Обследовали 6 практически здоровых лиц и 9 больных аллергической бронхиальной астмой (АБА) и 24 – неаллергической БА (НАБА). Экспрессию мРНК Id2 оценивали путем проведения RT-PCR.</p><p>Значимой разницы в экспрессии мРНК Id2 в лимфоцитах при БА и у здоровых лиц не зарегистрировано. Корреляционный анализ выявил значимую прямую связь уровня экспрессии мРНК Id2 с уровнем экспрессии мРНК фермента AID и количеством эозинофилов периферической крови при АБА. У здоровых лиц наблюдается сильная прямая связь экспрессии мРНК Id2 как с содержанием IgE в сыворотке, так и с уровнем экспрессии мРНК его тяжелых цепей (ε-цепей).</p><p>У больных БА, вероятно, имеется дефект реализации функций репрессионного кофактора транскрипции ID2, что в итоге ведет к нарушению негативного контроля за экспрессией фермента AID, участвующего в переключении В-лимфоцитов на синтез IgE.</p></abstract><trans-abstract xml:lang="en"><p>The aim of present study was to evaluate a possible role of Id2 (inhibitor of DNA-binding 2) in pathogenesis of bronchial asthma (BA). We have examined six healthy control persons, nine patients with allergic bronchial asthma (ABA) and twenty-four patients with non-allergic bronchial asthma (NABA). The Id2 mRNA expression was evaluated by means of real-time PCR.</p><p>No significant differences in Id2 mRNA expression levels were revealed between the control and asthma groups. Correlation analysis of Id2 mRNA expression has revealed significant positive correlation with AID (activation-induced cytidine deaminase) mRNA levels and peripheric blood eosinophil contents in ABA. Healthy persons demonstrate strong positive correlation between Id2 mRNA expression and serum IgE levels, like as with ε-chain mRNA contents.</p><p>It was suggested that the Id2 dysfunction may take place in the BA patients. These changes affect negative control over the AID expression, which is important for switching B-cells to IgE production.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бронхиальная астма</kwd><kwd>Id2</kwd><kwd>транскрипция</kwd><kwd>иммуноглобулин E</kwd><kwd>лимфоциты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bronchial asthma</kwd><kwd>Id2</kwd><kwd>transcription</kwd><kwd>immunoglobulin Е</kwd><kwd>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">Минеев В.Н., Нёма М.А., Сорокина Л.Н.
