Рекомбинантный белок flagG­protE является перспективной молекулой для создания кандидатной рекомбинантной вакцины против клещевого энцефалита благодаря способности к связыванию с МКА против природного белка Е вируса клещевого энцефалита. Проведено исследование антигенных детерминант двух рекомбинантных бел ­ ков protE и flagG­protE с помощью панели из восьми МКА. Рекомбинантный белок protE представлен белком оболочки вируса клещевого энцефалита, в рекомбинантном белке flagG­protE к нему добавлен домен flagG, кодирующий флагеллин G Salmonella typhi. Установлено, что изучаемые МКА связывались с эпитопами ре ­ комбинантного белка protE. Это свидетельствует о том, что исследуемый рекомбинантный белок имеет антигенную структуру, схожую с антигенной структурой нативного белка Е вируса клещевого энцефалита. При исследовании рекомбинантного белка flagG­protE по способности к связыванию с панелью из восьми МКА только пять из них были способны связываться с эпитопами рассматриваемого белка. МКА 4F6, 7F10 и 6B9 не узнавали соответствующий эпитоп рекомбинантного белка flagG­protE, тогда как в рекомбинантном белке protE эти эпитопы выявлялись успешно. Полученные данные свидетельствуют о том, что антигенная структура рекомбинантного protE­белка может быть изменена под влиянием флагеллинового домена, что, в свою очередь, может привести к недоступности некоторых антигенных детерминант. Это обстоятельство необходимо учитывать при конструировании рекомбинантных антигенов. Тем не менее принципиально важные районы в области пептида слияния и домена III оказались доступны для антител. Это должно обеспечить формирование нейтрализующих антител, а на личие полной аминокислотной последовательности белка Е в составе рекомбинантного белка будет индуцировать формирование Т­клеточного иммунного ответа. Появление нового поколения вакцин против клещевого энцефалита с более высоким уровнем безопасности и иммуногенности позволит усовершенствовать вакцинопрофилактику населения от клещевого  энцефалита.</p></abstract><trans-abstract xml:lang="en"><p>The present work describes the construction of the gene encoding the recombinant protein flagG­protE, its synthesis, purification and study. The recombinant flagG­protE protein is a promising molecule for developing a candidate recombinant vaccine against tickborne encephalitis by the ability to bind to monoclonal antibodies (MCA) against native protein E of tick­borne encephalitis virus. The antigenic determinants of two recombinant proteins were studied: protE and flagG­protE using a panel of 8 MCA. The recombinant protein protE comprises the tick­borne encephalitis virus envelope protein and the flagGprotE recombinant protein has an additional flagG domain encoding flagellin G of Salmonella typhi. It was found that the MCA tested revealed epitopes on the recombinant protein protE. This indicates that the investigated recombinant protein has an antigenic structure similar to the antigenic structure of the native tick­borne encephalitis virus protein E. In the study of the recombinant protein flagG­protE by the ability to bind a panel of 8 MCA, only five of them react with epitopes of the tested protein. MCA 4F6, 7F10, and 6B9 did not recognize the corresponding epitope in the recombinant flagG­protE protein, while in the recombinant protein protE, these epitopes were detected successfully. Our data indicate that the antigenic structure of recombinant protE­protein can be changed under the influence of the flagellin domain, which in turn can lead to the unavailability of some antigenic determinants. This fact must be taken into account when constructing recombinant molecules with antigenic properties. Nevertheless, the fundamentally important regions in the region of the fusion peptide and III domain are antigenically present on the surface of the recombinant protein. This should ensure the formation of neutralizing antibodies, and the presence of a complete amino acid sequence of protein E in the recombinant protein induces the formation of a T­cell immune response. The emergence of a new generation of vaccines against tick­borne encephalitis with a higher level of safety and immunogenicity will improve the vaccine prevention of the population from tick­borne encephalitis. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>флагеллин G</kwd><kwd>белок оболочки</kwd><kwd>адъювант</kwd><kwd>ВКЭ</kwd><kwd>иммуногенность</kwd><kwd>вакцина</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flagellin G</kwd><kwd>envelope protein</kwd><kwd>adjuvant</kwd><kwd>TBE</kwd><kwd>immunogenicity</kwd><kwd>vaccine</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">Amicizia D., Domnich A., Panatto D., Lai P.L., Cristina M.L., Avio U., Gasparini R.
