В качестве антигена использовали альфа (1→3) декстран. Мышей иммунизировали декстраном и на 0, 4, 14, 28 и 56 дни в костном мозге и селезенке определяли количество IgM+ антитело-продуцентов. Фенотип клеток определяли цитометрически. В лимфоцитарной зоне нормального костного мозга было выявлено 4% Ти 80-85% В-лимфоцитов. Наряду с этим было обнаружено ~35% клеток, несущих маркер плазматических клеток – CD138; ~ 3% составляли CD138+IgM+ и ~ 6% – CD138+IgA+ B-лимфоциты. В селезенке на долю Т-клеток приходилось ~50%; В клетки составляли 47%; ~1,5% было представлено CD138+ и ~0,5% CD138+IgM+ лимфоцитами. </p><p>Динамика образования антитело-продуцентов в селезенке и костном мозге мышей при иммунизации декстраном отличалась. В селезенке максимум клеток, секретирующих антитела, выявлялся на 4-й день, к 28-му дню процесс затихал. В костном мозге напротив, на 4-е сутки увеличение числа антитело-продуцентов только начиналось; оно достигало максимума на 14-й день и выходило на стационарный уровень к 28-му. </p><p>В опытах in vitro было установлено, что внесение Т-независимого антигена в культуру клеток костного мозга, выделенных на 28-й день после иммунизации, на их активность не влияет. Ранее это было показано только для Т-зависимых антигенов. </p><p>Специфический маркер долгоживущих плазматических клеток неизвестен. Но для них характерен маркер всех плазматических клеток – CD138. Был отработан метод выделения СD138+ клеток, из костного мозга, позволяющий получить клетки 87-97%-й чистоты. Антитела, продуцируемые CD138+ клетками костного мозга, обогащенными долгоживущими клетками, моноспецифичны.</p></abstract><trans-abstract xml:lang="en"><p>Production kinetics and some functional properties of long-lived marrow plasma cells were studied in mice immunized with T-independent type 2 antigens. Alpha (1→3) dextran was used as an antigen for immunization. The mice were immunized by dextran, and the numbers of IgM antibody producing cells were determined by ELISPOT method. The cell phenotype was determined by cytofluorimetric technique. In the area of normal bone marrow lymphocytes ~4% of T and ~85% of B cells were detected. About 35% of the cells expressed a plasmocyte marker (CD138); 3% were CD138+IgM+, and about 6% of the lymphocytes were double-positive for CD138+IgA+. Among spleen lymphocytes, 50% of T and 47% of B cells were detected. About 1.5% lymphocytes were CD138+, and 0.5% were positive for CD138 and IgM. </p><p>Time kinetics of antibody-producing cells in bone marrow and spleen was different. In spleen populations, the peak amounts of antibody-secreting cells have been shown on the day 4; the process abated by the day 28. Vice versa, the numbers of the antibody-producing cells in bone marrow started to increase on the day 4. The process reached its maximum on day 14, and after 28th day became stationary. The in vitro experiments have shown that supplementation of bone marrow cells from immune mice with dextran did not influence their functional activity. It was previously shown for cells responding to T-dependent antigens only. </p><p>A specific marker for the long-lived plasma cells is still unknown. However, these cells possess a common CD138 marker specific for all plasma cells. A method for isolation of bone marrow CD138+ cells was developed. The CD138+ cells were of 87-97% purity, being enriched in long-lived bone marrow cells, and produced monospecific antibodies. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Т-независимые антигены 2-го типа</kwd><kwd>альфа (1→3) декстран</kwd><kwd>костный мозг</kwd><kwd>CD138+ плазматические клетки</kwd><kwd>долгоживущие плазматические клетки</kwd><kwd>антитело-продуценты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>T-independent type 2 antigens</kwd><kwd>alpha (1→3) dextran</kwd><kwd>bone marrow</kwd><kwd>CD138+ plasma cells</kwd><kwd>long-lived plasmocytes</kwd><kwd>antibody-producing cells</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">Сидорова Е.В.
