С целью анализа характера экспрессии биомолекулярных маркеров выполнено ИГХ-исследование с использованием первичных моноклональных антител к CD44, MMP9, TGFβ1. Для изучения морфологических особенностей кератопатий на фоне глаукомы были использованы окрашивание гистологических препаратов гематоксилином и эозином; гистохимическое окрашивание (PAS-реакция, MSB, по Массону, конго-красным; ИГХМ с использованием маркеров CD44, MMP9, TGFβ1).</p><p>Согласно полученным результатам, в группе пациентов с ЭЭД на фоне применения инъекционной формы гиалуроновой кислоты снижается активность воспаления за счет снижения эпителиальной и стромальной экспрессии CD44 и ММР9, уменьшается проапоптотическое и профибротическое действие TGFβ1.</p></abstract><trans-abstract xml:lang="en"><p>The purpose was to determine the effectiveness of endothelial-epithelial dystrophy treatment with subconjunctival injection of low molecular weight hyaluronic acid.</p><p>Prospective material of 14 corneas with different epithelialepithelial dystrophy forms were examined and treated.

The proapoptotic and profibrotic action of TGFβ1 decreases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гиалуроновая кислота</kwd><kwd>регенерация</kwd><kwd>дистрофия роговицы</kwd><kwd>иммуногистохимия</kwd><kwd>эндотелиально-эпителиальная дистрофия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hyaluronic acid</kwd><kwd>dry eye disease</kwd><kwd>regeneration</kwd><kwd>corneal dystrophy</kwd><kwd>immunohistochemistry</kwd><kwd>endothelial-epithelial dystrophy</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">McCarey, B.
