Background/Purpose: Rheumatoid arthritis (RA) is characterized by hyperplastic synovial pannus tissue, which mediates destruction of cartilage and bone. Fibroblast-like synoviocyte (FLS) are a key component…Abstract Number: 1413 • 2017 ACR/ARHP Annual Meeting
Cytokine-Induced Aire Activity in Rheumatoid Arthritis Fibroblast-like Synoviocytes Regulates Expression of Interferon-γ Response Genes
Background/Purpose: AIRE is a transcriptional regulator of tissue specific antigens in medullary thymic epithelial cells (mTEC). AIRE orchestrates the negative selection of self-reactive T cells…Abstract Number: 1414 • 2017 ACR/ARHP Annual Meeting
Stimulation with Resistin Upregulates Chemokine Production By Fibroblast-like Synoviocytes from Patients with Rheumtoid Arthritis
Background/Purpose: Adipose tissue synthesizes and releases physiologically active molecules that are known as adipokines. Resistin, an adipokine, has been widely studied the regulation of glucose…Abstract Number: 1415 • 2017 ACR/ARHP Annual Meeting
TNF-Induced IRF1 Is Critical for the Inflammatory Gene Expression in Fibroblast-like Synoviocytes
Background/Purpose: Fibroblast-like synoviocytes (FLS) are increasingly recognised as major pathogenic cells in synovial inflammation of patients with Rheumatoid Arthritis (RA). In response to pro-inflammatory stimuli,…Abstract Number: 1416 • 2017 ACR/ARHP Annual Meeting
Higher Expression of Type 1 Interferon in Synovitis of Patient with Undifferentiated Arthritis before They Met Rheumatoid Arthritis Criteria Compared to Established Rheumatoid Arthritis. a Retrospective Study with 14 Years of Follow-up
Background/Purpose: Undifferentiated Arthritis (UA) is defined as an inflammatory oligo/poly arthritis that does not fulfil criteria for a definitive diagnosis.Delay in diagnosis and treatment leads…Abstract Number: 1417 • 2017 ACR/ARHP Annual Meeting
Mitophagy Defect in Fibroblast-like Synoviocytes of Rheumatoid Arthritis Is Improved By Pyruvate Treatment
Background/Purpose: Fibroblast-like synoviocytes (FLS) in the synovial intimal lining produce pro-inflammatory cytokines resulting in increase of joint inflammation. Recent studies about the cellular metabolism in…Abstract Number: 1418 • 2017 ACR/ARHP Annual Meeting
The Value of Adalimumab Trough Levels and Clinical Assessments in Predicting Clinical Response in Patients with Established Rheumatoid Arthritis and an Inadequate Response to Methotrexate
Background/Purpose: Low trough levels of the tumor necrosis factor inhibitor, adalimumab (ADL), and anti-ADL antibodies (AAA) were reported to be correlated with lack of response…Abstract Number: 1419 • 2017 ACR/ARHP Annual Meeting
Characteristics of Patients with Early Rheumatoid Arthritis Who Have a Delayed Response to Treatment with Methotrexate in Monotherapy or in Combination with Adalimumab
Background/Purpose: In patients (pts) with rheumatoid arthritis (RA), treat-to-target recommendations call for adjustment of treatment if a target is not met within 3-6 months (mths)…Abstract Number: 1420 • 2017 ACR/ARHP Annual Meeting
