T Helper 17 Cells and Interferon Type I: Partners In Crime In SLE?
Background/Purpose: A hallmark of systemic autoimmune diseases, such as systemic lupus erythematotsus (SLE), is the increased expression of interferon (IFN) type I inducible genes, the…Abstract Number: 628 • 2013 ACR/ARHP Annual Meeting
Estrogen Modulates The Expression Of Endosome-Associated Toll-Like Receptor 8 Through Estrogen Receptor-α Which May Contribute To Sex-Bias In Systemic Lupus Erythematosus
Background/Purpose: Epidemiological data suggests that females of child-bearing age are more resistant to infectious disease. The sex hormone estrogen (E2) is present at elevated levels…Abstract Number: 632 • 2013 ACR/ARHP Annual Meeting
Anti-Ribosomal-Phosphoprotein Autoantibodies Penetrate Into Neuronal Cells Via Neuron Growth Associated Protein (GAP43)
Background/Purpose: Autoantibodies targeting ribosomal phosphoproteins (anti-Ribos.P) are detected in the sera of 10-45% patients with neuropsychiatric-systemice-lupus-erythemathosus-(NPSLE) and correlate with disease-activity. Intracerebroventricular administration of anti-Ribos.P induce…Abstract Number: 638 • 2013 ACR/ARHP Annual Meeting
Estrogen-Induced STAT1 and STAT4 Expression Is Estrogen Receptor α Dependent and IFNα Independent: A Novel Mechanism For Sex-Bias In Systemic Lupus Erythematosus Pathogenesis?
Background/Purpose: Systemic Lupus Erythematosus (SLE) is a devastating multi-organ autoimmune disease displaying an overwhelming female predilection. Estrogen (E2) influences gene expression by binding to estrogen…Abstract Number: 547 • 2013 ACR/ARHP Annual Meeting
Anti Ribosomal P Antibodies Accelerate Lupus Glomerulonephritis and Induce Lupus Nephritis In Naive Mice
Background/Purpose: Circulating anti-phosphoribosomal protein antibodies (anti-Ribos.P) were found to be associated with lupus nephritis. We have assessed the direct role of anti-Ribos.P in the development…Abstract Number: 979 • 2012 ACR/ARHP Annual Meeting
Cell-Type Specific Type I Interferon Signatures in Systemic Lupus Erythematosus and Viral Infection: What Makes the Difference?
Background/Purpose: Gene expression profiling experiments using peripheral blood mononuclear cells (PBMCs) revealed a crucial role of type I interferon (IFN) in the pathogenesis of systemic…Abstract Number: 685 • 2012 ACR/ARHP Annual Meeting
Using a Library of Synthetic Autoantigen Mimics to Discover Biomarkers of Systemic Lupus Erythematosus
Background/Purpose: The natural history of systemic lupus erythematosus (SLE) is felt to evolve from a state of normal immunity to serologic autoimmunity and then…Abstract Number: 686 • 2012 ACR/ARHP Annual Meeting
Cell-Type Specific Type I Interferon Signatures in Autologous Stem Cell Transplanted Lupus Patients: Different Molecular Behavior Between CD4+ T Cells and Monocytes
Background/Purpose: Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that affects multiple organs, whose pathology is mainly caused by the augmented interferon (IFN)…Abstract Number: 670 • 2012 ACR/ARHP Annual Meeting
Prolidase Deficiency Induces Antibodies to Sm, Ro60 and Double Stranded DNA
Background/Purpose: Prolidase is a ubiquitous enzyme found in the cytoplasm. The enzyme specifically cleaves dipeptides containing C-terminal proline or hydroxyproline, in one of the last…Abstract Number: 201 • 2012 ACR/ARHP Annual Meeting
High Rate of Autoimmune Manifestations During Idiopathic CD4 Lymphocytopenia
Background/Purpose: When first described by the Center for Disease Control, idiopathic CD4 lymphocytopenia (ICL) was characterized by opportunistic infections in patients with a CD4 count≤300/mm3…Abstract Number: 27 • 2012 ACR/ARHP Annual Meeting
Anti-Citrullinated Protein Antibodies As an Indicator of Bone Damage in the Citrullinated Collagen Induced Arthritis Model
Background/Purpose: Although the pathogenesis and cause of rheumatoid arthritis (RA) remains uncertain, various disease-driving auto-antigens and auto-antibodies with different specificities have been used as diagnostic…Abstract Number: 2530 • 2012 ACR/ARHP Annual Meeting
Anti-Ribosomal P Antibodies in a Large Cohort of Autoimmune Hepatitis with No Evidence of Lupus: A Common Underlying Mechanism Targeting Liver?
Background/Purpose: Anti-ribosomal P proteins antibody (anti-rib P) is a highly specific marker for systemic lupus erythematosus (SLE) and it is associated with liver involvement in…
