kwd><kwd>rituximab</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>аутоиммунная гемолитическая анемия</kwd><kwd>холодовая агглютининовая болезнь</kwd><kwd>аутоантитела</kwd><kwd>гемолиз</kwd><kwd>Т-хелперы</kwd><kwd>Т-киллеры</kwd><kwd>регуляторные Т-клетки</kwd><kwd>проточная цитометрия</kwd><kwd>ритуксимаб</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Freedman J.
