Учитывая, что при инсульте Т-лимфоциты с регуляторной активностью участвуют  в различных патофизиологических процессах, включая воспаление, иммунодепрессию, поражение и репарацию мозговой ткани, исследование Т-клеток в качестве потенциальных биомаркеров представляет особое значение.  Целью работы явилось исследование субпопуляций циркулирующих Т-клеток  с  фенотипом Т-хелперов 1 типа  (Тh1), регуляторных Т-клеток (Тreg)  и их соотношения у пациентов в остром периоде  ИИ в зависимости от тяжести, выраженности воспалительного ответа  и 3-месячного исхода (по  модифицированной шкале Рэнкина, mRs).  В исследование был  включен 61 пациент с впервые выявленным ИИ (тяжесть по шкале NIHSS ≥ 5 баллов) в остром периоде (24-48  ч после  инсульта) и 20 сопоставимых по полу  и возрасту доноров. Лабораторное обследование включало оценку лейкоцитоза, нейтрофильно-лимфоцитарного индекса (НЛИ) и СРБ. Исследование Т-клеток проводили в популяции мононуклеарных клеток периферической крови. Тh1 и Тreg оценивали, соответственно, по содержанию CD4+IFNγ+  и CD4+CD25hiТ-клеток методом проточной цитофлюориметрии. В первые  24-48  ч с момента нарушения мозгового кровообращения пациенты характеризовались повышенными показателями лейкоцитоза, НЛИ и СРБ. Тяжесть инсульта ассоциировалась с большей выраженностью системной воспалительной реакции, что подтверждалось достоверно более  высокими показателями лейкоцитоза, НЛИ и СРБ при тяжелом инсульте, чем при инсульте легкой степени тяжести, а также  наличием прямой взаимосвязи NIHSS с уровнем НЛИ и СРБ. Также  у пациентов отмечалось достоверное снижение CD4+IFNγ+Тh1-клеток, возрастание CD4+CD25hiТreg и выраженное снижение индекса Th1/Treg. При этом в группе с NIHSS ≥ 8 (среднетяжелый и тяжелый инсульт) доля CD4+IFNγ+Т-клеток  находилась в прямой, а содержание CD4+CD25hiТ-клеток – в обратной корреляционной зависимости с уровнем СРБ и НЛИ. Изменения Т-клеточных субпопуляций были  более выражены у пациентов с благоприятным 3-месячным исходом (mRs  &gt; 3). В результате пациенты с неблагоприятным исходом (mRs  ≤ 3) отличались от оппозитной группы более  высоким содержанием CD4+IFNγ+, меньшим уровнем CD4+CD25hiТ-клеток и более (4-кратно) высоким индексом соотношения CD4+IFNγ+/CD4+CD25hi. ROC-анализ выявил «хорошее»  качество прогноза, основанного на  оценке индекса CD4+IFNγ+/CD4+CD25hi   в качестве монопредиктора  неблагоприятного исхода (AUC  = 0,75)  и «очень  хорошее» качество прогноза при  комбинации указанного индекса с баллом по  шкале NIHSS (AUC   = 0,82).  Полученные данные позволяют предположить, что  уменьшение Th1/Тreg индекса за счет снижения CD4+IFNγ+  и повышения CD4+CD25hiТ-клеток в остром периоде ИИ является компенсаторной реакцией, направленной на  сдерживание воспалительного ответа,  и характеризуется прогностической значимостью при  использовании в качестве раннего предиктора 3-месячного исхода.</p></abstract><trans-abstract xml:lang="en"><p>Early prediction for ischemic stroke (IS) outcome is a major challenge since it may help to optimize treatment program and  to make  it more  personalized. Since  T cells with  regulatory activity  are involved  in different  pathophysiological processes  in brain  stroke,  including inflammation, immune suppression, brain damage  and  repair, the  study  of T cells as potential biomarkers has essential  importance. The  present  work aimed to study the circulating T cell subsets with phenotype of type 1 T helper cells (Th1) and regulatory T cells (Treg), and their  ratio during  the acute  phase of IS, depending on stroke severity, inflammatory response  and 3-month outcome (according to modified Rankin scale, mRs).  Patients and methods. The study included 61 patients with a newly diagnosed IS (severity according to NIHSS ≥ 5), in the first 24-48 h after stroke onset, and 20 age/sex-related healthy  donors. Laboratory examination included assessment of leukocytosis, neutrophillymphocyte ratio  (NLR) and CRP  concentration. Mononuclear cells were isolated  from peripheral blood  to study T cell subsets. Th1 and Tregs were measured by FACS  analysis as CD4+IFNγ+  and CD4+CD25hiT cells, respectively. During the first 24-48 h after stroke, the patients had elevated values of leukocyte counts, NLR and CRP. Higher  levels of these parameters in severe stroke compared with mild stroke, as well as direct correlation of NIHSS with  NLR  and  CRP  evidenced that  the  stroke  severity  was associated with  more  pronounced inflammatory response. Patients were also characterized by a significant  decrease in CD4+IFNγ+Th1  cells, an  increase  in CD4+CD25hiTreg, and  a marked  decrease in Th1/Treg ratio.  Furthermore, in patients with NIHSS ≥ 8 (moderate and severe stroke), the percentage of CD4+IFNγ+T cells was in direct  correlation, and the number of CD4+CD25hiT cells was inversely related to CRP  and NLR  values. The changes of T cell subsets were more  pronounced in patients with  a favorable  3-month outcome (mRs  &gt; 3). As a result,  the  patients with poor outcome (mRs  ≤ 3) had higher  CD4+IFNγ+T cell proportion, lower CD4+CD25hiT cell percentage and  4-fold  higher  CD4+IFNγ+/CD4+CD25hi  ratio  compared with opposing  group.  ROC  analysis  revealed  a “good” quality of prognosis  based on evaluation of the CD4+IFNγ+/CD4+CD25hi  ratio as a monopredictor of adverse outcome (AUC  = 0.75) and “very good”  quality  of prognosis  when the indicated ratio was combined with  NIHSS scale  (AUC  = 0.82).  The  data  obtained suggest  that  a decrease of Th1/Тreg ratio,  due  to  a decrease in CD4+IFNγ+  and increased CD4+CD25hiT cell counts  during the acute  phase of ischemic stroke is a compensatory reaction directed at inhibition of inflammatory response, and has a prognostic significance as early predictor of the outcome at 3 months.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>CD4+IFN-γ+</kwd><kwd>CD4+CD25hi</kwd><kwd>ишемический инсульт</kwd><kwd>исходы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CD4+IFNγ+</kwd><kwd>CD4+CD25hi</kwd><kwd>ischemic stroke</kwd><kwd>outcomes</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">Bonaventura A., Liberale L., Vecchié A., Casula M, Carbone F., Dallegri F., Montecucco F.
