Myosin Regulation of TNF Receptor 2 Signaling May Contribute to Anti-TNF Therapy Response
Background/Purpose: Background/Purpose:Anti-TNF agents have revolutionized the clinical outcomes of patients with rheumatoid and psoriatic diseases. However, up to 40% of patients do not respond or…Abstract Number: 1770 • 2019 ACR/ARP Annual Meeting
Experimental Rheumatoid Joint Ameliorated by CRISPR Interference Targeting Long Non-coding RNA H19 Through Wnt Signaling Inactivation
Background/Purpose: Long non-coding RNAs (lncRNAs) participate in the rheumatoid arthritis (RA) pathogenesis. The aim of this study was to examine the lncRNA H19 and HOTAIR…Abstract Number: 1771 • 2019 ACR/ARP Annual Meeting
MyD88 S209R Enhances Inflammation in Mouse Models of Arthritis
Background/Purpose: MyD88 is a critical adaptor protein that connects Toll-like and IL-1 receptor signaling to activation of NF-kB. We previously reported a heterozygous de novo gain-of-function mutation in MYD88 (S222R)…Abstract Number: 1772 • 2019 ACR/ARP Annual Meeting
Chronotherapy Using Baricitinib Attenuates Collagen-induced Arthritis in Mice

The Card9-Neutrophil Signaling Axis Is Critical to Induction of Th17-Mediated Arthritis in SKG Mice
Background/Purpose: Caspase recruitment domain-containing protein 9 (CARD9) is an adaptor protein downstream of C-type lectin receptor signaling within myeloid cells. CARD9 is critical for anti-fungal immunity;…Abstract Number: 1774 • 2019 ACR/ARP Annual Meeting
Potential Involvement of OX40 Expressing Tfh Cells on Regulation of Autoantibody Sialylation in Experimental and Rheumatoid Arthritis
Background/Purpose: Recently, IL-23-Th17 cells axis and hyposialylation of antibodies were proved to be linked to experimental and rheumatoid arthritis. However it remains uncertain how Tfh,…Abstract Number: 1775 • 2019 ACR/ARP Annual Meeting
Cholesterol Sequestering in Macrophages Contributes to the Lipid Paradox in Chronic Arthritis
Background/Purpose: Patients with active rheumatoid arthritis (RA) have increased cardiovascular mortality, paradoxically associated with reduced circulating lipid levels. Several disease-modifying antirheumatic drugs (DMARDs), such as…Abstract Number: 1776 • 2019 ACR/ARP Annual Meeting
Causal Effect of TNF-α, IL-12p70, IL-17 Levels on the Risk of Psoriatic Arthritis: A Mendelian Randomization Study
Background/Purpose: Biologic agents targeting cytokines including TNF-α, IL-12p70 and IL-17 have been proven to be very effective in treating psoriatic arthritis (PsA). Nonetheless, whether these…Abstract Number: 1777 • 2019 ACR/ARP Annual Meeting
The Deubiquitinase TRABID Is a Potential Therapeutic Target in Spondyloarthritis
Background/Purpose: Interleukin 12 (IL-12) and 23 (IL-23) may play a pivotal role in the pathogenesis of inflammatory diseases, including Spondyloarthritis (SpA). In mice, the deubiquitinase…Abstract Number: 1778 • 2019 ACR/ARP Annual Meeting
Entheseal CD90+ SOX9+ Cartilage-like Cells Initiate Spinal Ankylosis in Ankylosing Spondylitis
Background/Purpose: Enthesitis is characterized by inflammation at the interface where tendon or ligament attaches to the bone and is a representative symptom of ankylosing spondylitis(AS).…Abstract Number: 1779 • 2019 ACR/ARP Annual Meeting
CLEC5A/MDL-1 Is Critical for Inflammatory Arthritis and Skin Inflammation
Background/Purpose: Interleukin-23 (IL-23) and its cognate receptor interleukin-23R (IL-23R):IL-12Rβ1 plays a critical role in the pathogenesis of autoimmune diseases including psoriasis and psoriatic arthritis. Although…Abstract Number: 1780 • 2019 ACR/ARP Annual Meeting
Microbiome in Offspring of Ankylosing Spondylitis Patients
Background/Purpose: Spondyloarthritis (SpA) results from the interplay between genetic and environmental factors. An emerging factor is the human intestinal microbiota, which multiple studies in children…Abstract Number: 1781 • 2019 ACR/ARP Annual Meeting
Cytokine Dependence of Enthesis-resident Lymphocytes in Murine Spondyloarthritis
Background/Purpose: Enthesis-resident CD4-CD8- double-negative (DN) T cells have been implicated in the pathogenesis of spondyloarthritis. Overexpression of IL-23 in adult mice activates these cells to…Abstract Number: 1782 • 2019 ACR/ARP Annual Meeting
A Human SLE Variant NCF1-R90H Drives Lupus-like Kidney Disease in a Pristane-induced Murine Lupus Model
Background/Purpose: We previously identify a p.Arg90His (p.R90H) substitution encoded in phagocyte neutrophil cytosolic factor (NCF1) as a novel risk variant for SLE, with decreased and…
