The Prevalence of Anti-DFS70 Antibodies in an International Inception Cohort of Systemic Lupus Erythematosus
Background/Purpose: Autoantibodies to the nuclear autoantigen dense fine speckles 70 (DFS70) are associated with a new paradigm whereby when they are found in isolation (monospecific…Abstract Number: 773 • 2015 ACR/ARHP Annual Meeting
Clinical Evaluation of Patients with Positive Antibodies to Extractable Nuclear Antigens but Negative ANA
Background/Purpose: In the setting of a negative ANA, antibodies to extractable nuclear antigens (ENA) should be correspondingly negative, but alternative clinical scenarios occasionally arise. This…Abstract Number: 774 • 2015 ACR/ARHP Annual Meeting
Anti-Nuclear Antibodies Have High Sensitivity for Systemic Lupus Erythematosus: Results of a Systematic Literature Review and Meta-Regression of Diagnostic Data

DNA Sensors Regulate Inflammation in a Model of Autoimmune Arthritis
Background/Purpose: Innate immune sensors such as cytosolic DNA sensors and toll-like receptors (TLRs) detect viral or bacterial DNA, resulting in production of proinflammatory cytokines and…Abstract Number: 1644 • 2014 ACR/ARHP Annual Meeting
Mycophenolic Acid and Ribavirin Induces Cytoplasmic Autoimmunogenic Rods and Rings Structures in Vivo
Background/Purpose Autoantibodies to IMPDH2 occur in Hepatitis C patients receiving ribavirin (RBV) & interferon-α (IFN-α). Anti-IMPDH2 antibodies recognize “rods and rings” (RR) cytoplasmic structures in…Abstract Number: 1638 • 2014 ACR/ARHP Annual Meeting
