Methods. A comparative analysis of the immunomodulatory activity of yeast cell wall glycoproteins in a free and immobilized state was carried out. The dynamics of the process of accumulation of proinflammatory cytokines (IL6, IL8, and TNFa) in the extracellular medium after contact of human blood cells with glycoproteins was studied. The source of glycoproteins was the cell lysate of Saccharomyces cerevisiae. The glycoproteins were immobilized on a polyacrylamide gel in a copolymerization reaction. The study of the effectiveness of immobilized and free glycoproteins was carried out in in vitro experiments on the whole blood of practically healthy donors. The effectiveness was evaluated by the increase in the concentration of cytokines in the blood plasma after contact with glycoproteins compared to the baseline level, as well as by comparing the effect of polyacrylamide gel without a ligand and simply incubating blood cells with saline solution. Results. It was found that immobilized glycoproteins, as well as free ones, in contact with human peripheral blood lead to the activation of the synthesis of pro-inflammatory cytokines (IL6, IL8, and TNFa) by blood cells. The study revealed the peculiarities of cytokine synthesis depending on the form of contact of blood cells with the glycoprotein. It is shown that the rate of IL8 and TNFa synthesis is higher after blood contact with immobilized glycoproteins than with free-form glycoproteins.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования - изучить влияние химической иммобилизации гликопротеидов клеточной стенки дрожжей на их способность активировать продукцию цитокинов клетками периферической крови человека. Методы. Проведен сравнительный анализ иммуномодулирующей активности гликопротеидов клеточной стенки дрожжей в свободном и иммобилизированном состоянии. Исследована динамика процесса накопления провоспалительных цитокинов (IL6, IL8 и TNFa) во внеклеточной среде после контакта клеток крови человека с гликопротеидами. Источником гликопротеидов являлся клеточный лизат Saccharomyces cerevisiae. Иммобилизацию гликопротеидов проводили на полиакриламидном геле в реакции сополимеризации. Исследование эффективности иммобилизованных и свободных гликопротеидов проводили в экспериментах in vitro на цельной крови практически здоровых доноров. Эффективность оценивали по нарастанию концентрации цитокинов в плазме крови после контакта с гликопротеидами по сравнению с исходным уровнем, а также при сравнении с влиянием полиакриламидного геля без лиганда и просто инкубации клеток крови с физиологическим раствором. Результаты. Установлено, что иммобилизованные гликопротеиды, так же, как и свободные, при контакте с периферической кровью человека приводят к активации синтеза провоспалительных цитокинов (IL6, IL8 и TNFa) клетками крови. В исследовании выявлены особенности синтеза цитокинов в зависимости от формы контакта клеток крови с гликопротеидом. Показано, что скорость синтеза IL8 и TNFa выше после контакта крови с иммобилизованными гликопротеидами, чем с гликопротеидами в свободной форме.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cytokines</kwd><kwd>glycoproteins</kwd><kwd>yeast</kwd><kwd>interleukin-6</kwd><kwd>immunomodulators</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>цитокины</kwd><kwd>гликопротеиды</kwd><kwd>дрожжи</kwd><kwd>интерлейкин-6</kwd><kwd>иммуномодуляторы</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Беседнова Н.Н.
