However, the results ofstudies performed by some foreign and domestic authors, testify to a violation of the functional activity of DCs in patients with chronic hepatitis C (CHC). In order to study the nature of the clinical course of various forms of CHC and for the assessment of the capability of DC to antigen presentation in the 2014-2015 in «Research Institute of Influenza» there was performed a simple comparative clinical study. DC obtained from patients with CHC were found to have high antigen-presenting activity due to the presence on their surface a high level of the expression of MHC class I and II. The maturation of DC is accompanied by a significant increase in the levels of expression of HLA-A, B, C and HLA-DR, irrespective of the degree of liver fibrosis, biochemical activity of alanine aminotransferase or level of viral load.</p></abstract><trans-abstract xml:lang="ru"><p>Дендритные клетки (ДК) являются наиболее профессиональными антигенпрезентирующими клетками, которые одними из первых распознают «сигналы опасности» и запускают высокоспецифические иммунные реакции. Результаты исследований, проведенных некоторыми зарубежными и отечественными авторами, свидетельствуют о нарушении функциональной активности ДК у больных хроническим гепатитом С (ХГС). С целью изучения характера клинического течения различных форм ХГС и оценки способности ДК к презентации антигенов в 2014-2015 гг. в ФГБУ "НИИ гриппа” Минздрава России проведено простое сравнительное клиническое исследование. Установлено, что ДК, полученные от больных ХГС, характеризуются высокой антигенпрезентирующей активностью, что обусловлено высоким уровнем экспрессии на их поверхности MHC 1-го и 2-го классов. Созревание ДК сопровождается существенным повышением уровней экспрессии HLA-A,B,C и HLA-DR вне зависимости от степени фиброза печени, биохимической активности аланинаминотрансферазы или уровня вирусной нагрузки.</p></trans-abstract><kwd-group xml:lang="en"><kwd>HLA-A,B,C</kwd><kwd>HLA-DR</kwd><kwd>dendritic cell</kwd><kwd>chronic hepatitis C</kwd><kwd>antigen presentation</kwd><kwd>Major Histocompatibility Complex</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дендритная клетка</kwd><kwd>хронический гепатит C</kwd><kwd>презентация антигена</kwd><kwd>главный комплекс гистосовместимости тканей</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Medzhitov R., Janeway C.A.
