The dynamics of gene expression of two proteins, TLR9 (one of the key receptors recognizing CpG repeats of herpes virus DNA) and β-defensin 2 (antibacterial peptide), was studied on the model of herpetic keratitis in C57Bl/6 and BALB/c mice. New data on differences in TLR9 gene expression in mice of the two strains infected with the virus were obtained. Reduced TLR9 gene expression in the cornea of C57Bl/6 mice was associated with their high sensitivity to infection caused by herpes simplex 1 virus.
ИсследованИе ассоцИацИИ полИморфных маркеров генов TLR2 И TLR9 с преждевременнымИ родамИ И внутрИутробным ИнфИцИрованИемГанковская О.А. ГУ НИИ вакцин и сывороток им. И.И. Мечникова РАМН, Москва ГОУ ВПО РГМУ Росздрава, МоскваРезюме. В последние годы активно изучается роль генетических факторов в формировании пол-ноценных механизмов врожденного иммунитета. TLRs играет большую роль в развитии патологии инфекционного генеза при беременности. Цель данного исследования -изучение ассоциации по-лиморфизмов Arg677Trp, Arg753Gln в гене TLR2 и A2848G в гене TLR9 с преждевременными рода-ми инфекционного генеза и внутриутробным инфицированием в русской популяции на территории г. Москвы. Полиморфные маркеры Arg677Trp, Arg753Gln в гене TLR2 были определены в клиниче-ском материале с помощью ПЦР-ПДРФ (с использованием рестриктазы AciI), полиморфный мар-кер A2848G в гене TLR9 был определен с помощью ПЦР в режиме реального времени в присутствии TaqMan зондов. Показано, что аллель Arg полиморфного маркера Arg753Gln гена TLR2 был ассо-циирован с внутриутробной инфекцией. Другой аллель А полиморфного маркера A2848G гена TLR9 ассоциирован со срочными родами при урогенитальной инфекции. Таким образом, полиморфный маркер A2848G можно расценивать в качестве протективного.Ключевые слова: врожденный иммунитет, Toll-подобные рецепторы, полиморфизм, преждевременные роды, урогениальная инфекция. Gankovskaya O.A. AssociAtion studies between polymorphic mArkers tlr2 And tlr9, pre-term delivery And intrAuterine infectionsАbstract. During last years, a role of genetic factors in maturation of innate immunity functions was actively studied. It is known, that some SNP in TLR9 and TLR2 genes are known to be associated with development of infection in pregnancy. However, interrelations of various TLR-mediated anti-infectious mechanisms with genetic factors in pregnant women were poorly studied. The aim of present study was to evaluate associations between the following SNPs: Arg677Trp, Arg753Gln of TLR2 gene, A2848G SNP of TLR9 gene, and frequencies of pre-term birth complicated by infections in Russian population of Moscow City. SNPs Arg677Trp, Arg753Gln in TLR2 gene have been studied in a clinical material by means of PCR-RFLP analysis, using AciI restrictase. A2848G polymorphic marker in TLR9 gene was assessed by real-time PCR, employing TaqMan probes. It has been shown, that Arg allele of Arg753Gln TLR2 gene was associated with urogenital infections. When studying A2848G polymorphism in TLR9 gene, the A Allele was associated with normal delivery, thus assuming the A2848G polymorphic marker as a protective one. (Med.
