Хроническая обструктивная болезнь легких (ХОБЛ) – широко распространенное заболевание, занимающее третье место среди причин смертности в глобальных масштабах. Для этой патологии может быть характерно нарушение фагоцитоза и эффероцитоза, что способствует хроническому воспалению и повышает риск бактериальных инфекций дыхательных путей. Ранее нами была установлена гиперэкспрессия каналов TRPV1 в моноцитах и макрофагах пациентов с ХОБЛ.</p></sec><sec><title>   Цель</title><p>   Цель. Изучить фагоцитарную активность моноцитов у больных ХОБЛ и оценить влияние агониста TRPV1 – капсаицина – на эффективность фагоцитоза in vitro.</p></sec><sec><title>   Материалы и методы</title><p>   Материалы и методы. В исследование было включено 42 больных ХОБЛ различной степени тяжести и 11 лиц, не имевших бронхиальной обструкции (контрольная группа). Фагоцитарную активность моноцитов тестировали методом проточной цитометрии с использованием компетентных клеток E. coli XL1-Blue, трансформированных плазмидойpTurboGFP-B.</p></sec><sec><title>   Результаты</title><p>   Результаты. Результаты исследования показали отсутствие статистически значимых различий в исходной фагоцитарной активности моноцитов между пациентами с ХОБЛ и здоровыми добровольцами (78,6 (73,4–87,4) % против 84,8 (65,6–88,3) %, p = 0,77). Воздействие капсаицина вызывало значимое угнетение фагоцитоза E. coli в обеих группах: у больных ХОБЛ (с 78,6 (73,4–87,4) % до 64,4 (55,9–71,8) %, p &lt; 0,001) и в контрольной группе (с 84,8 (65,6–88,3) % до 71,4 (65,7–74,0) %, p &lt; 0,01). При этом степень подавления фагоцитоза под действием капсаицина была выше у пациентов с ХОБЛ по сравнению с контролем (–17,5 (–24,9;–13,1) % против –9,4 (–16,4;–3,3) %, p = 0,03). Тем не менее, после экспозиции с капсаицином достоверные различия в уровне фагоцитоза между исследуемыми группами также отсутствовали.</p></sec><sec><title>   Заключение</title><p>   Заключение. Таким образом, наши данные свидетельствуют о том, что моноциты пациентов с ХОБЛ не демонстрируют значимых отклонений в фагоцитарной активности in vitro. Стимуляция TRPV1 капсаицином приводит к статистически значимому угнетению фагоцитоза E. coli в обеих группах, причем более выраженное снижение наблюдается при ХОБЛ, что, вероятно, подтверждает роль этого рецептора в модуляции иммунных функций моноцитов, учитывая повышенную экспрессию TRPV1 и наличие эндогенных активирующих стимулов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Introduction</title><p>   Introduction. Chronic obstructive pulmonary disease (COPD) is a common disorder and the third leading cause of death globally. It may be characterized by impaired phagocytosis and efferocytosis, which contributes to chronic nflammation and increases the risk of bacterial respiratory infections. Previously, we established hyperexpression of TRPV1 channels in monocytes and macrophages of patients with COPD.</p></sec><sec><title>   Aim</title><p>   Aim. To study the phagocytic activity of monocytes in patients with COPD and to evaluate the effect of the TRPV1 agonist capsaicin on the efficiency of phagocytosis in vitro.</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods. The study included 42 patients with COPD of varying severity and 11 control subjects. Phagocytic activity of monocytes was tested by flow cytometry using competent E. coli XL1-Blue cells transformed with pTurboGFP-B plasmid.</p></sec><sec><title>   Results</title><p>   Results. The results of the study showed no statistically significant differences in the initial phagocytic activity of monocytes between patients with COPD and healthy volunteers (78.6 (73.4–87.4) % vs. 84.8 (65.6–88.3) %, p = 0.77). Exposure to capsaicin caused significant inhibition of E. coli phagocytosis in both groups: in COPD patients (from 78.6 (73.4–87.4) % to 64.4 (55.9–71.8) %, p &lt; 0.001) and in the control group (from 84.8 (65.6–88.3) % to 71.4 (65.7–74.0) %, p &lt; 0.01). Moreover, the degree of phagocytosis suppression under the influence of capsaicin was higher in COPD patients compared to the control (–17.5 (–24.9; –13.1)% vs. –9.4 (–16.4; –3.3)%, p = 0.03). However, after exposure to capsaicin, there were also no significant differences in the level of phagocytosis between the study groups.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. Thus, our data indicate that monocytes from COPD patients do not exhibit significant abnormalities in phagocytic activity in vitro. Stimulation of TRPV1 with capsaicin results in statistically significant inhibition of E. coli phagocytosis in both groups, with a more pronounced decrease observed in COPD, which confirms the role of this receptor in modulating the immune functions of monocytes, given the increased expression of TRPV1 and the presence of endogenous activating stimuli..</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>TRP-каналы</kwd><kwd>моноциты</kwd><kwd>фагоцитоз</kwd><kwd>ХОБЛ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>TRP channels</kwd><kwd>monocytes</kwd><kwd>phagocytosis</kwd><kwd>COPD</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках программы фундаментальных исследований Министерства науки и высшего образования РФ (FGWF-2025-0009)</funding-statement><funding-statement xml:lang="en">This study was supported by the Ministry of Science and Higher Education of the Russian Federation under the Program for Basic Research (FGWF-2025-0009)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">GBD 2021 Forecasting Collaborators.
