However, it is also evident that anti-TNF therapy is not effective in all patients and that many responders still present residual signs of active disease. In order to improve the treatment of chronic arthritis, a further search for additional potential ta[r]
For example, it has been demonstrated that sympathetic nerve fibers are lost in inflamed tissue of patients with RA (reviewed in [4]). In parallel, sensory nerve fibers containing the major proinflammatory neuropeptide substance P sprout into inflamed tissue (revie[r]
Results Serum samples were available in 18,658 patients: 3,116 patients with RA, 1,063 with polyarthritis or oligoarthritis, 818 with spondylarthropathy, 2,736 with osteoarthritis, and 10,925 classified as other. A second sample was available in 1,524 patients with RA, 419 with polya[r]

Rheumatoid arthritis (RA) remains a prevalent disease worldwide that causes significant morbidity and mortality despite recent thera- peutics. High mobility group box-1 (HMGB1) protein, originally appreciated as an intranuclear DNA binding protein, has been implicated as an integral me[r]
FACS analysis was used for IFN- γ and IL-4 analysis at the single cell level. After cells had been cultured for 10 days they were extensively washed, were seeded at a concen- tration of 10 6 cells/ml and were stimulated with iono- mycin/phorbol myristate acetate for 6 hours. To enhance[r]
If we are to fully exploit the information and methods that are emerging from the ENCODE project to under- stand the pathology of RA at the molecular level, then we have very likely reached the limits of what we can achieve while studying mixed po[r]
Objectives: To evaluate serum levels of interleukin (IL)-6 in rheumatoid arthritis (RA) patients and to assess the correlations of this cytokine with clinical and laboratory parameters. Subjects and methods: 86 patients with RA and 30 healthy volunteers were enrolled in the study.
Introduction The synovial membrane is a thin lining layer within the joint cavity that is responsible for maintaining normal joint func- tion and homeostasis. Within the synovial membrane, the cells most closely associated with this homeostatic func- tion are the[r]
GC-induced hyperglycaemia is a well-recognised complica- tion of long-term GC use [64]. It is known that patients with active RA have impaired glucose handling and that glucose metabolism may be affected directly or indirectly by inflamma- tory mediators [65]. Several studies have demonstra[r]
Discussion Our results demonstrate that RasGRF1 regulates spontane- ous MMP-3 production in RA FLS, and suggest that overex- pression of RasGRF1 sensitizes signaling pathways promoting MMP-3 production and joint destruction in RA. RasGRF1 specifically activates H-Ras, but no[r]
The bone destruction disease including osteoporosis and rheumatoid arthritis are caused by the imbalance between osteoblastogenesis and osteoclastogenesis. Inhibition of the NF-κB pathway was responsible for decreased osteoclastogenesis.
This prospective study was designed to analyze the incidence and the factors associated with impairment in left ventricular systolic function (LVSF) overtime in patients with rheumatoid arthritis (RA) without overt cardiac disease. In particular, we verified the hypothesis that a relationship betwee[r]
Although we were not able to test this hypothesis directly in our data (because the relevant reproductive variables were not available), a review of the literature gives some clues. In studies conducted in women-only cohorts, the presence of as[r]

It is intriguing to speculate that alterations in Src-PTK/FAK complex formation are present in RA-SFs, and it is clear that this aspect of fibroblasts activation requires further attention. By focusing on cytoskeletal rearrangement and cell migration, Zeng and coworkers [4] addr[r]
