Goal. To assess the expression of neuropeptides and neurotrophins in the skin of patients with atopic dermatitis. Materials and methods. Expression of neuropeptides of substance P and SP-R receptor, calcitonin gene-related peptide (CGRP) and CGRP-R receptor, neurotrophin (nerve growth factor) and TrkA receptor as well as amphiregulin enhancing the growth of nerve fibers and semaphorin-3A terminating the growth of nerve fibers was determined in the skin of patients with atopic dermatitis based on the immunohistochemistry analysis method. Expression of protein PGP9.5 being a marker of nerve fibers was also determined. Results. The authors discovered penetration of nerve fibers expressing substance P and CGRP into the epidermis in patients with atopic dermatitis. Expression of the nerve growth factor and amphiregulin was discovered in epidermis but no expression of semaphorin-3A was discovered. Conclusion. Nerve fibers expressing neuropeptides such as substance P and CGRP can penetrate into the epidermis in patients with atopic dermatitis, which can maintain the inflammatory reaction and itching in such patients. Expression of the growth factors (nerve growth factor and amphiregulin) can contribute to the growth of nerve fibers and their penetration into epidermis against the background of the absence of any expression of semaphorin-3A inhibiting their growth.</p></abstract><trans-abstract xml:lang="ru"><p>На формирование воспалительной реакции в коже, развитие зуда и на состояние нервных волокон могут влиять нейромедиаторы: нейропептиды и нейротрофины. Цель. Оценить экспрессию нейропептидов и нейротрофинов в коже больных атопическим дерматитом. Материал и методы. В коже больных атопическим дерматитом методом иммуногистохимического анализа определяли экспрессию нейропептидов субстанции Р и рецептора SP-R, пептида, связанного с геном кальцитонина (CGRP) и рецептора CGRP-R, нейротрофина - фактора роста нервов и рецептора TrkA, а также амфирегулина, способствующего росту нервных волокон, и семафорина-3А, прекращающего рост нервных волокон. Определяли также экспрессию белка PGP9.5, являющегося маркером нервных волокон. Результаты. Обнаружено прорастание в эпидермис больных атопическим дерматитом нервных волокон, экспрессирующих субстанцию Р и CGRP. В эпидермисе выявлена экспрессия фактора роста нервов и амфирегулина, однако экспрессия семафорина-3А не была обнаружена. Заключение. У больных атопическим дерматитом в эпидермис проникают нервные волокна, экспрессирующие нейропептиды субстанцию Р и CGRP, что может поддерживать у пациентов воспалительную реакцию и зуд. Способствовать росту нервных волокон и проникновению их в эпидермис может экспрессия факторов роста (фактора роста нервов и амфирегулина) на фоне отсутствия экспрессии семафорина-3А, подавляющего их рост.</p></trans-abstract><kwd-group xml:lang="en"><kwd>atopic dermatitis</kwd><kwd>immunohistochemistry analysis</kwd><kwd>epidermis</kwd><kwd>neuropeptides</kwd><kwd>neurotrophins</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>атопический дерматит</kwd><kwd>иммуногистохимический анализ</kwd><kwd>эпидермис</kwd><kwd>нейропептиды</kwd><kwd>нейротрофины</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Elias P.M., Steinhoff M. “Outside-to-inside” (and now back to “outside”) pathogenic mechanisms in atopic dermatitis.
