Данные популяции отличаются высокой гетерогенностью и разделяются на несколько субпопуляций, отличающихся по  степени экспрессии маркеров CD56  и CD16  и функциональной активностью.  Исследование гетерогенности данных популяций лимфоцитов у здоровых доноров актуально, так как является основой для изучения нарушений баланса между различными субпопуляциями у онкологических больных. Изменения  соотношения выше  представленных субпопуляций  могут обладать прогностическим и клиническим значением при опухолевых заболеваниях. Было  проведено исследование лимфоцитов периферической крови 50 здоровых доноров. При  анализе популяции NK-лимфоцитов было  выявлено 18,0±11,3% антиген-положительных клеток, колебания значений составило от 7,6 до 29,2%, в то время как количество клеток с фенотипами CD3-CD56+  и CD3-CD16+ было равно  16,2±8,1 и 11,0±6,7% соответственно. Анализ субпопуляционной структуры показал, что основной пул NK-клеток представлен CD56dimCD16dim   клетками 52,3±19,9%, а минорные субпопуляции CD56dimCD16bright, CD56-CD16+, CD56brightCD16 составляют 0,3±0,2, 1,7±0,9 и 1,3±0,6% соответственно. При  исследовании внутриклеточного содержания перфорина оказалось, что количество CD56+Perf+  клеток в среднем равно  25,1±14,8%, а CD16+Perf+ – 23,8±16,0%. Цитометрический анализ  показал, что перфорин преимущественно содержится в CD56dimCD16dim NK-лимфоцитах, в то время как  CD56dimCD16bright, CD56-CD16+, CD56brightCD16- перфорина не содержали. В работе  впервые  обнаружена субпопуляция NK-клеток  с  иммунофенотипом СD56dimCD16dim,  не  содержащая внутриклеточный перфорин (2,0%). Популяция NKT-клеток с фенотипом СD3+CD16/СD56+   выявляется в 7,1% (25% – 3,45; 75% – 8,75) антиген-положительных клеток в диапазоне от 2,5 до 11,9% и не подчиняется законам нормального распределения. При  анализе с помощью комбинации МКА CD3/CD56/CD16 количество CD3+CD56+  клеток составило 4,33%  (25% – 2,25; 75% – 7,3),  а количество  CD3+CD16+ – 3,087%  (25% – 0,9; 75% – 6,2).  Оказалось, что различия между  определением с помощью тест-системы CD3/CD16/CD56 и с помощью CD3/CD16 является статистически значимой  (p &lt; 0,05).  Было  показано, что основной пул NKT-клеток составляют CD56+CD16- клетки, количество которых 5,45% (25% – 2,95; 75% – 7,3) среди CD3+  лимфоцитов. При  этом были выявлены две минорные субпопуляции, отличающиеся по экспрессии антигенов CD56  и CD16. Так  уровень CD56-CD16+   составил 3% (25%  – 0,25;  75% – 3,05),  а количество CD56+CD16+   оказалось равным 0,67% (25% – 0,25; 75% – 0,9). Таким образом, широкое фенотипическое разнообразие NK- и NKT- клеток отражает их способность к реализации различной функциональной активности. Данное исследование, указывающее на высокую гетерогенность NK- и NKT-лимфоцитов, может  послужить основой для изучения нарушений баланса между различными субпопуляциями этих клеток у онкологических больных.</p></abstract><trans-abstract xml:lang="en"><p>Natural killer(NK) and  NKT lymphocytes are important components of innate immunity, and compose a first-line defense against cancer. These populations are characterized by high heterogeneity and are divided into several subpopulations, by differences in functional activity as well as CD56  and CD16  expression. Studying  heterogeneity for these  lymphocyte populations in healthy  donors  is important, due  to imbalance between  different  lymphocyte subsets in cancer patients. Changes in the ratio of these subpopulations may be of prognostic and clinical  significance in malignant diseases. The present  study was conducted with peripheral blood  lymphocytes in 50 healthy  donors. When  analysing  population of NK  lymphocytes we have identified 18.0±11.3% of antigen-positive cells, their fluctuations ranged  from 7.6 to 29.2%, whereas average number of cells with  CD3-CD56+ and  CD3-CD16+   phenotypes was equal  to 16,2±8.1%, and  11,0±6.7%, respectively. The  subpopulation analysis  showed  that  the  primary  pool  of NK  cells  was presented by CD56dimCD16dim cells  by  52.3±19.9 percent.  We  detected  minor   subpopulations,  e.g.,  CD56dimCD16bright,  CD56-CD16+, CD56brightCD16- (0.3±0.2%, 1.7±0.9%, and  1.3±0.6%,  respectively). Search  for  intracellular perforin has revealed  that the number of CD56+Perf+ cells comprized 25.1±14.8%, CD16+Perf+, 23.8±16.0%. Cytometric analysis showed that perforin is found, predominantly, in CD56dimCD16dim NK lymphocytes, whereas the cells with CD56dimCD16bright, CD56-CD16+, CD56brightCD16- immunophenotypes did not produce perforin. For the first time, we have discovered a subpopulation of NK cells with the СD56dimCD16dim immunophenotype that did not contain intracellular perforin (2.0%).  The NKT cell population with СD3+CD16/СD56+  phenotype was detected in 7.1% (25% – 3.45; 75% – 8.75) antigen-positive cells, within a range of 2.5 to 11.9%. Analysis with a combination of monoclonal antibodies CD3/CD56/CD16 has shown that the number of CD3+ CD56+ cells was 4.33% (25% – 2.25; 75% – 7.3), whereas the number of CD3+CD16+ was 3.087% (25% – 0.9; 75% – 6.2). These  data  demonstrate that  the differences in results  between  the CD3/CD16/CD56, and  CD3/CD16 test systems are statistically significant  (p &lt; 0.05). It was shown that the primary-pool NKT-cells are CD56+CD16- cells, whose number is about 5.45% (25% – 2.95; 75% – 7.3) among  total CD3+ lymphocyte population. Two minor subpopulations were also detected which differed in expression  of CD56 and CD16 antigens. Hence, the level of CD56-CD16+ cells was 3% (25% – 0.25; 75% – 3.05),  and the number of CD56+CD16+ was equal to 0.67% (25% – 0.25; 75% – 0.9). Hence, the observed wide phenotypic diversity of NK and NKT-cells reflects their  ability  to exert  various  functional activities.  This  study, showing  high  heterogeneity of NK  and  NKT lymphocytes, may serve as a basis for the study of imbalances between  different  subpopulations of these cells in cancer patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>проточная цитометрия</kwd><kwd>иммунофенотип</kwd><kwd>NK-лимфоциты</kwd><kwd>NKT-лимфоциты</kwd><kwd>перфорин</kwd><kwd>субпопуляции лимфоцитов</kwd><kwd>CD56</kwd><kwd>CD16</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flow cytometry</kwd><kwd>immunophenotype</kwd><kwd>NK cells</kwd><kwd>NKT cells</kwd><kwd>perforin</kwd><kwd>lymphocyte subsets</kwd><kwd>CD56</kwd><kwd>CD16</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">Балмасова И.П., Ющук Н.Д., Знойко О.О., Шмелева Е.В., Дунда Н.И., Еремина О.Ф., Максимов С.Л., Зайцева М.Н., Малова Е.С., Сепиашвили Я.Р.
