системной терапии мезенхимальными стволовыми клетками (МСК) на иммунофенотипический профиль (ИФТ) мононуклеарных клеток периферической крови (МПК) у пациентов после трансплантации печени. В исследовании 30 пациентов получали терапию МСК, 30 находились на стандартной иммуносупрессивной терапии. Показано, что в первой группе наблюдалось более быстрое функциональное восстановление трансплантата с ускоренным снижением уровня АЛТ на 7-е и 10-е сутки при статистически значимой более низкой концентрации такролимуса во все сроки наблюдения. Частота иммуноопосредованной дисфункции трансплантата в обеих группах составила 20%, однако в группе МСК отмечен более низкий индекс активности отторжения и отсутствие случаев гуморального отторжения. ИФТ выявило снижение абсолютного количества CD16+56+ естественных киллеров, CD3+CD4+ и CD3+CD8+ эффекторных Т-клеток памяти, наивных зрелых В-лимфоцитов и В-клеток маргинальной зоны при повышении уровня миелоидных и плазмоцитоидных дендритных клеток и иммуносупрессивных В1а-лимфоцитов в группе МСК.</p></abstract><trans-abstract xml:lang="en"><p>Evaluate the effect of combined local and systemic therapy with mesenchymal stem cells (MSCs) on the immunophenotypic profile (IPT) of peripheral blood mononuclear cells (PBMCs) in patients after liver transplantation. Materials and methods: In a randomized prospective study, 30 patients received MSC therapy, while 30 patients were on standard immunosuppressive therapy. IPT of PBMCs was performed using multicolor flow cytometry. Functional parameters of the graft, tacrolimus concentration, morphological signs of rejection, and clinical outcomes were evaluated.</p><p>The MSC group showed faster functional recovery of the graft with accelerated decrease in ALT levels on days 7 and 10 (p&lt; 0.05) with significantly lower tacrolimus concentration throughout the observation period. The frequency of immune-mediated graft dysfunction in both groups was 20%; however, the MSC group showed a lower rejection activity index (RAI 6 (4; 7) versus 7 (4; 8) points) and no cases of humoral rejection. IPT revealed a decrease in the absolute number of CD16+56+ natural killer cells, CD3+CD4+ and CD3+CD8+ effector memory T cells, naive mature B lymphocytes, and marginal zone B cells, with increased levels of myeloid and plasmacytoid dendritic cells and immunosuppressive B1a lymphocytes in the MSC group.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>трансплантация печени</kwd><kwd>мезенхимальные стволовые клетки</kwd><kwd>иммуносупрессия</kwd><kwd>иммунофенотипирование</kwd><kwd>отторжение трансплантата</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liver transplantation</kwd><kwd>mesenchymal stem cells</kwd><kwd>immunosuppression</kwd><kwd>immunophenotyping</kwd><kwd>graft rejection</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">EASL Clinical Practice Guidelines on liver transplantation / D.
