Изучение влияния флавоноидов на фагоцитарную активность профессиональных фагоцитов представляется достаточно перспективным направлением для их дальнейшего использования в качестве фармакологического (терапевтического) агента. К наиболее распространенным представителям флавоноидов с плейотропным действием относятся кверцетин и лютеолин. Углубленное изучение и понимание иммунотропных механизмов (в том числе на примере регуляции фагоцитоза) является необходимым условием для проведения адекватной фармакотерапии при инфекционных процессах, воспалительных заболеваниях неспецифической этиологии, аутоиммунных и онкологических состояниях. Цель работы – изучить влияние флавоноидов на фагоцитарную активность профессиональных фагоцитов (нейтрофилов) в системе in vitro. В работе использован биологический материал (венозная кровь) 30 практически здоровых человек (взрослые n = 15, дети n = 15). Исследование выполнено в соответствии с установленными международными правилами. В опытные пробы вносили 0,5 мг/л Luteolin (содержание основного вещества ≥ 98%) и Quercetin (содержание основного вещества ≥  95%) и инкубировали 20 мин при 37 °С. Процент фагоцитоза, фагоцитарное число (количество поглощенных формалинизированных эритроцитов барана одной клеткой нейтрофила) определяли с помощью световой микроскопии в контрольных и опытных образцах. В системе in vitro отмечен однонаправленный характер угнетения фагоцитоза кверцетином и лютеолином. Идентифицировано статистически значимое (p &lt; 0,05) ослабление на 10% интенсивности фагоцитоза в опытных образцах крови, полученной от взрослых пациентов, относительно контрольных значений. При добавлении кверцетина и лютеолина в пробы крови, полученной от детей, отмечено статистически значимое (p &lt; 0,05) снижение на 30% фагоцитоза по сравнению с контрольными величинами. Вместе с тем среднее значение процента фагоцитоза и фагоцитарного числа в образцах крови после добавления флавоноидов регистрировались в диапазоне референтных значений, что демонстрирует адекватность и физиологичность угнетения чрезмерной агрессивности компартментов врожденного иммунитета кверцетином и лютеолином. Установлено, что в указанной концентрации более выраженное супрессорное действие флавоноиды оказывали на фагоцитарную активность у детей. Моделирование иммунного ответа на примере индикаторных показателей фагоцитоза с его верификацией на экспериментальных моделях in vitro на нейтрофилах, полученных у практически здоровых взрослых и детей, позволяет расширить понимание механизма иммунотропного эффекта флавоноидов кверцетина и лютеолина для задач коррекции иммунопатологических состояний.</p></abstract><trans-abstract xml:lang="en"><p>Polyphenols exert a wide range of biological effects, including immunomodulatory action. Studying the effects of flavonoids on phagocytic activity of specialized phagocytic cells seems to be a rather promising direction for their further usage as pharmacological (therapeutic) agents. Quercetin and luteolin are the most commonly studied flavonoid substances with pleiotropic action. In-depth study and understanding of immunotropic mechanisms (e.g., regulation of phagocytosis) is a prerequisite for adequate pharmacotherapy in infectious conditions, nonspecific inflammatory diseases, autoimmune and oncological disorders. The aim of our work is to study the effect of flavonoids upon phagocytic activity of professional phagocytes (neutrophils) using an in vitro test system. The biological material (venous blood) from 30 practically healthy people (adults n = 15, children n = 15) was used in the present work. The study was carried out in accordance with established international regulations. 0.5 mg/L of Luteolin (basic substance content ≥ 98%) and Quercetin (basic substance content ≥ 95%) were added to experimental samples and incubated for 20 min at 37 °С. The percentage of phagocytosis, phagocytic number (mean number of formalin-treated sheep erythrocytes engulfed per one neutrophil) was determined in control and experimental samples using light microscopy. The unidirectional nature of phagocytosis inhibition by quercetin and luteolin was noted in the test experiments. A statistically significant (p &lt; 0.05) decrease in the phagocytosis intensity by 10% was shown in experimental blood samples obtained from adult patients compared with control values. When quercetin and luteolin were added to blood samples obtained from children, a statistically significant (p &lt; 0.05) decrease in phagocytosis by 30% was noted against control values. At the same time, the mean percentage of phagocytosis and phagocytic number in blood samples after the addition of flavonoids were found to be in the range of reference values, thus suggesting adequacy and physiological suppression of excessive activities of innate immunity compartments by quercetin and luteolin. At this concentration, the flavonoids were found to exert a more pronounced suppressive effect on phagocytic activity in children. Modeling of immune response using the phagocytosis indices assayed in experimental in vitro models with neutrophils from practically healthy adults and children enables us to expand the knowledge of mechanisms underlying the immunotropic effects of flavonoids (quercetin and luteolin), in order to correct immunopathological conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>иммуномодулирующая активность</kwd><kwd>кверцетин</kwd><kwd>лютеолин</kwd><kwd>фагоцитоз</kwd><kwd>нейтрофилы</kwd><kwd>эксперимент in vitro</kwd></kwd-group><kwd-group xml:lang="en"><kwd>immunomodulatory activity</kwd><kwd>quercetin</kwd><kwd>luteolin</kwd><kwd>phagocytosis</kwd><kwd>neutrophils</kwd><kwd>in vitro study</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">Кетлинский С.А., Калинина Н.М.
