(author)Objective: Soluble mediators in synovial fluid (SF) are acknowledged as key players in the pathophysiology of osteoarthritis (OA). However, a wide-spectrum screening of such mediators in SF is currently lacking. In this study, the levels of 47 mediators in the SF of control donors and osteoarthritic (OA) patients were compared. Materials &...article 2013

de Lange-Brokaar, B.J.E. (author), Ioan-Facsinay, A. (author), van Osch, G.J.V.M. (author), Zuurmond, A.-M. (author), Schoones, J. (author), Toes, R.E.M. (author), Huizinga, T.W.J. (author), Kloppenburg, M. (author)Objective: Although osteoarthritis (OA) is considered a non-inflammatory condition, it is widely accepted that synovial inflammation is a feature of OA. However, the role of immune cells and their cytokines in OA is largely unknown. This narrative systematic review summarizes the knowledge of inflammatory properties, immune cells and their...article 2012

Vos, P.A.J.M. (author), Degroot, J. (author), Barten-Van Rijbroek, A.D. (author), Zuurmond, A.-M. (author), Bijlsma, J.W.J. (author), Mastbergen, S.C. (author), Lafeber, F.P.J.G. (author)Osteoarthritis is a highly prevalent disease, age being the main risk factor. The age-related accumulation of advanced-glycation-endproducts (AGEs) adversely affects the mechanical and biochemical properties of cartilage. The hypothesis that accumulation of cartilage AGEs in combination with surgically induced damage predisposes to the...article 2012

(author)Objectives: Obesity is a risk factor for the development of osteoarthritis (OA) in hands and knees. Adipose tissue can secrete different adipokines with powerful immunomodulatory effects. The infrapatellar fat pad (IFP) is an intra-articular organ in the vicinity of the synovium and cartilage. It is hypothesised that IFP-derived soluble factors...article 2011

(author), Mastbergen, S.C. (author), TNO Kwaliteit van Leven (author)In osteoarthritis (OA), cartilage degradation is accompanied by subchondral bone changes. The pathogenesis and physiology of bone changes in OA are still unclear. The changes in subchondral bone architecture and cartilage damage were compared in differently induced experimental models of OA. Experimental OA was induced bilaterally by anterior...article 2010

(author), TNO Kwaliteit van Leven (author)In studies aimed at local treatment of experimental osteoarthritis (OA) it is optimal to have an internal (untreated) OA control. Such an approach excludes interanimal variation, and allows paired statistical evaluation of treatment efficacy. For this purpose, we developed and characterized a bilateral version of the canine Groove model. We...article 2008
