Антиэрготипический ответ является одним из механизмов регуляции Т‑клеточного иммунного ответа. К эрготоп-ассоциированным антигенам относят молекулы, экспрессия которых увеличивается в процессе Т-клеточной активации (например, молекулы CD25 и hsp60). Антиэрготипические клетки распознают иммуногенные эпитопы эрготопа, представленные на поверхности активированной Т-клетки в комплексе с молекулами MHC I и/или II класса. В данной работе была исследована динамика экспрессии HLA-Dr, СD25, hsp60 и мРНК hTERT Т‑лимфоцитами периферической крови здоровых доноров в культуре в ответ на стимуляцию анти-CD3-антителами и IL-2 с реактивацией на 7 сутки. Процент Т‑клеток, экспрессирующих CD25, резко увеличивался (до 90% и более) уже на 3 сутки активации и далее практически не изменялся либо уменьшался незначительно. Содержание hsp60 сначала также возрастало, пик наблюдался на 3 сутки, затем количество белка постепенно снижалось. Экспрессия HLA-Dr увеличивалась по мере активации, с пиком на 8 или 10 сутки. Количество мРНК hTERT также повышалось по сравнению с исходным, с двумя пиками активации: на 3 и на 8 сутки. Антиэрготипический ответ может контролировать аутоиммунитет в отношении активированных Т-клеток, независимо от их антигенной специфичности, поэтому иммунотерапия различных аутоиммунных заболеваний, нацеленная на активацию антиэрготипического ответа, может представлять клинический интерес.</p></abstract><trans-abstract xml:lang="en"><p>Abstract. Anti-ergotypic response is considered to contribute significantly to the regulation of immune response. Ergotope-associated antigenic determinants include molecules upregulated on the surface of activated T cells (CD25, hsp60 and others). Anti-ergotypic cells are directed against these surface determinants usually complexed to MHC-I and/or MHC-II. Here we demonstrate regulated expression of HLA-Dr, СD25, hsp60 and hTERT mRNA during in vitro activation of peripheral T-lymphocytes with anti-CD3 antibodies and IL - 2, with reactivation on day 7. The percentage of CD25-expressing T cells showed sharp increase as early, as by the day 3 of activation, and it varied only slightly at later terms. The hsp60 levels rose as well, reached a peak at day 3, and gradually decreased thereafter. HLA-Dr expression was induced upon the activation, with a peak at the days 8 or 10. hTERT mRNA amounts also increased, as compared with baseline values, showing two peaks at the days 3 and 8. Anti-ergotopic response may control autoimmunity by targeting the activated T cells, regardless of their specificity. Therefore, immunotherapy of different autoimmune disorders aiming to activate anti-ergotopic responses, may be of a sufficient clinical interest.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эрготоп</kwd><kwd>антиэрготипическая регуляция</kwd><kwd>Т-лимфоциты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ergotope</kwd><kwd>anti-ergotypic response</kwd><kwd>Т-lymphocytes</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">Способ лечения атопического дерматита / Кожевников В.С., Баровская Н.А, Королькова О.Ю, Непомнящих В.М., Леонова М.И., Демина Д.В. – № 2007112582/14 (013652), заявка на изобретение, приоритет от 04.04.07, дата положительного решения 05.05.2008.
