细胞外基质(ECM)重构是对各种心脏损伤的反应,包括梗死、压力过载和扩张性肌病。每种类型的重塑都需要不同类型的ECM转换和沉积,但心肌纤维胶原含量的增加被认为是每种病理中心功能障碍的一个贡献特征。此外,衰老,也与心脏胶原蛋白含量的增加有关。表征ECM组成和心肌成纤维细胞在纤维化胶原积累组装过程中的差异的重要性,对于设计减少并最终逆转心脏纤维化的策略至关重要。胶原交联是影响胶原沉积和不溶性的一个因素,直接影响组织特性,如硬度。在这篇综述中,将讨论三种不同类型的胶原交联在心脏纤维化中发挥重要作用;那些由赖氨酸氧化酶催化的,那些由谷氨酰胺转胺酶催化的,以及那些由添加晚期糖基化终产物的非酶修饰引起的。深入了解控制心肌胶原交联的细胞机制将为探索治疗与心脏纤维化相关疾病的新疗法提供新的途径。
Extracellular matrix (ECM) remodeling occurs in response to various cardiac insults including infarction, pressure overload and dilated myopathies. Each type of remodeling necessitates distinct types of ECM turnover and deposition yet an increase in myocardial fibrillar collagen content is appreciated as a contributing feature to cardiac dysfunction in each of these pathologies. In addition, aging, is also associated with increases in cardiac collagen content. The importance of characterizing differences in ECM composition and processes used by cardiac fibroblasts in the assembly of fibrotic collagen accumulation is critical for the design of strategies to reduce and ultimately regress cardiac fibrosis. Collagen cross-linking is one factor that influences collagen deposition and insolubility with direct implications for tissue properties such as stiffness. In this review, three different types of collagen cross-links shown to be important in cardiac fibrosis will be discussed; those catalyzed by lysyl oxidases, those catalyzed by transglutaminases, and those that result from non-enzymatic modification by the addition of advanced glycation end products. Insight into cellular mechanisms that govern collagen cross-linking in the myocardium will provide novel pathways for exploring new treatments to treat diseases associated with cardiac fibrosis.
