胸主动脉夹层是影响主动脉的主要疾病之一,具有很高的死亡率。提高我们对这种疾病的病理生物学的了解可能有助于我们开发预防夹层和随后的动脉瘤形成和破裂的医学治疗方法。夹层与主动脉中膜退行性变有关。最近的研究表明,在夹层的主动脉组织中,一类蛋白水解酶--基质金属蛋白酶(MMPs)的表达和激活增加,这表明MMPs可能在本病中发挥了重要作用。抑制MMPs可能有助于减少与夹层相关的基质金属蛋白酶介导的主动脉损伤。本文回顾了最近的文献,总结了我们对基质金属蛋白酶在胸主动脉夹层的病理生物学中的作用的认识。还讨论了抑制基质金属蛋白酶作为未来主动脉夹层治疗的潜在重要性。
Thoracic aortic dissection, one of the major diseases affecting the aorta, carries a very high mortality rate. Improving our understanding of the pathobiology of this disease may help us develop medical treatments to prevent dissection and subsequent aneurysm formation and rupture. Dissection is associated with degeneration of the aortic media. Recent studies have shown increased expression and activation of a family of proteolytic enzymes—called matrix metalloproteinases (MMPs)—in dissected aortic tissue, suggesting that MMPs may play a major role in this disease. Inhibition of MMPs may be beneficial in reducing MMP-mediated aortic damage associated with dissection. This article reviews the recent literature and summarizes our current understanding of the role of MMPs in the pathobiology of thoracic aortic dissection. The potential importance of MMP inhibition as a future treatment of aortic dissection is also discussed.
