Hypertension is one of the leading risk factors for the development of heart failure. Despite being a multifactorial disease, in recent years, preclinical and clinical studies suggest strong evidence of the pivotal role of inflammatory cells and cytokines in the remodeling process and cardiac dysfunction. During the heart remodeling, activation of extracellular matrix metalloproteinases (MMPs) occurs, with MMP-2 being one of the main proteases secreted by cardiomyocytes, fibroblasts, endothelial and inflammatory cells in cardiac tissue. In this review, we will address the process of cardiac remodeling and injury induced by the increase in MMP-2 and the main signaling pathways involving cytokines and inflammatory cells in the process of transcriptional, secretion and activation of MMP-2. In addition, an interaction and coordinated action between MMP-2 and inflammation are explored and significant in maintaining the cardiac cycle. These observations suggest that new therapeutic opportunities targeting MMP-2 could be used to reduce inflammatory biomarkers and reduce cardiac damage in hypertension.
高血压是心力衰竭发生的主要危险因素之一。尽管心力衰竭是一种多因素疾病,但近年来,临床前和临床研究有力地证明了炎症细胞和细胞因子在重塑过程及心脏功能障碍中起关键作用。在心脏重塑过程中,细胞外基质金属蛋白酶(MMPs)被激活,其中MMP-2是心脏组织中心肌细胞、成纤维细胞、内皮细胞和炎症细胞分泌的主要蛋白酶之一。在本综述中,我们将阐述MMP-2增加所诱导的心脏重塑和损伤过程,以及在MMP-2转录、分泌和激活过程中涉及细胞因子和炎症细胞的主要信号通路。此外,还探讨了MMP-2与炎症之间的相互作用和协同作用,它们在维持心动周期方面具有重要意义。这些观察结果表明,针对MMP-2的新治疗机会可用于降低炎症生物标志物并减少高血压患者的心脏损伤。
