Показано, что в крови больных детей с полиморфизмом гена Toll-4 рецептора уменьшается синтез цитокинов IL-1β, ФНО-α и увеличивается содержание IL-1RA по сравнению с группой больных детей без аномальных нарушений в сигнальных рецепторах. При полиморфизме в генах Toll-6 рецептора уменьшается концентрация цитокинов IL-1β, IL-8, ФНО-α и IL-10. Концентрация IL-1RA увеличивается у генотипов Pro/Pro и Gly/Gly по сравнению с группой пациентов без полиморфных изменений в соответствующих рецепторах. Генетические нарушения в синтезе цитокинов при полиморфизме генов Toll-4 (Asp299Gly) и Toll-6 (Ser249Pro) рецепторов являются одной из причин несостоятельности противовирусной защиты у детей, часто болеющих ОРВИ.</p></abstract><trans-abstract xml:lang="en"><p>   The article analyzes the role of polymorphism of Toll-4 (Asp299Gly) and Toll-6 (Ser249Pro) receptor genes in the development of low antiviral protection in children with frequent episodes of acute respiratory infections. It is shown that the synthesis of cytokines IL-1-β, TNF-α decrease in the blood of patients with Toll-4 receptor gene polymorphism and IL-1RA content is increased in comparison with the group of diseased children without abnormal disturbances in signal receptors. Polymorphism in the Toll-6 receptor genes decreases the concentration of cytokines IL-1β, IL-8, TNF-α and IL-10. The concentration of IL-1RA is increased in Pro / Pro and Gly / Gly genotypes compared to the group of patients without polymorphic changes in the corresponding receptors. Genetic disorders in the synthesis of cytokines in the polymorphism of the Toll-4 (Asp299Gly) and Toll-6 (Ser249Pro) receptors are one of the reasons for the failure of antiviral protection in children who often have ARI.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ОРВИ</kwd><kwd>TLR</kwd><kwd>полиморфизм</kwd><kwd>цитокины</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute respiratory viral infection</kwd><kwd>TLR</kwd><kwd>polymorphism</kwd><kwd>cytokines</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">Борисова В.Н.
