Гликаны обеспечивают влияние на различные эффекторные функции антитела, такие как антителозависимая клеточно-опосредованная цитотоксичность (ADCC), комплементзависимая цитотоксичность (CDC) и период полувыведения препарата. Способность достигнуть необходимого гликопрофиля терапевтического антитела за счет оптимизации условий культивирования будет способствовать как получению более эффективных препаратов, так и ускоренной разработке биоаналогов. По результатам проведенной работы установлено, что увеличение длительности культивирования приводит к снижению содержания галактоз; добавление регулятора афукоз EM-N-glycan regulator-2 (“Eminence”, Китай) приводит к снижению афукозилированных гликанов; коэкспресссия фермента Fut8 приводит к увеличению маннозных остатков. Также были апробированы различные подходы, обеспечивающие регуляцию содержания фукоз, манноз и галактоз в ходе процесса биосинтеза терапевтического антитела IgG1.</p></abstract><trans-abstract xml:lang="en"><p>The possibility to alter the glycosylation profile is an important prerequisite for the development of production technologies of therapeutic recombinant immunoglobulins. Glycans affect various effector functions of the antibody, such as antibody-dependent cell-mediated cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), and the drug half-life. The possibility to achieve the required glycosylation profile of a therapeutic antibody by optimizing cultivation conditions will facilitate both the creation of more effective drugs and accelerated development of biosimilars. The conducted study found that an increase in the cultivation duration leads to a decrease in the galactose content. The addition of the EM-N-glycan regulator-2 afucose regulator (Eminence, China) led to an decrease in the content of afucosylated glycans. The co-expression of the Fut8 enzyme led to an increase in mannose residues. Various approaches to regulation of fucose, mannose, and galactose contents during biosynthesis of IgG1 therapeutic antibody were tested.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>культура клеток СНО</kwd><kwd>профиль гликозилирования</kwd><kwd>рекомбинантные белки</kwd><kwd>терапевтические антитела</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CHO cell culture</kwd><kwd>glycosylation profile</kwd><kwd>recombinant proteins</kwd><kwd>therapeutic antibodies</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работы финансированы АО «ГЕНЕРИУМ»</funding-statement><funding-statement xml:lang="en">the work was funded by GENERIUM.</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">Гузов Е.А., Цирулева М.А., Исеркапов А.В., Тюкова А.П., Казин В.Н., Колышкин В.М., Игнатьев В.Г.
