Peripheral Blood B Cells Are Expanded and Their Cytokine Expression Is Dysregulated in Juvenile Dermatomyositis
Background/Purpose: Juvenile dermatomyositis (JDM) is a rare form of childhood autoimmune myositis that presents with proximal muscle weakness and heliotrope rash. B cells are strongly…Abstract Number: 2104 • 2016 ACR/ARHP Annual Meeting
Treatment with Tocilizumab Decreases CXCL13 Expression in Cultured Temporal Arteries from Patients with Giant Cell Arteritis
Background/Purpose: IL-6 has been considered a biomarker of disease activity in GCA and a potential therapeutic target. However, the functional role of IL-6 in GCA…Abstract Number: 2105 • 2016 ACR/ARHP Annual Meeting
Autoimmune Pancreatitis-Associated Autoantigens Among 100 IgG4-Related Diseases Patients
Background/Purpose: IgG4-related disease (IgG4-RD) is a fibroinflammatory disorder of uncertain etiology. Recognition of this disease as a distinct entity stemmed from investigation into autoimmune pancreatitis…Abstract Number: 2106 • 2016 ACR/ARHP Annual Meeting
Regulation of Marginal Zone B Cell Differentiation By microRNA-146a
Background/Purpose: B cell development in the bone marrow is followed by specification into several functional subsets in the spleen, including marginal zone B (MZB) cells…Abstract Number: 2107 • 2016 ACR/ARHP Annual Meeting
Targeting Mir-155 in Rheumatoid Arthritis B Cells Reduces Antibody Production
Background/Purpose: Better understanding of epigenetic regulatory mechanisms in RA pathogenesis will facilitate the development of new biomarkers or therapeutic strategies. MicroRNAs are post-transcriptional regulators that…Abstract Number: 2108 • 2016 ACR/ARHP Annual Meeting
DNA Hypomethylation in Promoter Region of Zbtb38 Gene Ultimately Leads to Downregulated Expression of Anti-Inflammatory IL1r2 in Experiential Model of Rheumatoid Arthritis
Background/Purpose: Interleukin 1 beta (IL1B) is a multifunctional cytokine that is highly expressed in rheumatoid arthritis (RA) and drives pro-inflammatory pathways via interleukin 1 receptor…Abstract Number: 2109 • 2016 ACR/ARHP Annual Meeting
Immunoprofiling of Bruton’s Tyrosine Kinase (Btk)/Tec Family Kinase Inhibitors Indicate Activities Beyond Btk in Immunocyte Function
Background/Purpose: CC-292, CC-90008, and ibrutinib are covalent Btk/Tec family kinase inhibitors that block Btk activity by binding with high affinity to the adenosine triphosphate (ATP)…Abstract Number: 2110 • 2016 ACR/ARHP Annual Meeting
Synovial Fibroblasts Regulate B Cell Survival Via B Cell Activating Factor of the TNF Family (BAFF)
Background/Purpose: In rheumatoid arthritis (RA), synovial fibroblasts (SF) are one main contributor of joint destruction since they resist apoptosis and secrete pro-inflammatory cytokines and matrix…
