Higher levels of Tregs have been reported in the peripheral blood of patients with several types of tumors. The aum of this work was the investigation of the number of CD4+CD25+ cells in peripheral blood of patients with prostate cancer (PC), prostate adenoma (PA) and urolithiasis as control group. Levels of Tregs in the peripheral blood of patients were measured by flow cytometry. Data were analyzed using unpaired Students t test. The levels of Tregs in the peripheral blood of patients with PC and PA were significantly higher than those in control group. These findings show the potential importance of Tregs in modifying immune responses not only in patients with PC but in patients with PA too. Although longer studies are necessary to confirm these findings, these studies also show for the first time the differences in Treg level in peripheral blood of patients with PA, and thus, provide a basis for immunotherapy trials involving the inhibition of Tregs in prostate adenoma and PCa patients.</abstract><trans-abstract xml:lang="ru">CD4+CD25+ регуляторные Т-лимфоциты (Tрег) ингибируют индукцию и функции антигенспецифических Т-клеток при активации клеточного антигенспецифического иммунного ответа. Повышенный уровень Трег обнаружен у больных при различных типах опухолей. Целью работы явилось изучение содержания CD4+CD25+ клеток в периферической крови у больных раком и у больных аденомой предстательной железы (РПЖ и АПЖ) в сравнении с больными мочекаменной болезнью, у которых опухолей не было (группа контроля). Уровень Трег в периферической крови определяли с помощью проточной цитофлуориметрии, статистический анализ проводили с использованием метода Стьюдента. У больных АПЖ и РПЖ обнаружено достоверное повышение уровня Трег. Полученные результаты свидетельствуют о возможной роли Трег в подавлении иммунного ответа не только у больных РПЖ, но и при АПЖ. Полученные результаты свидетельствуют о целесообразности проведения исследований, направленных на ингибирование Трег у больных АПЖ и РПЖ.</trans-abstract><kwd-group xml:lang="en"><kwd>regulatory T lymphocytes</kwd><kwd>peripheral blood</kwd><kwd>prostate cancer</kwd><kwd>prostate adenoma</kwd><kwd>urolithiasis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>регуляторные Т-лимфоциты</kwd><kwd>периферическая кровь</kwd><kwd>рак предстательной железы</kwd><kwd>аденома предстательной железы</kwd><kwd>мочекаменная болезнь</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Adler A.J.
