Unmethylated CpG motifs are often found in bacterial DNA, and exert immunostimulatory effects on hematopoietic cells. Bacteria produce severe joint inflammation in septic and reactive arthritides; bacterial DNA may be involved in this process. We injected bacterial DNA originating from Escherichia coli and Staphylococcus aureus and oligonucleotides(More)
Tumor necrosis factor (TNF)-alpha has an important role in the pathogenesis of autoimmune and inflammatory diseases such as rheumatoid and septic arthritis. The biological effects of TNF-alpha are mediated by binding to TNF receptors TNFR1 (also known as P60) or TNFR2 (also known as P80). The pre-ligand assembly domain (PLAD) is a portion of the(More)
Staphylococcus aureus is one of the most important pathogens in septic arthritis. To analyse the arthritogenic properties of staphylococcal peptidoglycan (PGN), highly purified PGN from S. aureus was intra-articularly injected into murine joints. The results demonstrate that PGN will trigger arthritis in a dose-dependent manner. A single injection of this(More)
Tumor necrosis factor (TNF)-alpha is an important proinflammatory cytokine and plays a crucial role in pathogenesis of inflammatory arthritis, such as rheumatoid and septic arthritis. TNFalpha exerts its effect by binding to the extracellular domain of TNF receptor (TNFR) 1 and 2. The amino-terminal portion of the TNFR extracellular domain, known as(More)
