A number of studies demonstrated a positive effect of system agonists of kappa-opioid receptors in the treatment of uremic pruritus, nodular pruritus, paraneoplastic and cholestatic pruritus. This research demonstrates an expression of kappa-opioid receptors in human skin (basal keratinocytes, dendritic cells, epidermal melanocytes and fibroblasts of the upper dermis) detected with the use of different immunochemistry methods.</p></abstract><trans-abstract xml:lang="ru"><p>В качестве одной из причин хронического зуда в настоящее время предполагается дисбаланс системы мю- и каппа-опиоидных рецепторов в коже или в центральной нервной системе. В нескольких исследованиях продемонстрирован положительный эффект системных агонистов каппа-опиоидных рецепторов в лечении уремического зуда, узловатой почесухи, паранеопластического и холестатического зуда. В настоящей работе демонстрируется экспрессия каппа-опиоидных рецепторов в коже человека (базальных кератиноцитах, дендритных клетках, меланоцитах эпидермиса и фибробластах сосочкового слоя дермы), определенная с помощью различных иммуногистохимических методик.</p></trans-abstract><kwd-group xml:lang="en"><kwd>expression of kappa-opioid receptors</kwd><kwd>pruritus</kwd><kwd>agonists of kappa-opioid receptors</kwd><kwd>immunochemistry studies</kwd><kwd>dynorphin</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>экспрессия каппа-опиоидных рецепторов</kwd><kwd>зуд</kwd><kwd>агонисты каппа-опиоидных рецепторов</kwd><kwd>иммуногистохимические исследования</kwd><kwd>динорфин</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Satoh M., Minami M.
