Определение тропизма ВИЧ проводилось путем секвенирования V3 петли гена gp120. Установлена более выраженная экспрессия маркеров активации у пациентов, инфицированных R5-тропными вариантами вируса по сравнению с пациентами, инфицированными не R5-тропными вирусами. Выявлен различный характер экспрессии CCR5 и CXCR4 на лимфоцитах крови при формировании стадии СПИДа в зависимости от тропизма вируса, что позволяет предположить о существовании различных механизмов формирования иммуносупрессии, связанных с вирусным тропизмом. В изучаемой группе пациентов не обнаружено корреляции между клиническими проявлениями ВИЧ-инфекции, включая наличие СПИД, и тропизмом вируса.</p></abstract><trans-abstract xml:lang="en"><p>Analysis of clinical, immunological and epidemiological features of HIV infection in 57 patients infected by subtype A HIV-1 in 98,2% cases has been done in dependence on viral tropism. Detection of HIV tropism was performed by sequencing of V3 loop of gp120 gene. It was revealed that patients infected by R5-tropic HIV had more expressed immunity activation markers on blood lymphocytes in comparison with ones infected by non-R5-tropic HIV The different profile of CCR5 and CXCR4 expression on blood lymphocytes were detected in patients with AIDS in dependence on tropism that seem to associate with existing of different mechanism of immunosuppression formation in different viral tropism. Correlation between clinical symptoms including presence of AIDS and viral tropism has not been revealed in studied group.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ВИЧ-1</kwd><kwd>тропизм</kwd><kwd>корецептор</kwd><kwd>CCR5</kwd><kwd>CXCR4</kwd><kwd>HIV-1</kwd><kwd>tropism</kwd><kwd>coreceptor</kwd><kwd>CCR5</kwd><kwd>CXCR4</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">Levy J.A.
