Extracellular matrix protein (synovial tissue ECM component) (null)

The extracellular matrix proteins in synovial tissue comprise collagens (majority type II in cartilage, various types in synovium), elastin, fibronectin, laminin, proteoglycans (aggrecan, decorin, biglycan, fibromodulin), and glycosaminoglycans (e.g., hyaluronic acid)[2][3]. These proteins form a physical scaffold supporting synovial cells and mediating mechanical resilience, cell adhesion, migration, and signaling in joint tissue[2][3]. Synovial ECM stores and presents growth factors, cytokines, and chemokines to regulate immune and repair responses[2]. In synovial diseases, particularly arthritis, dysregulation or excessive degradation of the ECM drives tissue damage, chronic inflammation, fibrosis, and loss of joint function[1][2]. Modulating the ECM structure and turnover is an emerging therapeutic strategy in joint diseases, but safety and efficacy challenges remain[1][2]. Key point: “Extracellular matrix proteins in synovial tissue” is an umbrella term for many interrelated structural and regulatory proteins. It does not refer to a single target molecule and should be redefined for greater specificity when compiling target information.

Matrix metalloproteinase inhibitors block enzymes that degrade ECM proteins, aiming to limit cartilage/synovium damage in arthritis[1]. Hyaluronic acid injections supplement ECM function, improving joint lubrication and cushioning[2].
