A notable feature of tumors associated with EBV is their different incidence in various geographical regions, that, as suggested, related with mutational events in multiple loci of the EBV genome and its oncogene, the latent membrane protein 1 (LMP1), associated with the transforming potential of the virus. Given the multi-ethnic composition of Russian population and the diversity of geographical areas and conditions of their residence, it was relevant to examine the representatives of different geographical regions for the nature of their relationship with EBV. To solve this task the antibody response to locally circulating EBV strains, determined by indirect immunofluorescence, was studied in residents of the Central, North Caucasus and Far Eastern Federal Districts, represented by healthy individuals and patients with various head and neck tumors. The levels of antibody titers obtained were compared with the incidence rates of nasopharyngeal tumors (NPT) in population of above Districts. In order to determine possible structural modifications in LMP1 gene of EBV strains persisting in selected geographic regions, samples of the gene have been amplified from a biological material collected by “nested” PCR and sequenced. The results obtained have shown that levels of antibody response to EBV among representatives of the regions included in the study vary significantly. It was found that in residents of the Dagestan and the Chechen Republics, the inhabitants of the North Caucasus Federal District, the correlation between enhanced humoral response to EBV and increased incidence of NPT was detected. Since among NPT the EBV-associated form of nasopharyngeal carcinoma (NPCEBV) is dominated, the findings allow us to suggest that the population of these Republics have genetic predisposition to increased EBV replication and, consequently, an elevated incidence of NPCEBV. The study also showed that representatives of the regions tested are infected with EBV strains, LMP1 variants of which such as B95.8, China 1, Med+, Med– and NC, are known in the literature. However, LMP1 variant, specifically associated with NPCEBV, has not been identified. This study showed for the first time the genetic heterogeneity of EBV strains circulating among population of different geographical regions of the country, and the existence of correlation between antibody response to EBV and the incidence of nasopharyngeal tumors, including NPCEBV.</p></abstract><trans-abstract xml:lang="ru"><p>Известно, что вирус Эпштейна–Барр (ВЭБ), широко распространенный в человеческой популяции, является также этиологическим агентом для широкого спектра злокачественных новообразований. Примечательной особенностью опухолей, ассоциированных с ВЭБ, является их отличающийся уровень заболеваемости в различных географических регионах. На уровни заболеваемости ВЭБ-ассоциированными патологиями оказывает влияние вариабельность многочисленных локусов генома вируса и его онкогена — латентного мембранного белка 1 (LMP1), с которым связан трансформирующий потенциал вируса. Учитывая многонациональный состав населения России, разнообразие географических зон и условий его проживания, представлялось актуальным изучить у жителей из разных географических регионов страны характер их взаимоотношения с ВЭБ. Для решения поставленной задачи антительный ответ к локально циркулирующим штаммам ВЭБ, определяемый методом непрямой иммунофлуоресценции, изучали у представителей Цент рального, Северо-Кавказского и Дальневосточного федеральных округов, здоровых и больных различными опухолями головы и шеи. Полученные титры антител сопоставляли с показателями заболеваемости в этих же округах опухолями носоглотки (ОНГ). С целью выяснения наличия структурных модификаций в гене LMP1 у штаммов ВЭБ, циркулирующих в изучаемых географических регионах, указанный ген из биологического материала, собранного от представителей изучаемых групп, был амплифицирован методом «гнездной» ПЦР и секвенирован. Исследования показали, что уровни гуморального ответа к ВЭБ у представителей, вошедших в исследование регионов, существенно разнятся. При этом было обнаружено, что у жителей Республики Дагестан и Чеченской Республики (представителей Северо-Кавказского федерального округа), имеет место корреляция между усиленным гуморальным ответом к ВЭБ и повышенной заболеваемостью ОНГ. Поскольку среди ОНГ доминирует ВЭБ-ассоциированная форма рака носоглотки (РНГВЭБ), то полученные данные позволяют предположить наличие у населения этих республик генетической предрасположенности к повышенной репликации ВЭБ и, соответственно, к повышенной заболеваемости РНГВЭБ. Исследование также показало, что представители изученных регионов инфицированы штаммами ВЭБ, образцы LMP1 которых относятся к известным в литературе вариантам, таким как B95.8, China 1, Med+, Med– и NC, но вариант LMP1, специ фически ассоциированный с РНГВЭБ, выявлен не был. Проведенное исследование впервые выявило генетическую разнородность штаммов ВЭБ, циркулирующих среди населения различных географических регионов страны, и наличие корреляции между уровнями гуморального ответа к ВЭБ и заболеваемостью опухолями носоглотки, включая РНГВЭБ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Epstein–Barr virus</kwd><kwd>antibody response</kwd><kwd>nasopharyngeal cancer</kwd><kwd>LMP1 oncogene</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вирус Эпштейна–Барр</kwd><kwd>гуморальный ответ</kwd><kwd>рак носоглотки</kwd><kwd>онкоген LMP1</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
