基质金属蛋白酶(MMPs),包括胶原酶、明胶酶、基质蛋白酶、基质蛋白酶和膜型MMPs在内的一个蛋白酶家族,影响细胞外基质(ECM)的分解和周转。此外,它们是肾小球内ECM降解和转换的主要生理决定因素。肾脏肥大和异常ECM沉积是糖尿病肾病(DN)的标志,提示MMP表达或激活的改变有助于DN的肾脏损伤。在此,我们回顾和总结了支持MMPs在DN发病机制中的作用的最新信息。具体来说,在各种糖尿病实验模型中描述MMPs和/或其组织抑制剂活性失调的研究,包括1型或2型糖尿病的动物模型,人类1型或2型糖尿病的临床研究,以及肾细胞培养研究。
Matrix metalloproteinases (MMPs), a family of proteinases including collagenases, gelatinases, stromely-sins, matrilysins, and membrane-type MMPs, affect the breakdown and turnover of extracellular matrix (ECM).Moreover, they are major physiologic determinants of ECM degradation and turnover in the glomerulus. Renal hypertrophy and abnormal ECM deposition are hallmarks of diabetic nephropathy (DN), suggesting that altered MMP expression or activation contributes to renal injury in DN. Herein, we review and summarize recent information supporting a role for MMPs in the pathogenesis of DN. Specifically, studies describing dysregulated activity of MMPs and/or their tissue inhibitors in various experimental models of diabetes, including animal models of type 1 or type 2 diabetes, clinical investigations of human type 1 or type 2 diabetes, and kidney cell culture studies are reviewed.
