Иммунная система организма, включающая врожденный и адаптивный иммунный ответы, является драйвером патогенеза атеросклероза и играет не сколько протективную, антиатерогенную, сколько проатерогенную роль. На сегодняшний день пристальное внимание уделяется изучению Т-лимфоцитов, которые обладают как про-, так и антиатерогенными свойствами. В настоящем исследовании проведена оценка характера Т-клеточных субпопуляций в зависимости от макрофагального компонента в атеросклеротической бляшке. С этой целью были проанализированы транскриптомные данные единичных клеток атеросклеротических бляшек человека из базы данных SRА (SRP199578, SRP274629, SRP287809). Выявлена прямо-пропорциональная зависимость CD8+ стволовых Т-клеток памяти (TSCM) и отношения пула CD8+ Т-клеток к пулу макрофагов. Кроме того, показаны различия в лиганд-рецепторных взаимодействиях среди TSCM при разном соотношении CD8+ Т-клеток и макрофагов, в частности IL2RA, SELP, LEPR, SDC2, CCR6, TGFBR3, IL1R2, CD247, CXCR6, LIFR, ERBB3.</p></abstract><trans-abstract xml:lang="en"><p>Atherosclerosis is a multicomponent disease that depends on immune response, and physiological condition of the arteries. Innate and adaptive immunity act as a driver of the pathogenesis of atherosclerosis rather than play an atheroprotective role. T-lymphocytes, as a key part of the immune response, can exhibit both pro- and anti-atherogenic properties. In this regard, the study of this cell population is of particular interest. In the present study, we performed the analysis of T-cells subpopulations depending on the T-cells to macrophages ratio. We applied bioinformatics methods to three single-cell RNA-sequencing datasets of human coronary and carotid arteries downloaded from the SRA database (SRP199578, SRP274629, SRP287809). The present study demonstrated a direct proportionality between CD8+ T memory stem cells (TSCM) and the ratio of the CD8+ T cells pool to the macrophage pool. In addition, we revealed differences in TSCM receptors (IL2RA, SELP, LEPR, SDC2, CCR6, TGFBR3, IL1R2, CD247, CXCR6, LIFR, ERBB3) that are involved in ligand-receptor interactions with other atherosclerotic plaques cell populations, between two groups of patients with high and low CD8+ T-cells to macrophages ratio.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>атеросклероз</kwd><kwd>Т-лимфоциты</kwd><kwd>макрофаги</kwd><kwd>scRNA-seq</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atherosclerosis</kwd><kwd>T cells</kwd><kwd>macrophages</kwd><kwd>scRNA-seq</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">Benjamin E.J., Muntner P., Alonso A. et al.
