摘要
动脉粥样硬化是急性心血管疾病的主要病理生理过程。危险的生命状况,如心肌梗死和缺血性中风,是由脆弱的动脉粥样硬化斑块的突然破裂,其特点是薄、高度发炎和胶原纤维。而先天和适应性炎症逐渐成为这个过程的驱动力,更是对中性粒细胞(PMN)的参与。在过去的二十年里,中性粒细胞在不同的酶的释放促进斑块易损性中起到重要的作用,实验技术的进步,如明胶酶(基质金属蛋白酶)和胶原酶,弹性蛋白酶髓过氧化物酶的使用。因此,中性粒细胞及其产物的循环水平的研究已在一级和二级预防斑块的不稳定性对心血管疾病的潜在标志物。此外,不同类别的针对中性粒细胞活化药物的开发正在成为一个有趣的研究领域。本综述将提供对中性粒细胞在促进斑块的易损性也讨论治疗策略针对中性粒细胞在斑块易损性的潜在影响的更新。

摘要: Atherosclerosis is the main pathophysiological process underlying acute cardiovascular diseases. Life-threatening conditions, such as myocardial infarction and ischemic stroke, are provoked by the sudden rupture of vulnerable atherosclerotic plaques, characterized by thin, highly inflamed and collagen-poor fibrous cap. Whereas both innate and adaptive inflammation progressively emerged as driving force of this processes, less is known about the involvement of neutrophils (PMNs). Advances in laboratory techniques during the last two decades disclosed that PMNs play a crucial role in promoting plaque vulnerability by the release of different enzymes, such as gelatinases (matrix metalloproteinases) collagenases, elastase and myeloperoxidase. Accordingly, circulating levels of PMNs and their products have been investigated as potential markers of plaque instability in both primary and secondary prevention on cardiovascular diseases. In addition, the development of different classes of drugs targeting PMNs activation is emerging as an interesting field of research. This narrative review will provide an update on the role of PMNs in promoting plaque vulnerability also discussing the potential effects of therapeutic strategies targeting PMN on plaque vulnerability.
