Экспериментальный аутоиммунный энцефаломиелит (далее - ЭАЭ) является его широко используемой животной моделью. Патология РС-ЭАЭ в значительной степени модулируется микроглией, резидентными иммунными компетентными клетками ЦНС. Цель исследования - на животной модели РС - острой и хронической форме ЭАЭ, изучить динамику изменений микроглиальной популяции спинного мозга у мышей методом иммунофлуоресцентного анализа. Было обнаружено, что Iba1+ клетки с морфологией покоящейся микроглии равномерно распределены в спинном мозге контрольных мышей. В отличие от нормы, активированные микроглиоциты были более выражены в сером веществе спинного мозга мышей с острой формой ЭАЭ. Крупные микроглиальные клетки образовывали скопления в сером веществе - «конгломераты», предположительно атакуя другие клетки спинного мозга. В спинном мозге мышей с хронической формой ЭАЭ наблюдалась другая картина распределения микроглиальной популяции - клетки локализовались в белом веществе, предположительно в местах демиелинизации. Таким образом, при острой форме ЭАЭ в спинном мозге мышей происходит активация и пролиферация микроглиоцитов, преимущественно в сером веществе. Количество активированной микроглии снижается в хронической стадии ЭАЭ с локализацией в зонах демиелинизации в белом веществе. Полученные результаты указывают на то, что морфофункциональные изменения микроглиальных клеток спинного мозга мышей в условиях развития ЭАЭ и динамика ответов микроглии в данных условиях может в значительной степени определять феноменологию патофизиологических процессов при ЭАЭ. Следовательно, понимание участия микроглии в РС может открыть новые перспективные пути терапевтического вмешательства.</p></abstract><trans-abstract xml:lang="en"><p>Multiple sclerosis (MS) is the most common autoimmune disease of the central nervous system (CNS). Experimental autoimmune encephalomyelitis (EAE) is its widely used corresponding animal model. MS/EAE pathology are substantially modulated by microglia, the resident immune competent cells of the CNS. The aim - on acute and chronic form of EAE in mice, to study the dynamics of changes in the microglial population of the spinal cord by immunofluorescence analysis. We used activated microglia marker Iba1+ to characterize distribution of microglia/macrophages in spinal cord of normal mice and mice with acute and chronic model of EAE. We found that Iba1+ cells with morphology of resting microglia equally distributed in the normal spinal cord of control mice. In contrast to controls, microglia activation was more pronounced in the grey matter of acute spinal cords compare to the white matter. Amoeboid microglial cells formed some form of aggregations in the gray matter - «conglomerates», presumably attacking other cells of the spinal cord. In chronic spinal cord, we observed different pattern of distribution of microglial population - the cells localized in the white matter, presumably in the sites of demyelination. Hereby, in spinal cord of mice with acute form of EAE, activation and proliferation of microglial cells take place, mainly in the gray matter. The amount of activated microglia decreases in the chronic stage of the EAE with localization in the areas of demyelination in the white matter. The obtained results indicate that the morphological-functional changes in the microglial cells of the mouse spinal cord under the conditions of development of the EAE and the dynamics of the microglia responses under these conditions might determine the phenomenology of pathophysiological processes in the EAE. Hence, understanding microglia involvement in MS offers new promising paths for therapeutic intervention.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микроглия</kwd><kwd>экспериментальный аллергический энцефаломиелит</kwd><kwd>спинной мозг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Iba1+-клетки</kwd><kwd>microglia</kwd><kwd>experimental allergic encephalomyelitis</kwd><kwd>spinal cord</kwd><kwd>Iba1+-cells</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">Dendrou CA, Fugger L, Friese MA.
