Изучить особенности морфогенеза и эпителиального восстановления (репарации) слизистой оболочки желудка при хроническом гастрите у пациентов с синдромом Марфана и марфаноподобными состояниями. Материалы и методы. Проведены гистологическая оценка и иммуногистохимический анализ экспрессии антител к α-актину гладких миоцитов (α-SMA), коллагену III типа и трансформирующему фактору роста β (TGFβ) в слизистой оболочке желудка у 50 пациентов с наследственными нарушениями соединительной ткани в возрасте от 17 до 41 года. Результаты. Установлено, что фоновые наследственные нарушения соединительной ткани (синдром Марфана и марфаноподобные состояния) являются неблагоприятным фоновым фактором течения хронического гастрита в виде разнонаправленных прогредиентных атрофических и фибротических процессов в слизистой оболочке желудка. Доказана ключевая роль расторможенной TGFβ активности в фиброгенез-зависимой активации субэпителиальных миофибробластов (α-SMA+) c развитием особого морфогенетического варианта (патоморфогенеза) раннего хронического атрофического мультифокального гастрита в молодом возрасте.</p></abstract><trans-abstract xml:lang="en"><p>The aim was to explore the features of epithelial morphogenesis and reparation of gastric mucosa in chronic gastritis in patients with Marfan syndrome and Marfan -like states. Materials and methods. A histological evaluation and immunohistochemical analysis of the expression of antibodies against α-actin smooth muscle (α-SMA), collagen type III and transforming growth factor β (TGFβ) in the gastric mucosa in 50 patients with hereditary disorders of connective tissue between the ages of 17 to 41 years were performed. Results. In patients with Marfan syndrome and marfan-like states chronic gastritis was an unfavorable factor for the progression of the background atrophic and fibrotic processes in the gastric mucosa. It proved a key role disinhibited to TGFβ activity-dependent activation of fibrogenesis of subepithelial myofibroblasts (α-SMA +) with the development of a special morphogenetic variants of early chronic atrophic multifocal gastritis at a young age.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический гастрит</kwd><kwd>атрофия слизистой оболочки желудка</kwd><kwd>синдром Марфана</kwd><kwd>марфаноподобные состояния</kwd><kwd>миофибробласты</kwd><kwd>трансформирующий фактор роста β (TGFβ)</kwd><kwd>Наследственные нарушения соединительной ткани</kwd><kwd>коллаген III типа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>α-актин гладких миоцитов</kwd><kwd>chronic gastritis</kwd><kwd>atrophy of the gastric mucosa</kwd><kwd>Marfan syndrome</kwd><kwd>marfan-like state</kwd><kwd>myofibroblasts</kwd><kwd>transforming growth factor β (TGFβ)</kwd><kwd>α-smooth muscle actin</kwd><kwd>collagen type III</kwd><kwd>hereditary disorders of connective tissue</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">Рудой А.
