Macrophage Mediators of Autoimmune Valvular Carditis and Fibrosis
Background/Purpose: K/B.g7 TCR transgenic mice spontaneously develop both autoimmune arthritis and valvular carditis. We utilize this model to define mediators of rheumatic disease-associated cardiovascular inflammation…Abstract Number: 2077 • 2018 ACR/ARHP Annual Meeting
Pathological Osteogenesis and Inflammation in Experimental Spondyloarthritis Are Associated with Aberrant Type H Blood Vessels and Development of High Endothelial Venules Accompanied By Ectopic Lymphoid Structures in Bone Marrow
Background/Purpose: Spondyloarthritis (SpA) is characterized by pathological osteogenesis, inflammation and extensive angiogenesis in inflamed tissues. TNF plays a central role in SpA pathology and transgenic…Abstract Number: 1021 • 2018 ACR/ARHP Annual Meeting
Impact of TLR7 Ligation in RA Pathology
Background/Purpose: Expression of Toll-like receptor 7 (TLR-7) is highly elevated in rheumatoid arthritis (RA) and osteoarthritis (OA) compared to normal (NL) synovial tissue lining and…Abstract Number: 2082 • 2018 ACR/ARHP Annual Meeting
ERAP1 Deficiency Partially Relieves HLA-B27-Induced ER Stress and IL-23 Expression, but Does Not Restore Dendritic Cell Function in Experimental Spondyloarthritis
Background/Purpose: Preliminary results suggest that endoplasmic reticulum (ER) aminopeptidase 1 (ERAP1) deficiency partially protects HLA-B27/human b2m transgenic (B27-Tg) rats from spondyloarthritis (SpA) as evidenced by…Abstract Number: 1033 • 2018 ACR/ARHP Annual Meeting
Comparison of Oral Administration of Diacerein, Intra-Articular Injection of Diacerein Solution, and Intra-Articular Injection of Diacerein-Loaded Nanoparticle in Osteoarthritis Rat Model
Background/Purpose: Osteoarthritis (OA) treatment is typically administered to control symptoms. Diacerein (DIA) reduces interleukin (IL)-1 receptor on chondrocytes and prevents structural degradation of joint tissue.…Abstract Number: 2090 • 2018 ACR/ARHP Annual Meeting
Identification of a Role for Monocytes in Murine Lupus Associated Diffuse Alveolar Hemorrhage By Mass Cytometry
Background/Purpose: Diffuse alveolar hemorrhage (DAH) is a life-threatening pulmonary complication of systemic lupus erythematosus. The inciting pathology is thought to be pulmonary capillaritis but the…Abstract Number: 1034 • 2018 ACR/ARHP Annual Meeting
A Conplastic Mice Model of Aging Reveals That Mitochondrial DNA Variation Influences the Process of Joint Deterioration
Background/Purpose: Different studies showed interesting genetic associations between mtDNA haplogroups and OA-related features, including prevalence, incidence and progression of the disease. The aim of this…Abstract Number: 2096 • 2018 ACR/ARHP Annual Meeting
Ectonucleotidase CD73 Suppresses Autoantibody Production and Arterial Vasculopathy in Murine Lupus
Background/Purpose: CD73 is a surface nucleotidase that extends into the extracellular space where it generates adenosine from AMP. By regulating a cell’s “purinergic halo,” CD73…Abstract Number: 1039 • 2018 ACR/ARHP Annual Meeting
Tenofovir Induces Osteopenia and Dipyridamole, an Inhibitor of the Ent-1 Nucleoside Transporter, Reverses the Osteopenic Effect of Tenofovir In Vivo
Background/Purpose: Osteopenia and fragility fractures have been associated with HIV infection. Tenofovir, one of the most commonly used antivirals in HIV, also leads to increases…Abstract Number: 2103 • 2018 ACR/ARHP Annual Meeting
Using a Drosophila Model to Unravel the Genetic Complexity of Systemic Lupus Erythematosus
Background/Purpose: The objective of our research is to understand the genetic architecture and molecular mechanisms that contribute to the development and progression of the autoimmune…Abstract Number: 38 • 2018 ACR/ARHP Annual Meeting
Pre-Clinical Clonally-Expanded aggrecan89-103–Specific CD4+ T Cells Are a Target for Autoimmune Arthritis Prevention
Background/Purpose: In the pre-clinical rheumatoid arthritis (RA) prodrome, autoantibodies and transient symptoms may develop. Pre-clinical autoantibody development suggests concomitant expansion of autoantigen-specific CD4+ follicular helper…Abstract Number: 1076 • 2018 ACR/ARHP Annual Meeting
Phospholipase C-eta2, As a C2 Domain-Containing Protein, Regulate Aggressiveness of Fibroblast‐like Synoviocytes and Ameliorate Arthritis in Experimental Animal Models of Rheumatoid Arthritis
Background/Purpose: The C2 domain is a Ca2+-dependent membrane-targeting motif found in many cellular proteins involved in signal transduction or inflammatory pathway. However, the effects of…Abstract Number: 2451 • 2018 ACR/ARHP Annual Meeting
Herpes Zoster in Rheumatoid Arthritis. Prospective Single Center Study of 390 RA Patients for 5 YEARS
Background/Purpose: Immunosuppressed patients such as Rheumatoid Arthritis (RA) patients have a greater risk (1.5-2 times) of presenting herpes zoster (HZ). Both, the disease itself and…Abstract Number: 39 • 2018 ACR/ARHP Annual Meeting
Allogeneic Mesenchymal Stem Cells Derived Extracellular Vesicles As a Superior Immunosuppressant in Murine Arthritis Therapy
Allogeneic mesenchymal stem cells derived extracellular vesicles as a superior immunosuppressant in murine arthritis therapyRunci Wang1,2, Yi Liu2, Songtao Shi1Affiliation: 1. Department of Anatomy and…Abstract Number: 1115 • 2018 ACR/ARHP Annual Meeting
In Vivo Assessment of Prevention of Lung Fibrosis Using the Pan-PPAR Agonist Lanifibranor in the Tβriiδk-Fib Mouse Model of Systemic Sclerosis
Background/Purpose: The TbRIIDk-fib transgenic (TG) mouse model of scleroderma carries a fibroblast-specific transforming growth factor β (TGFβ) receptor II mutation resulting in balanced up-regulation of…
