При этом в развитии атеросклероза и ремоделирования сосудов особо важное значение имеют компоненты тканевых, локальных РАС. В данном исследовании мы изучали плотность рецепторов ангиотензина II 1-го типа (AT1R), как маркера активности РАС, в гладкомышечных клетках сосудов (ГМКС) у пациентов с мультифокальным атеросклерозом и артериальной гипертензией. Оказалось, что только у 50% пациентов наблюдалась высокая плотность AT1R в ГМКС, при этом в маммарных артериях, наименее подверженных атеросклерозу, плотность AT1R не отличалась от таковой в сосудах, пораженных атеросклерозом. Механизмы, определяющие неоднородность активности тканевых компонентов РАС у пациентов с атеросклерозом, требуют дальнейшего изучения.</p></abstract><trans-abstract xml:lang="en"><p>Local expression of rennin-angiotensin system (RAS) components significantly increases in patients with arterial hypertension and atherosclerosis with or without elevation of RAS activity in the blood. Our objectives was to assessment and compare the expression level of angiotensin II type 1 receptor in the smooth muscle cells in arteries of patients with multifocal atherosclerosis and the role of local angiotensin II receptor type 1 (AT1R) expression in the disease progression. The study results suggest that the tissue RAS activity increases inhomogeneously among patients. It was interestly that AT1R expression levels in intact arteries does not differ of those in atherosclerotic arteries. Most of patients had expression of angiotensin II type 1 receptor in smooth muscle of arteries; strong elevation had 43,8% — 50,0%. Our study suggest of role of local RAS activity, but we proposed existence of another than only angiotensin II type 1 receptor mechanisms of low or high susceptibility of arteries to atherosclerosis in patient with multifocal atherosclerosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ренин-ангиотензиновая система</kwd><kwd>рецептор ангиотензина II 1-го типа</kwd><kwd>мультифокальный атеросклероз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>renin-angiotensin system</kwd><kwd>angiotensin II receptor type 1</kwd><kwd>multifocal atherosclerosis</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">De Giusti VC, Ciancio MC, Orlowski A, Aiello EA.
