Abstract

Intervertebral disc degeneration (IDD) is the most common diagnosis in patients with low back pain, a leading cause of musculoskeletal disability worldwide. The major components of extracellular matrix (ECM) within the discs are type II collagen (Col II) and aggrecan. Excessive destruction of ECM, especially loss of Col II and aggrecan, plays a critical role in promoting the occurrence and development of IDD. Matrix metalloproteinases (MMPs) and a disintegrin and metalloprotease with thrombospondin motifs (ADAMTSs) are primary enzymes that degrade collagens and aggrecan. There is a large and growing body of evidence that many members of MMPs and ADAMTSs are highly expressed in degenerative IVD tissue and cells, and are closely involved in ECM breakdown and the process of disc degeneration. In contrast, targeting these enzymes has shown promise for promoting ECM repair and mitigating disc regeneration. In the current review, after a brief description regarding the biology of MMPs and ADAMTSs, we mainly focus on their expression profiles, roles and therapeutic potential in IDD. A greater understanding of the catabolic pathways involved in IDD will help to develop potential prophylactic or regenerative biological treatment for degenerative disc disease in the future.

摘要

椎间盘退变(IDD)是下腰痛患者最常见的诊断结果,下腰痛是全球肌肉骨骼残疾的主要原因。椎间盘内细胞外基质(ECM)的主要成分是II型胶原蛋白(Col II)和聚集蛋白聚糖。ECM的过度破坏,尤其是Col II和聚集蛋白聚糖的丢失,在促进IDD的发生和发展中起关键作用。基质金属蛋白酶(MMPs)和具有血小板反应蛋白基序的解聚素和金属蛋白酶(ADAMTSs)是降解胶原蛋白和聚集蛋白聚糖的主要酶。大量且不断增加的证据表明,MMPs和ADAMTSs的许多成员在退变的椎间盘组织和细胞中高度表达,并密切参与ECM的分解和椎间盘退变过程。相比之下,针对这些酶已显示出促进ECM修复和减轻椎间盘退变的前景。在当前综述中,在简要描述MMPs和ADAMTSs的生物学特性后,我们主要关注它们在IDD中的表达谱、作用和治疗潜力。对IDD所涉及的分解代谢途径有更深入的了解将有助于未来开发针对退行性椎间盘疾病的潜在预防性或再生性生物治疗方法。
