Synovitis biomarkers: ex vivo characterization of three biomarkers for identification of inflammatory osteoarthritis
نویسندگان
چکیده
OBJECTIVE Characterize biomarkers measuring extracellular matrix turnover of inflamed osteoarthritis synovium. METHODS Human primary fibroblast-like synoviocytes and synovial membrane explants (SMEs) treated with various cytokines and growth factors were assessed by C1M, C3M, and acMMP3 in the conditioned medium. RESULTS TNFα significantly increased C1M up to seven-fold (p = 0.0002), C3M up to 24-fold (p = 0.0011), and acMMP3 up to 14-fold (p < 0.0001) in SMEs. IL-1β also significantly increased C1M up to five-fold (p = 0.00094), C3M four-fold (p = 0.007), and acMMP3 18-fold (p < 0.0001) in SMEs. CONCLUSION The biomarkers C1M, C3M, and acMMP-3 were synovitis biomarkers ex vivo and provide a translational tool together with the SME model.

Background: Osteoarthritis is one of the most commonly diagnosed malignant diseases in the world and was previously recognized as a degenerative joint disease characterized by cartilage deformity and the formation of new bones at the edges of the joint. But this disease is not just a degenerative disease but also a biomechanical, biochemical, and cellular phenomenon. Common treatments include s...

Introduction: Osteoarthritis is a common and painful joint disease with unknown etiology. Interleukin 10 (IL-10) and Alfa tumor necrosis factor (TNF-α) are considered as the main factors regulating inflammation and pathology of knee osteoarthritis. This study aimed to investigate the effects of mesenchymal stem cells (MSCs) and aerobic training on inflammatory biomarkers (IL-10, TNF- α) in the ...

HTLV-1 is the causative agent for a neurologic disease named HTLV-I- associated myelopathy/tropical spastic paraparesis (HAM/TSP). Paraparesis of the lower limbs which appears gradually is the most common clinical feature of this disease. It has been shown that the indirect involvement of the nervous system by lymphocytes is more probable than the direct attack of the virus to the neurons. HTLV...

Background: Crohn's disease (CD) is a type of inflammatory bowel disease (IBD) which despite the unknown details is generally related to genetic, immune system, and environmental factors. In this study, we identify transcriptional signatures in patients with CD and then explain the potential molecular mechanisms in inflamed and non-inflamed intestinal mucosa in these patients. Materials and Me...
