Abundance of Plasma Microbial Small RNAs Are Predictive of Improvement in Disease Activity after DMARD Initiation for Rheumatoid Arthritis
Background/Purpose: Small RNAs (sRNAs) are important regulators of biological processes and are potential biomarkers of disease and drug response. We previously found that microbial sRNAs…Abstract Number: 1967 • 2018 ACR/ARHP Annual Meeting
Detection of Association of Long Noncoding RNA ATP6V0E2-AS1 Single Nucleotide Polymorphism with Susceptibility to Myeloperoxidase-ANCA Associated Vasculitis Based on Transcriptome Analysis
Background/Purpose: Because of the low prevalence, only three genome-wide association studies, all from the Caucasian populations, have been reported on ANCA-associated vasculitis (AAV) thus far;…Abstract Number: 2018 • 2018 ACR/ARHP Annual Meeting
Microenvironment Driven Re-Shaping of Pathogenic T Effector and Regulatory Subset in Active Juvenile Idiopathic Arthritic Patients
Background/Purpose: We have previously identified two CD4 pathogenic circulatory subsets in both T effector (CPLs) and T regulatory (iaTreg) compartments that are both HLA-DR+, antigen…Abstract Number: 2055 • 2018 ACR/ARHP Annual Meeting
Laser Capture Microdissection to Interrogate B Cells in RA Synovial Tissue
Background/Purpose: Rheumatoid arthritis is an autoimmune disease characterized by immune cell infiltration in synovial tissue and progressive bone damage. B cells are abundant in the…Abstract Number: 2324 • 2017 ACR/ARHP Annual Meeting
Single Cell RNA-Sequencing of Bone Marrow Macrophages Identifies a Distinct Subpopulation in Systemic JIA with Features of Interferon Response, Endocytic Vesicles and Phagocytosis
Background/Purpose: Macrophage activation syndrome (MAS) is a life-threatening complication of systemic juvenile idiopathic arthritis (SJIA), characterized by activation and expansion of cytolytic lymphocytes and macrophages…Abstract Number: 2432 • 2017 ACR/ARHP Annual Meeting
Longitudinal Changes in Gene Expression Associated with Disease Activity during Pregnancy and Post-Partum Among Women with Rheumatoid Arthritis

The Role of Interferon in Autoimmune-Susceptible Ro60 Knockout Mice
Background/Purpose: The Ro60 protein is a prominent autoantigen in systemic lupus erythematosus (SLE) and Sjogren’s syndrome (SS). Anti-Ro antibodies are strongly associated with UV-mediated skin…Abstract Number: 2757 • 2017 ACR/ARHP Annual Meeting
Kidney and Skin Single-Cell RNA Sequencing in Lupus Nephritis Provides Mechanistic Insights and Novel Potential Biomarkers
Background/Purpose: Classification and treatment decisions in lupus nephritis (LN) are largely based on renal histology. Single-cell RNAseq (scRNAseq) analysis may accurately differentiate types of renal…Abstract Number: 181 • 2017 ACR/ARHP Annual Meeting
Identification of Disease-Susceptible Lncrna Contributed to Abnormal Activation of Type I Interferon Pathway in Systemic Lupus Erythematosus
Background/Purpose: Dysregulation or dysfunction of some key moleculars in signaling pathway is involved in disease pathogenesis. Long non-coding RNA (lncRNA), as a regulator of gene…Abstract Number: 302 • 2017 ACR/ARHP Annual Meeting
From Monocytes to Macrophages: the Pathogeneses of Spontaneous Inflammatory Arthritis in CD11c-Flip-KO (HUPO) Mice
Background/Purpose: We have generated a CD11c-Flip-KO mouse line (HUPO) that spontaneously develops erosive arthritis with incidence 70-80% at age ≥ 20 weeks. This study aimed…Abstract Number: 387 • 2017 ACR/ARHP Annual Meeting
F4/80hi Synovial Macrophages in the Pathogeneses of Spontaneous Inflammatory Arthritis in CD11c-Flip-KO (HUPO) Mice
Background/Purpose: Synovial tissue macrophages (STMs) are critical in the pathogenesis of rheumatoid arthritis (RA). During homeostasis, the majority of murine synovial tissue resident macrophages (TRMs)…Abstract Number: 770 • 2017 ACR/ARHP Annual Meeting
Integrating Analysis of Skin RNA in Situ Hybridization Using Rnascope and Whole Skin Gene Expression in Systemic Sclerosis Skin to Localize Key Pathogenic Drivers of Skin Fibrosis
Background/Purpose: Skin gene expression profiling can distinguish SSc from normal skin and can detect different subsets of disease. Previous studies have reported a cross-sectional relationship…Abstract Number: 1026 • 2017 ACR/ARHP Annual Meeting
Gene Expression Analysis Reveals Common Pathways of Tissue Pathogenesis in Lupus Organ Involvement
Background/Purpose: Lupus is a prototypic autoimmune disease characterized by B cell hyperactivity, autoantibody formation and resultant tissue damage. The mechanisms underlying tissue pathology in lupus…Abstract Number: 1330 • 2017 ACR/ARHP Annual Meeting
Rhesus Theta Defensin 1 (RTD-1) Suppresses Disease-Associated Genes and Induces Anti-Inflammatory Expression Signature in Synovial Tissues of Rat Model of Rheumatoid Arthritis
Background/Purpose: Theta (θ) defensins are the only known macrocyclic peptides found in the Animal kingdom and are exclusively expressed in Old World monkeys. θ-defensins were…Abstract Number: 1721 • 2017 ACR/ARHP Annual Meeting
Long Noncoding RNA H19X Is a Key Regulator of Apoptosis and Proliferation of Fibroblasts in Systemic Sclerosis and Other TGFβ-Driven Fibrotic Diseases
