Circulating CD8+ T cells and monocytes are activated during human immunodeficiency virus (HIV) infection and colocalize in the aortas of simian immunodeficiency virus-infected nonhuman primates. We hypothesized that CD8+ T cells could exert a proatherosclerotic effect via paracrine actions on monocytes. We found that T-cell receptor-stimulated CD8+ T cells induce monocytes to express tissue factor, a potent activator of coagulation. Tumor necrosis factor was both necessary and sufficient for this effect.
循环 CD8+T 细胞和单核细胞在人类免疫缺陷病毒 (HIV) 感染期间被激活,并在感染猴免疫缺陷病毒的非人类灵长类动物的主动脉中聚集。我们假设 CD8+T 细胞可以通过旁分泌作用对单核细胞发挥促动脉粥样硬化作用。我们发现,T 细胞受体刺激的 CD8+T 细胞诱导单核细胞表达组织因子,组织因子是凝血的有效激活剂。肿瘤坏死因子是这种作用所必需的,也是充分的。
