Bimekizumab Dual Inhibition of IL-17A and IL-17F Provides Evidence of IL-17F Contribution to Chronic Inflammation in Disease-Relevant Cells
Background/Purpose: IL-17A and IL-17F share structural homology and have similar biologic function.1 Although the contribution of IL-17A to immune-mediated inflammatory diseases has been widely reported,1,2…Abstract Number: 1572 • 2017 ACR/ARHP Annual Meeting
MHC Associations of Ankylosing Spondylitis in East Asians Are Driven By HLA-B Amino-Acid Position 97, Confirming Findings in European Descent Subjects
Background/Purpose: Whilst HLA-B27 is the MHC allele associated with AS, there is strong evidence indicating that other HLA-B alleles and MHC genes are involved in…Abstract Number: 1573 • 2017 ACR/ARHP Annual Meeting
In Vivo Phosphorylation of p38 in Monocytes Is Enhanced in Patients with Axial Spondyloarthritis (axSpA) at the Time of Diagnosis
Background/Purpose: Host response to microbes is considered to contribute to the pathogenesis to axSpA and other HLA-B27 associated diseases. The p38 MAP kinase pathway plays…Abstract Number: 1574 • 2017 ACR/ARHP Annual Meeting
Gut Microbiota Perturbations in Reactive Arthritis
Background/Purpose: Reactive arthritis (ReA) is an inflammatory condition occurring several weeks after gastrointestinal (GI) or genitourinary (GU) infections. HLA-B27 positivity is considered a risk factor,…Abstract Number: 1575 • 2017 ACR/ARHP Annual Meeting
JMJD3 Epigenetically Regulate Ankylosing Spondylitis Inflammation through Th17 Differentiation
JMJD3 epigenetically regulate ankylosing spondylitis inflammation through Th17 differentiation Background/Purpose: Inflammation is the initial stage of ankylosing spondylitis (AS), looking for possible inflammatory regulator will…Abstract Number: 1576 • 2017 ACR/ARHP Annual Meeting
IL-23 Promotes Fecal Microbiota Dysbiosis Associated with Susceptibility to Spondyloarthritis and Ileitis in ZAP-70 Mutant SKG Mice
Background/Purpose: Identification of disease-associated or protective bacteria may elucidate new biomarkers or probiotic supplements for people suffering from SpA, or for people at-risk of disease…Abstract Number: 1577 • 2017 ACR/ARHP Annual Meeting
Deciphering the Role of the Tissue Microenvironment in Shaping the Immune Landscape in Psoriatic Arthritis
Background/Purpose: Psoriatic arthritis (PsA) occurs in a third of patients with psoriasis (Ps) and up to 30% of patients with PsA do not have an…Abstract Number: 1578 • 2017 ACR/ARHP Annual Meeting
The Initiation, but Not the Persistence, of Experimental Spondyloarthritis in HLA-B27/Huβ2m Transgenic Rats Is Crucially Dependent on the IL-23 Axis
Background/Purpose: IL-17A is a central driver of spondyloarthritis (SpA) pathology. IL-17A production was originally proposed to be IL-23 dependent. Emerging preclinical and clinical evidence from…Abstract Number: 1579 • 2017 ACR/ARHP Annual Meeting
Monocyte-Derived Dendritic Cells (MDDCs) from Spondyloarthritis (SpA) Patients Exhbit a Coordinated Downregulation of the Cholesterol (chol) Biosynthesis Pathway That Relates to Lipid Overload
Background/Purpose: Gene expression studies are useful to investigate the pathogenesis of complex diseases. The critical role of antigen-presenting cells such as dendritic cells (DCs) being…Abstract Number: 1580 • 2017 ACR/ARHP Annual Meeting
HLA-B27/ Human β2-Microglobulin (β2m) Transgenic Drosophila Expresses Specific Cross-Vein Less (CVL) and Small-Eye Phenotypes Resulting from Disruption of the BMP/TGFβ Signaling Pathway
Background/Purpose: The association between HLA-B27 and spondyloarthritis (SpA) remains unexplained more than 40 years after its discovery. To further explore the pathogenic role of HLA-B27,…Abstract Number: 1581 • 2017 ACR/ARHP Annual Meeting
Differential Involvement of Synovial and Entheseal Inflammation in Mediating Pathological IL23 Axis Signaling in Spondyloarthritis
