Количественный анализ некоторых групп микроорганизмов, выделенных из атеро-склеротически изменённых коронарных артерий больных в зависимости от ASP299GLY полиморфизма гена TLR4

Abstract

The estimation data of contamination by separate groups of microorganisms and dependence of the microbial content level upon TLR4 gene 896A/G polymorphism in 20 samples of atherosclerotic lesions in coronary arteries has been presented. The presence of TLR4 gene polymorphic allele G in the individual genotype determines the increased contamination of atherosclerotic plaque tissues by the representatives of the following genera: Lactobacillus sp., Enterobacterium sp., Sneathia sp. /Leptotrihia sp. /Fusobacterium sp., Mobiluncus sp. /Corynebacterium sp., Peptostreptococcus sp. The emergence of new correlation pairs with participation of Lachnobacterium sp. /Corynebacterium sp. among the carriers of G allele has been revealed via the intragroup correlation analysis. The obtained results confirm the possible involvement of the represented groups of microorganisms in the pathogenesis of atherosclerosis and the role of the TLR4 gene polymorphic variant G in the increased microbial contamination of the coronary arteries tissues.
