An increasing number of studies show that besides the inherited genetic architecture (that is, genomic DNA), various environmental factors significantly contribute to the etiology of rheumatoid arthritis. Epigenetic factors react to external stimuli and form bridges between the environment and the genetic information-harboring DNA. Epigenetic mechanisms are implicated in the final interpretatio...
OBJECTIVE To investigate the direct effect of joint innervation on immune mediated joint inflammation in a patient with psoriatic arthritis (PsA). CASE REPORT The patient developed arthritis mutilans in all digits of both hands with the exception of the left 4th finger, which had prior sensory denervation following traumatic nerve dissection. Plain radiography, ultrasonography and nerve condu...
Destruction of bone tissue by osteoclasts represents a severe pathological phenotype during inflammatory arthritis and results in joint pain and bone malformations. Previous studies have established the essential role of cytokines including TNFα and receptor-ligand interactions, such as the receptor activator of nuclear factor-kappa B-receptor activator of nuclear factor-kappa B ligand interact...
Autoantibodies and the immunoreceptors to which they bind can contribute to the pathogenesis of autoimmune diseases such as rheumatoid arthritis (RA). Spleen Tyrosine Kinase (Syk) is a non-receptor tyrosine kinase with a central role in immunoreceptor (FcR) signaling and immune cell functionality. Syk kinase inhibitors have activity in antibody-dependent immune cell activation assays, in precli...
There is an increasing evidence suggesting the role of fork head boxP3 (FoxP3) in the development and the regulation of CD4(+)CD25(+) Treg cells. T-cell regulatory mechanisms in rheumatoid arthritis patients were evaluated by the contributing factors such as pro-inflammatory cytokines, circulating immune complexes, HLA DR expression, ligand binding biomarkers, FoxP3 expression in paired samples...
background: the effectiveness of t cell vaccination has been demonstrated in a variety of animal models of both induced and spontaneous autoimmune diseases. objective: the purpose of this study was to test the t cell vaccination protocol to treat and prevent collagen induced arthritis (cia) in a rheumatoid arthritis model. methods: cia was induced by an intradermal injection of an artheritogen ...
IL-1 receptor antagonist-deficient (IL-1Ra(-/-)) mice spontaneously develop autoimmune arthritis. We demonstrate here that T cells are required for the induction of arthritis; T cell-deficient IL-1Ra(-/-) mice did not develop arthritis, and transfer of IL-1Ra(-/-) T cells induced arthritis in nu/nu mice. Development of arthritis was also markedly suppressed by TNF-alpha deficiency. We found tha...
An assay for the detection and quantitation of immune complexes is described. Experimental immune complexes or aggregated human gamma globulin (AHG) were incubated with polymorphonuclear leukocytes (PMN). After challenge of the PMN with opsonized zymosan, chemiluminescence was recorded in a scintillation spectrometer. A quantitative inhibition of chemiluminescence could be demonstrated by the i...
Elderly patients with rheumatoid arthritis, psoriasis and psoriatic arthritis encompass those elderly-onset disease, over 60 years of age, but also earlier disease onset who entered old age. Considering the age-related changes immune system, possible frailty, susceptibility to infection concomitant comorbidity that implies multiple medicines, treatment these diseases in elderly can be challengi...
The class of immune response against autoantigens could profoundly influence the onset and/or outcome of autoimmune diseases. Until now, there is only limited information on the antigen-specific balance between proinflammatory and regulatory responses in humans. Here we analyzed the natural immune response against a candidate autoantigen in rheumatoid arthritis, human cartilage glycoprotein-39 ...
