To analyze the content of peripheral blood lymphocyte subpopulations with cytotoxic, killer, and regulatory functions in female patients with recurrent implantation failures in assisted reproductive technology programs. Subjects and methods. The investigation enrolled 48 patients with recurrent implantation failures in an IVF program and 26 fertile women with their last child aged less than 2 years. Results. There was a reduction in T lymphocytes (CD3+) and T lymphocytes with cytotoxic function (CD3+CD8+) and an increase in innate immunity cells with both cytotoxic (CD3-CD8+) and killer (CD56+, CD16+, CD56,16+) functions. The group patients showed a significant rise in gd+Т cell levels in a cryo-cycle (p = 0.005). Conclusion. In patients with recurrent implantation failures, the composition of lymphocyte subpopulations is characterized by a decrease in T lymphocytes (CD3+) and Tlymphocytes with cytotoxic function (CD3+CD8+) and by an increase in innate immunity cells with both cytotoxic and killer functions.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования. Анализ содержания в периферической крови субпопуляций лимфоцитов с цитотоксической, киллерной и регуляторной функцией у пациенток с повторными неудачами имплантации в программах вспомогательных репродуктивных технологий (ВРТ). Материал и методы. В исследование были включены 48 пациенток с повторными неудачами имплантации в программе ЭКО и 26 фертильных женщин, имеющих последнего ребенка не старше 2 лет. Результаты исследования. Выявлено снижение содержания лимфоцитов (CD3+-клеток) и Т-лимфоцитов с цитотоксической функцией (CD3+CD8+), увеличение содержания клеток врожденного иммунитета как с цитотоксической (CD3-CD8+), так и с киллерной функцией (CD56+, CD16+, CD56,16+). У группы пациенток в криоцикле отмечено достоверное увеличение содержания gd+Т-кле-ток (р=0,005). Заключение. У пациенток с повторными неудачами имплантации субпопуляционный состав лимфоцитов характеризуется снижением содержания Т-лимфоцитов (CD3+-клеток) и Т-лимфоцитов с цитотоксической функцией (CD3+CD8+), увеличением содержания клеток врожденного иммунитета как с цитотоксической, так и с киллерной функцией.</p></trans-abstract><kwd-group xml:lang="en"><kwd>CD56</kwd><kwd>CD16</kwd><kwd>CD3CD8</kwd><kwd>CD3CD8</kwd><kwd>recurrent implantation failures</kwd><kwd>CD56</kwd><kwd>CD16</kwd><kwd>CD3-CD8</kwd><kwd>CD3CD8</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>повторные неудачи имплантации</kwd><kwd>gdТ-клетки</kwd><kwd>gdТ cells</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Coughlan C., Ledger W., Wang Q., Liu F., Demirol A., Gurgan T. et al.
