Методом проточной цитофлуориметрии определяли уровень поверхностной экспрессии нейтрофилами Fc-gamma рецепторов (CD64, CD32, CD16), фагоцитарную активность и кислородный взрыв гранулоцитов, стимулированных флуоресцентно меченными Escherichia coli.</p></sec><sec><title>Результаты</title><p>Результаты: исследованы образцы крови 10 доношенных, 20 недоношенных с НМТ, 18 недоношенных с ЭНМТ и ОНМТ. Экспрессия CD64 у недоношенных при рождении была выше, чем у доношенных детей, и составила 6,0 (5,3; 9,8), 7,1 (5,1; 11,5) и 4,27 (2,4; 5,8) MFI соответственно (p = 0,013). Экспрессия CD16 у недоношенных, напротив, была ниже: 99,7 (71,3; 126,0) и 80,9 (58,7; 114,8) и 125,3 (95,5; 144,1) MFI соответственно (p = 0,021). К концу 1-го мес жизни у недоношенных новорожденных экспрессия CD16 нейтрофилами периферической крови увеличилась до 126,6 (110,1; 129,0) MFI у детей с ОНТ и до 118,5 (99,5; 132,2) MFI — у детей с ОНМТ/ЭНМТ. Экспрессия CD32 в сравниваемых группах не различалась. Установлена корреляция между интенсивностью кислородного взрыва нейтрофилов и гестационным возрастом (r = 0,67; p &lt; 0,001). Культивирование нейтрофилов недоношенных в присутствии гранулоцитарного колониестимулирующего фактора (Г-КСФ) приводит к 2,4–5-кратному повышению экспрессии CD16, CD32 и усилению кислородного взрыва.</p></sec><sec><title>Заключение</title><p>Заключение: недоношенные новорожденные характеризуются дисрегуляцией экспрессии Fc-gamma рецепторов и функциональной недостаточностью нейтрофилов. Г-КСФ модулирует экспрессию CD16 и CD32 на поверхности нейтрофилов и усиливает кислородный взрыв в них.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background: Premature infants have a high risk of bacterial infections facilitated by the immaturity of their immune system.</p></sec><sec><title>Objective</title><p>Objective: Our aim was to study the expression of Fc-gamma receptors of neutrophils and the possibility of its modulation in preterm infants (with a low, LBW, very low, VLBW and extremely low, ELBW, birth weight) with bacterial infection.</p></sec><sec><title>Methods</title><p>Methods: We examined cord blood samples, as well as peripheral venous blood samples of newborns taken at 28–30th day of life. The flow cytofluorometry method was used to determine the level of surface expression of Fc-gamma receptors by neutrophils (CD64, CD32, CD16), phagocytic activity and oxygen burst of granulocytes stimulated with fluorescently labelled Escherichia coli. Results: We examined blood samples of 10 full-term infants, 20 preterm infants with LBW, 18 preterm infants with VLBW and ELBW. CD64 expression in preterm infants at birth was higher than in full-term children and made 6.0 (5.3; 9.8), 7.1 (5.1; 11.5), and 4.27 (2.4; 5.8) MFI respectively (p = 0.013). CD16 expression in preterm infants, in contrast, was lower: 99.7 (71.3; 126.0) and 80.9 (58.7; 114.8), and 125.3 (95.5; 144.1) MFI respectively (p = 0.021). By the end of the 1st month of life, CD16 expression of peripheral blood neutrophils in preterm infants increased to 126.6 (110.1; 129.0) MFI in children with LBW and to 118.5 (99.5; 132.2) MFI — in children with VLBW/ELBW. CD32 expression in compared groups did not differ. A correlation between the intensity of the oxygen burst of neutrophils and gestational age was established (r = 0.67; p &lt;0.001). Neutrophil culture of preterm infants in the presence of granulocyte colony stimulating factor (G-CSF) results in a 2.4–5-fold increase in CD16, CD32 expression and enhancement of oxygen burst.</p></sec><sec><title>Conclusion</title><p>Conclusion: Preterm infants are characterized by deregulated expression of Fc-gamma receptors and functional impairment of neutrophils. G-CSF modulates the expression of CD16 and CD32 on the surface of neutrophils and enhances the oxygen burst in them.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>недоношенные</kwd><kwd>Fc-gamma рецепторы</kwd><kwd>фагоцитоз</kwd><kwd>кислородный взрыв</kwd><kwd>гранулоцитарный колониестимулирующий фактор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>preterm infants</kwd><kwd>Fc-gamma receptors</kwd><kwd>phagocytosis</kwd><kwd>oxygen burst</kwd><kwd>granulocyte colony stimulating factor</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">Дегтярёва М.В., Бирюкова Т.В., Володин Н.Н., и др.
