In result of research we obtained new data on the phenotypic features of NG subpopulations carrying the CD64, CD32, CD16 and CD11b molecules in newborns and children compared to the group of adult healthy individuals. It has been established that in the peripheral blood of healthy full-term newborns, conditionally healthy children of different age and conditionally healthy adults there are two main subpopulations of circulate NG – major with СD64–CD16+CD32+CD11b+ phenotype and minor СD64+CD16+CD32+CD11b+ phenotype, different receptor expression density noted in both subpopulations. It was shown that each of the studied groups has its own phenotypic profile, possibly optimal for performing NG eff ector functions. In newborns are identified phenotypes СD64–CD16<sup>dim</sup>CD32<sup>dim</sup>CD11<sup>bbright</sup>NG and СD64<sup>dim</sup>CD16<sup>mid</sup>CD32<sup>bright</sup> CD11<sup>bbright</sup>NG, in children 2–4 years old СD64–CD16<sup>bright</sup>CD32<sup>dim</sup>CD11<sup>bbright</sup>NG and СD64<sup>mid</sup>CD16<sup>bright</sup> CD32<sup>dim</sup>CD11<sup>bbright</sup> NG, in children 5–9 years old СD64–CD16<sup>mid</sup>CD32<sup>dim</sup>CD11<sup>bdim</sup>NG and СD64<sup>dim</sup> CD16<sup>bright</sup>CD32<sup>mid</sup>CD11<sup>bdim</sup>NG, in conditionally healthy adults СD64–CD16<sup>mid</sup>CD32<sup>dim</sup>CD11<sup>bdim</sup>NG and СD64<sup>bright</sup>CD16<sup>dim</sup>CD32<sup>mid</sup>CD11<sup>bdim</sup>NG. Study shown that the NG of newborns and children of different age groups have a similar expression density of the CD64, CD16, CD32, CD11b receptors in major and minor subpopulations, NG subpopulations of healthy adults are equipped differently. The study of receptors in physiological according to age-related features is necessary for the correct interpretation of the transformation of the phenotype, changes in surface receptors expression in various pathological conditions. </p></abstract><trans-abstract xml:lang="ru"><p>Нейтрофильные гранулоциты (НГ) с различной рецепторной оснащенностью, представляют собой гетерогенные субпопуляции отличающиеся по своим биологическим свойствам и роли в патогенезе иммунозависимых заболеваний. В результате исследований нами получены новые данные о фенотипических особенностях субпопуляций НГ, несущих молекулы CD64, CD32, CD16 и CD11b, характерных для новорожденных и детей по сравнению с группой условно-здоровых взрослых субъектов. Установлено, что в периферической крови здоровых доношенных новорожденных, услов ноздо ровых детей разных возрастных групп и взрослых циркулируют две основные субпопуляции НГ – мажорная с фенотипом СD64–CD16⁺CD32⁺CD11b⁺ и минорная СD64⁺CD16⁺CD32⁺CD11b⁺ с разной плотностью экспрессии рецепторов. Показано, что для каждой из исследуемых групп характерен свой фенотипический профиль, возможно оптимальный, для выполнения НГ эффекторных функций. Так у новорожденных определены субпопуляции с фенотипами СD64–CD16<sup>dim</sup>CD32<sup>dim</sup>CD11<sup>bbright</sup>НГ и СD64<sup>dim</sup>CD16<sup>mid</sup>CD32<sup>bright</sup>CD11<sup>bbright</sup>НГ; у детей 2–4 лет СD64–CD16<sup>bright</sup>CD32<sup>dim</sup>CD11<sup>bbright</sup>НГ и СD64<sup>mid</sup>CD16<sup>bright</sup>CD32<sup>dim</sup>CD11<sup>bbright</sup>НГ; у детей 5–9 лет СD64–CD16<sup>mid</sup>CD32<sup>dim</sup>CD11<sup>bdim</sup>НГ и СD64<sup>dim</sup> CD16<sup>bright</sup>CD32<sup>mid</sup>CD11<sup>bdim</sup>НГ и у группы здоровых взрослых СD64–CD16<sup>mid</sup>CD32<sup>dim</sup>CD11<sup>bdim</sup>НГ и СD64<sup>bright</sup>CD16<sup>dim</sup>CD32<sup>mid</sup>CD11<sup>bdim</sup>НГ. Установлено, что НГ новорожденных и детей разных возрастных групп имеют схожую плотность экспрессии рецепторов СD64, CD16, CD32, CD11b на мажорной и минорная субпопуляциях, в то время как субпопуляции НГ здоровых взрослых оснащены по-разному. Изучение рецепторов при физиологических состояниях с учетом возрастных особенностей, необходимо для правильной интерпретации трансформации фенотипа, изменения поверхностной экспрессии при различных патологических состояниях. </p></trans-abstract><kwd-group xml:lang="en"><kwd>neutrophilic granulocytes</kwd><kwd>phenotype</kwd><kwd>subset</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нейтрофильные гранулоциты</kwd><kwd>фенотип</kwd><kwd>субпопуляции</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
