One of the components of mast cell granules is chymase. For its specific detection, various reagents for immunohistochemistry, which have different specifity, are used. This circumstance does not allow us to accurately assess the subpopulations of myocardial mast cells. The purpose of this study was to evaluate the suitability of various reagents to selective detection of myocardial mast cells and to test the hypothesis of the existence of a population of mast cells staining with alcian blue and having chymase negative reaction. Analysis of the results of the various protocols presented in this work showed that, in comparison with goat polyclonal antibodies to chymase, mouse monoclonal antibodies have greater specificity, and preliminary staining of sections with alcian blue makes it possible to neutralize the nonspecific detection of cardiomyocyte lipofuscin. In addition, all the proposed protocols make it possible to detect the morphological heterogeneity of mast cells and their granules in the human myocardium.</p></abstract><trans-abstract xml:lang="ru"><p>В последние десятилетия уделяется особое внимание роли тучных клеток в патогенезе сердечно-сосудистых заболеваний, в том числе внезапной сердечной смерти. Одним из компонентов гранул тучных клеток является химаза. Для ее иммуногистохимического выявления используют реагенты, обладающие различной специфичностью. Данное обстоятельство не позволяет точно оценить субпопуляции тучных клеток миокарда. Цель данного исследования состояла в оценке пригодности различных реагентов для селективного выявления тучных клеток миокарда и проверке гипотезы о существовании популяции тучных клеток, способных к окраске альциановым синим при негативной реакции на химазу. Анализ результатов использования различных протоколов для выявления тучных клеток показал, что, в сравнении с козьими поликлональными антителами к химазе, мышиные моноклональные антитела обладают большей специфичностью, а предварительное окрашивание срезов альциановым синим позволяет нивелировать неспецифическое мечение антителами липофусцина кардиомиоцитов. Кроме этого, все предложенные протоколы позволяют обнаружить морфологическую гетерогенность тучных клеток и их гранул в миокарде человека.</p></trans-abstract><kwd-group xml:lang="en"><kwd>mast cells</kwd><kwd>chymase</kwd><kwd>human myocardium</kwd><kwd>immunohistochemistry</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тучные клетки</kwd><kwd>химаза</kwd><kwd>миокард человека</kwd><kwd>иммуногистохимия</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Правительство Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Government of the Russian Federation</institution></institution-wrap></funding-source><award-id>FGWG-2024-0015</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Атякшин Д.А., Бухвалов И.Б., Тиманн М. 2018.
