To investigate both the involvement of chemokines in general and the relative importance of specific chemokines in rheumatoid arthritis (RA), we characterized the effect of the monokines tumor necrosis factor alpha (TNF alpha) and interleukin-1 beta (IL-1 beta) on the synthesis of neutrophil-activating factors by synovial fibroblasts isolated from the joints of patients with RA.
Pairwise-tagging single nucleotide polymorphisms (SNPs) spanning 24 candidate genes were selected and genotyped in a large UK cohort of patients receiving anti-TNF therapy for RA.
Presence of anti-cyclic citrullinated peptide antibodies is associated with better treatment response to abatacept but not to TNF inhibitors in patients with rheumatoid arthritis: a meta-analysis.
This study identifies a potentially important role for TNF-αrs1800629 polymorphisms in the susceptibility to RA.However, further studies in larger cohorts are required.
Variations in two genes of the tumour necrosis factor (TNF) alpha pathway have been implicated in the pathogenesis of autoimmune diseases: polymorphisms in the TNFRSF1A gene, encoding TNF receptor 1, showed significant association with MS in genomewide association scans, and variation in or near the TNFAIP3 gene, coding for a negative regulator of NFkB, was associated with MS, systemic lupus erythematosus, diabetes and rheumatoid arthritis.
TCZ-SC, alone or with a csDMARD, yielded rapid and sustained efficacy in DMARD/anti-TNFα-IR RA patients, with acceptable toxicity.Home administration seems feasible.
At baseline, TTP and HuR gene expression levels, as well as the TTP:TNFalpha, TTP:HuR, and TIA-1:TNFalpha gene expression ratios were lower in patients with RA than in control subjects, while expression of TNFalpha, TIA-1, and TIA-1:HuR was higher in patients with RA.
Gene-environment associations are important in rheumatoid arthritis (RA) susceptibility, with an association existing between smoking, HLA- DRB1 'shared epitope' alleles, PTPN22 and antibodies to cyclic citrullinated peptides (CCP).
In contrast with a study of American patients with RAno evidence of association with PTPN22 independent of the well-characterised R620W variant was found, suggesting that in these patients this variant alone explains the association with the PTPN22 gene.
PreproET mRNA expression increased in PBMCs from rheumatoid arthritis (RA) patients but returned to basal level in PBMCs from patients under anti-TNF therapy.
Many therapies are now available for patients with rheumatoid arthritis (RA) who have an inadequate response to methotrexate including tumor necrosis factor inhibitors, abatacept, tocilizumab, and rituximab.
Conversely, Th17 cells and their effector molecules interleukin 17A (IL-17A), IL-17F, interferon (IFN)γ, tumor necrosis factor (TNF)α, and granulocyte-macrophage colony-stimulating factor (GM-CSF) are implicated in the pathology of rheumatoid arthritis (RA).
The autoimmune-associated genetic variant PTPN22R620W enhances neutrophil activation and function in patients with rheumatoid arthritis and healthy individuals.
This study investigated the added value of US to clinical variables in predicting flare in RA patients with longstanding low disease activity when stopping TNF inhibitors (TNFi).
These results exclude the possibility of involvement of the TNFA genes (TNF-alpha) in the development of RA, which was suggested previously to be a strong candidate for RA in the class III region.
Eighty-one patients with active RA were genotyped for the -308 TNFalpha polymorphism by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis and subdivided into two groups for each polymorphism (G/A and G/G genotype).
To evaluate the efficacy and safety of interleukin 17 (IL-17) inhibitors in two rheumatoid arthritis (RA) populations: biologic-naïve or tumor necrosis factor inhibitor inadequate responders (TNF-IR).
A functional variant of protein tyrosine phosphatase nonreceptor 22 (PTPN22) has recently been shown to be associated with multiple autoimmune diseases, including systemic lupus erythematosus (SLE), rheumatoid arthritis, type 1 diabetes, and autoimmune thyroid disease.
Mycobacterial diseases are prevalent in cancer and rheumatoid arthritis (RA) patients, especially those receiving tumor necrosis factor-α inhibitor (TNFi).
