In 2012, there were registered 266,000 death cases and 528,000 new cases. At present, three HPV prophylactic vaccines were generated worldwide: bivalent Cervarix, quadrivalent Gardasil and nonavalent Gardasil-9. Examining such vaccines uncovered that they are able to induce anti-HPV antibody production against viral antigens lacked in vaccine formula. The mechanism of such crossneutralizing antibodies recognizing antigens derived from various HPV pathogenic types remains unknown. In our study we attempted to uncover putative basis underlying cross-reactive interaction between vaccine-induced antibodies and non-vaccine antigens by bioinformatical approaches, that might allow optimize generation of future candidate vaccines and obtain more effective polyvalent immunobiological preparations against HPV. We used amino acid sequences of L1 coat protein of four top high-risk oncogenic HPV types (16, 18, 31 and 45) in the study. Work sequences were retrieved from the International Data Base of NCBI (National Center for Biotechnology Information) and aligned by using Clustal Omega’ and BioEdit software. A search and analysis of distinct antigenic determinant (epitopes) were performed by using software suite BepiPred-2.0: Sequential B-Cell Epitope Predictor, DiscoTope 2.0 Server, and SYFPEITHI. Bioinformatics data revealed pronounced potential of cross-neutralizing vaccine-induced antibodies and non-vaccines antigens derived from high-risk pathogenic types HPV 16, 18, 31 and 45 owing to the similarity in antigenic determinants (epitopes). Common linear determinants for T- and B-cells were found in all four types of L1 protein counterparts. In addition, similar three-dimensional B-cell determinants were discovered in HPV16 L1 and HPV18 L1. Antigenic determinants derived from HPV16 L1 and HPV31 L1 exhibited most close similarity. Hence, while immunizing with HPV16 L1, a more pronounced and moderate cross-reactive antibodies interacting with HPV31 L1 as well as HPV18 L1 and HPV45 L1 antigens, respectively, should be expected. Inversely, immunization with HPV18 L1might elicit active and less efficient crossneutralizing response with HPV45 L1 as well as HPV16 L1 and HPV31 L1, respectively.</p><p> </p></abstract><trans-abstract xml:lang="ru"><p>Вирус папилломы человека (ВПЧ) относится к группе чрезвычайно распространенных вирусных инфекций, передающихся преимущественно половым путем. Вирус папилломы человека вызывает рак шейки матки, который является четвертой по распространенности формой рака у женщин. В 2012 г. было зафиксировано 266 тыс. смертей и 528 тыс. новых случаев. На сегодняшний день в мире созданы 3 профилактические вакцины против ВПЧ — двухвалентная «Церварикс», четырехвалентная «Гардасил» и девятивалентная «Гар-дасил-9». В процессе научного исследования этих вакцин выяснилось, что они способны индуцировать выработку антител к типам ВПЧ, антигенные белки которых не содержатся в составе вакцинного препарата. Причины такого перекрестного взаимодействия антител с антигенами, принадлежащими к разным патогенным типам ВПЧ, не определены. Данная работа посвящена попытке с помощью биоинформационных методов найти вероятное объяснение перекрестного взаимодействия антител к одним типам вирусов с антигенами других. Это даст возможность в будущем оптимизировать процесс создания кандидатных вакцин и получать более эффективные поливалентные иммунобиологические препараты против ВПЧ. В исследовании нами использованы аминокислотные последовательности белка L1 оболочки вирусов ВПЧ 4 наиболее онкогенных типов (16, 18, 31, 45). Последовательности были извлечены из международной базы данных NCBI (National Center for Biotechnology Information) и выровнены в программе «Clustal Omega» и в редакторе «BioEdit». Поиск и анализ потенциальных антигенных детерминант мы проводили с помощью программ «BepiPred-2.0: Sequential B-Cell Epitope Predictor», «DiscoTope 2.0 Server», «SYFPEITHI». Результаты биоинформационного исследования выявили значительный потенциал перекрестного взаимодействия антител с антигенами, принадлежащими к патогенным типам ВПЧ (16, 18, 31, 45) за счет сходства антигенных детерминант. Были обнаружены общие линейные детерминанты для Т-клеток и В-клеток у всех 4 типов вирусных белков L1. Также обнаружены сходные трехмерные антигенные детерминанты для В-клеток у ВПЧ16 L1 и ВПЧ18 L1. Антигенные детерминанты ВПЧ16 L1 и ВПЧ31 L1 более близки друг другу. Сходство наблюдается между ВПЧ18 L1 и ВПЧ45 L1. Поэтому при иммунизации ВПЧ16 L1 стоит ожидать более выраженного перекрестного взаимодействия антител с антигенами ВПЧ31 L1 и умеренного с ВПЧ18 L1 и ВПЧ45 L1. Напротив, при иммунизации ВПЧ18 L1 возможно активное перекрестное взаимодействие антител с антигенами ВПЧ45 L1 и менее выраженное с ВПЧ16 L1 и ВПЧ31 L1.</p></trans-abstract><kwd-group xml:lang="en"><kwd>аntigenic determinants</kwd><kwd>B-cell</kwd><kwd>HPV16L1</kwd><kwd>HPV18 L1</kwd><kwd>HPV31L1</kwd><kwd>HPV45 L1</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>антигенные детерминанты</kwd><kwd>В-клетки</kwd><kwd>ВПЧ16L1</kwd><kwd>ВПЧ18L1</kwd><kwd>ВПЧ31L1</kwd><kwd>ВПЧ45L1</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке РФФИ и Правительства Иркутской области в рамках научного проекта № 20-44-380001</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
