Central to the pathologic changes in developing aortic aneurysms are alterations in the abundance and activity of proteases, of which the most important for aneurysm production comprise the matrix metalloproteinase (MMP) family. In this review, literature demonstrating the role of MMPs in the development of aortic aneurysms is presented, with emphasis on the parity and disparity between the thoracic and abdominal aorta. Furthermore, the role of embryologic cellular origins and evidence of phenotypic switch will be addressed in terms of how this process alters MMP production during aneurysm development.
发育性主动脉瘤病理变化的核心是蛋白酶的丰度和活性改变,其中对动脉瘤形成最重要的是基质金属蛋白酶(MMP)家族。在本综述中,将展示证明MMPs在主动脉瘤发展中作用的文献,重点关注胸主动脉和腹主动脉之间的异同。此外,将从胚胎细胞起源过程如何在动脉瘤发展过程中改变MMP产生的角度,探讨胚胎细胞起源的作用和表型转换的证据。
