Synovial cells from a patient with rheumatoid arthritis produce osteoclastogenesis inhibitory factor/osteoprotegerin: reciprocal regulation of the production by inflammatory cytokines and basic fibroblast growth factor. These cells can differentiate into adipocytes, osteoblasts, and chondrocytes. dsm@medmail.com.cn. Synovial fibroblasts (SFs) play an important role in the inflammatory process of the synovium. Background/Purpose: The synovial inflammation observed in Rheumatoid Arthritis (RA) and Psoriatic Arthritis (PsA) is characterised by synovial fibroblast hyperplasia, leukocyte infiltration, neoangiogenesis and hypoxia. JAK inhibitors have shown to be an efficient therapeutic option in RA treatment, but less is known about the effect of JAK inhibitors on activated RASF. Fibroblast activation protein (FAP), as described so far, is a type II cell surface serine protease expressed by fibroblastic cells in areas of active tissue remodelling such as tumour stroma or healing wounds. These rheumatoid arthritis synovial fibroblasts (RASFs) constitute a quite unique cell type that distinguishes RA from other inflammatory conditions of the joints. Full text.

We examined the effects of phase of RA and disease outcome (resolving vs persistence) on fibroblast crosstalk with EC and regulation of lymphocyte recruitment. 1997; 240: 279 –86. Methods. Using fibroblasts from patients with self-limiting spontaneously resolving arthritis or RA, we were able to see what effect acute vs persistent inflammation has on fibroblast communication with endothelial cells. Previous reports have shown that RA-FLSs have proliferative features similar to cancer cells, in addition to causing cartilage erosion that eventually causes joint damage. Gui H(1), Liu X, Wang ZW, He DY, Su DF, Dai SM. Then, 3‐methyladenine was used as an autophagy inhibitor and bafilomycin A1 … Kuo et al . 19:365-372. Related articles in. Surprisingly, little is known about how the development of rheumatoid arthritis (RA) alters these immunomodulatory properties. PIM-1 kinase is a novel regulator of proinflammatory cytokine-mediated responses in rheumatoid arthritis fibroblast-like synoviocytes. Interleukin-6 and soluble interleukin-6 receptors in the synovial fluids from rheumatoid arthritis patients are responsible for osteoclast-like cell formation. In earlier studies, researchers found that CD34(+) cells in RA patients are regulated by TNFß and can differentiate into fibroblast-like cells, suggesting that bone marrow CD34+ could be the origin of RASFs [24]. 2005; 52 (7):1999–2002.
