В частности, показано, что изменения в иммунной системе, приводящие к заболеванию системной красной волчанкой (СКВ), нередко сопровождаются изменениями числа тромбоцитов и их активности в периферической крови больных СКВ, коррелирующими с выраженностью клинических проявлений болезни. В предыдущие годы нами была детально исследована одна из стандартных экспериментальных моделей СКВ, основанная на индукции хронической реакции «трансплантат против хозяина» (хРТПХ) в полуаллогенной системе DBA/2 → (C57Bl/6 x DBA/2)F1. Однако участие тромбоцитов в этом иммунопатологическом процессе исследовано не было, и в литературе нет данных о поведении тромбоцитов при хРТПХ или о связи их с состоянием Th1/Th2-баланса, хотя по аналогии с развитием СКВ у человека можно ожидать, что и в использованной нами экспериментальной модели количество тромбоцитов изменяется в соответствии с развитием хРТПХ. Поэтому целью данной работы было определение числа тромбоцитов в крови у мышей с Th1и Th2-зависимыми вариантами хРТПХ.</p><p>В экспериментах были использованы самки мышей линий DBA/2 и гибридов (C57Bl/6 × DBA/2)F1. Хроническую РТПХ в полуаллогенной системе индуцировали вводя спленоциты мышей DBA/2 мышам-гибридам B6D2F1: по 60-70 × 106 клеток в/в двукратно с интервалом в 6 дней. Исследуемые параметры оценивали через три месяца после начала экспериментa и формирования люпус-подобного гломерулонефрита у животных с Th2-зависимым вариантом хРТПХ.</p><p>Снижение количества эритроцитов и гемоглобина, уменьшение показателей гематокрита и параллельное увеличение количества ретикулоцитов в крови мышей с хРТПХ хорошо согласуется с ранее сделанным нами выводом о наличии у этих животных аутоиммунной гемолитической анемии. Было обнаружено, что в отличие от других форменных элементов крови тромбоциты существенно возрастают при развитии хРТПХ, но о вторичном тромбоцитозе в данной модели СКВ можно говорить только в отношении Th2-зависимого варианта этого процесса, в то время как в группе с Th1-зависимым вариантом хРТПХ среднее количество тромбоцитов в крови не отличается от контрольной группы.</p></abstract><trans-abstract xml:lang="en"><p>As found in clinical and laboratory studies, platelets not only play a key role in the processes of coagulation and thrombosis, but are also able to actively participate in other pathophysiological processes, including the development of immune reactions. It has been shown that changes in the immune system leading to systemic lupus erythematosus (SLE) are often accompanied by changes in the number of platelets and their activity in the peripheral blood of SLE patients, which correlate with the severity of the clinical manifestations of the disease. Earlier we have studied the standard experimental model of SLE in detail, based on the induction of chronic graft-versus-host disease (cGVHD) in the semi-allogeneic system DBA/2 → (C57Bl/6 x DBA/2)F1. However, the participation of platelets in this immunopathological process has not been studied. There are no data in the literature on the behavior of platelets in cGVHD or on their relationship with the state of Th1/Th2 balance. It can been expected that the platelet count changes according to the development of cGVHD in the used experimental model by analogy with the development of SLE in humans.</p><p>In the experiments, we used female mice of the DBA/2 strain and (C57Bl/6 × DBA/2)F1 hybrids. Chronic GVHD in a semi-allogeneic system was induced by injecting DBA/2 mouse splenocytes into B6D2F1 hybrid mice: 60-70 × 106 cells intravenously twice with an interval of 6 days. The studied parameters were evaluated three months after the start of the experiment and the formation of lupus-like glomerulonephritis in animals with Th2-dependent cGVHD variant.</p><p>A decrease in the number of erythrocytes and hemoglobin, a decrease in hematocrit and a parallel increase in the number of reticulocytes in the blood of mice with cGVHD are in good agreement with our earlier conclusion that these animals have autoimmune hemolytic anemia. It was found that, platelets increase significantly with the development of cGVHD unlike other blood cells. Secondary thrombocytosis is observed in the case of the Th2-dependent variant of сGVHD in this model of SLE, while in the group with the Th1-dependent variant of сGVHD, the average number of platelets in the blood does not differ from the control group.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая реакция трансплантат против хозяина</kwd><kwd>cистемная красная волчанка</kwd><kwd>экспериментальная модель</kwd><kwd>тромбоциты</kwd><kwd>Th1/ Th2-баланс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic graft-versus-host disease</kwd><kwd>systemic lupus erythematosus</kwd><kwd>experimental model</kwd><kwd>platelets</kwd><kwd>Th1/Th2 balance</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The investigation was financed from the federal budget to fulfill the state assignment on the research work "The study of the immunopathogenesis of phenotypes of socially significant human diseases, polymorbid diseases, the development of new methods for their personalized diagnosis and treatment" (state registration No. 122012000366-9).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Castellino G., Govoni M., Prandini N., Limpido G., Bernardi S., Campione D., Lanza F., Trotta F.
