树突状细胞在动脉粥样硬化中的作用

The role of dendritic cells in atherosclerosis

基础和临床研究均证实，炎症反应在动脉粥样硬化（atherosclerosis，As）的发生、发展及其导致的临床事件过程中起着重要作用。在发生As的血管内膜和粥样斑块中可见T淋巴细胞、巨噬细胞以及树突状细胞（dendmiccell，Dc）聚集现象。作为激活T淋巴细胞最主要的抗原提呈细胞，Dc具有决定T淋巴细胞活化、凋亡以及聚集等的重要功能。文章就Dc与As病变的相关性进行了综述。

Both basic and clinical studies have confwrned that inflammatory response plays an important role in the occurrence and development of atherosclerosis （AS） as well as its caused clinical events. The aggregation phenomena of T lymphocytes, macrophages and dendritic cells （DCs） can be observed in intima and atherosclerotic plaques in the event of atherosclerosis. As the most important antigen-presenting cells activating T lymphocytes, DCs have the important functions of determining T lymphocyte activation, apoptosis, and aggregation. This article reviews the con＇elation between DCs and atherosclerotic lesions.
