动脉粥样硬化是一种慢性炎症性疾病,在大多数国家是发病和死亡的主要原因。炎症是导致斑块不稳定和随后急性冠状动脉综合征(ACS)发作的原因,ACS是住院治疗的主要原因之一。因此,探索ACS的潜在发病机制是一个值得关注的问题,寻找替代的治疗靶点是非常紧迫的。白细胞介素-37(IL-37)抑制促炎趋化因子和细胞因子的产生,并作为先天性和适应性免疫的天然抑制剂。有趣的是,我们以前的研究与小鼠模型表明,IL-37减轻心脏重塑和心肌缺血/再灌注损伤。值得注意的是,我们的临床研究表明,IL-37升高,并在ACS患者中发挥有益作用。此外,树突状细胞(DC)协调免疫和耐受,并且致耐受性DC(tDC)的特征在于更多的免疫抑制细胞因子分泌。如所预期的,IL-37处理的DC是致耐受性的。因此,我们推测IL-37或IL-37处理的DC是一种新的治疗ACS的可能性,IL-37的确切机制需要进一步研究。
As a chronic inflammatory disease, atherosclerosis is a leading cause of morbidity and mortality in most countries. Inflammation is responsible for plaque instability and the subsequent onset of acute coronary syndrome (ACS), which is one of the leading causes of hospitalization. Therefore, exploring the potential mechanism underlying ACS is of considerable concern, and searching for alternative therapeutic targets is very urgent. Interleukin-37 (IL-37) inhibits the production of proinflammatory chemokines and cytokines and acts as a natural inhibitor of innate and adaptive immunity. Interestingly, our previous study with murine models showed that IL-37 alleviated cardiac remodeling and myocardial ischemia/reperfusion injury. Of note, our clinical study revealed that IL-37 is elevated and plays a beneficial role in patients with ACS. Moreover, dendritic cells (DCs) orchestrate both immunity and tolerance, and tolerogenic DCs (tDCs) are characterized by more secretion of immunosuppressive cytokines. As expected, IL-37-treated DCs are tolerogenic. Hence, we speculate that IL-37- or IL-37-treated DCs is a novel therapeutic possibility for ACS, and the precise mechanism of IL-37 requires further study.
