Abstract

Osteoarthritis (OA) is a degenerative disease that affects various tissues surrounding joints such as articular cartilage, subchondral bone, synovial membrane, and ligaments. No therapy is currently available to completely prevent the initiation or progression of the disease partly due to poor understanding of the mechanisms of the disease pathology. Cartilage is the main tissue afflicted by OA, and chondrocytes, the sole cellular component in the tissue, actively participate in the degeneration process. Multiple factors affect the development and progression of OA including inflammation that is sustained during the progression of the disease and alteration in biomechanical conditions due to wear and tear or trauma in cartilage. During the progression of OA, extracellular matrix (ECM) of cartilage is actively remodeled by chondrocytes under inflammatory conditions. This alteration of ECM, in turn, changes the biomechanical environment of chondrocytes, which further drives the progression of the disease in the presence of inflammation. The changes in ECM composition and structure also prevent participation of mesenchymal stem cells in the repair process by inhibiting their chondrogenic differentiation. This review focuses on how inflammation-induced ECM remodeling disturbs cellular activities to prevent self-regeneration of cartilage in the pathology of OA.

摘要

骨关节炎(OA)是一种退行性疾病,影响关节周围的各种组织,如关节软骨、软骨下骨、滑膜和韧带。目前尚无完全预防疾病发生或进展的疗法,部分原因是对疾病发病机制的了解不足。软骨是 OA 主要受累的组织,软骨细胞是组织中唯一的细胞成分,积极参与退行性过程。多种因素影响 OA 的发生和发展,包括炎症在疾病进展过程中持续存在,以及由于软骨磨损或创伤导致的生物力学条件改变。在 OA 的进展过程中,软骨细胞在炎症条件下积极重塑细胞外基质(ECM)。这种 ECM 的改变反过来又改变了软骨细胞的生物力学环境,在炎症存在的情况下进一步推动了疾病的进展。ECM 组成和结构的变化也通过抑制间充质干细胞的软骨分化来阻止其参与修复过程。本综述重点讨论了炎症诱导的 ECM 重塑如何扰乱细胞活动,从而防止 OA 病理中软骨的自我再生。
