Broad Immunophenotyping Results: CCR10 Expressing CD8 T Cells Distinguish Psoriatic Arthritis from Psoriasis Limited to Skin Involvement
Background/Purpose: Studies that compare the immune cell phenotype or function from patients with psoriatic arthritis (PsA) to patients with psoriasis limited to cutaneous involvement (Pso)…Abstract Number: 1913 • 2017 ACR/ARHP Annual Meeting
Inter-Omic Analysis Reveals Functional Relationship between Diverse Gut Microbiota and Dysregulated Host Immune Response in HLA-B27-Mediated Experimental Spondyloarthritis
Background/Purpose: HLA-B27 has been hypothesized to alter gut microbiota and host-microbe interactions to promote spondyloarthritis (SpA). In HLA-B27 transgenic (HLA-B27 Tg) rats with experimental SpA,…Abstract Number: 1914 • 2017 ACR/ARHP Annual Meeting
Discovery of a Novel CD8+ T Cell Population in Ankylosing Spondylitis Implicates Gut-Joint Trafficking in the Disease
Background/Purpose: Ankylosing spondylitis (AS) has a strong connection with gut inflammation: 10% of AS patients have inflammatory bowel disease (IBD) and 60% have subclinical ileal…Abstract Number: 1915 • 2017 ACR/ARHP Annual Meeting
Gut-Derived TNF As Risk Factor for the Development of Sacroiliac Inflammation
Background/Purpose: An intruiging link exists between gut and joint inflammation in spondyloarthritis (SpA). About 50% of patients has subclinical (eg. microscopic) gut inflammation, which represents…Abstract Number: 1916 • 2017 ACR/ARHP Annual Meeting
The Interferon Gamma Release Assay Is a Novel Predictor of Disease Activity in Systemic Lupus Erythematosus
Background/Purpose: Interferon gamma (IFN-G) is critical cytokine for defense against intracellular pathogens; it is also involved in the pathogenesis of systemic lupus erythematosus (SLE). The…Abstract Number: 1917 • 2017 ACR/ARHP Annual Meeting
A Novel Type I Interferon Biomarker on B Cell Predicts with Disease Activity in SLE and Can be Measured By Cell Surface Tetherin (CD317)
Background/Purpose: SLE is an IFN-I-mediated disease with dysregulated handling of self-nuclear antigens triggering anti-viral immune mechanisms. The level of IFN-I activity appears to stratify for…Abstract Number: 1918 • 2017 ACR/ARHP Annual Meeting
Blood Levels of Complement Split Product iC3b and C3 Outperform Traditional Biochemical Measures of SLE Disease Activity in Associating with Active and Clinically Meaningful Changes
Background/Purpose: A major unmet need in SLE is the identification of a biomarker that consistently tracks with disease activity. One current approach is measuring complement…Abstract Number: 1919 • 2017 ACR/ARHP Annual Meeting
The SLE-Key Test Detects an SLE Serologic Signature That Persists over Time and Is Independent of Disease Activity
Background/Purpose: We have developed the iCHIP1,2 to profile repertoires of serum autoantibodies. The first iCHIP application was the SLE-key RuleOut test3,4 , to rule out…Abstract Number: 1920 • 2017 ACR/ARHP Annual Meeting
Tacrolimus Induces Remission in Refractory and Relapsing Lupus Nephritis By Decreasing P-Glycoprotein Expression and Function on Peripheral Blood Lymphocytes
Background/Purpose: About 15-30% of Lupus Nephritis (LN) patients do not respond to first-line immunosuppressive therapy. P-glycoprotein (P-gp) mediated efflux of corticosteroids (CS) may contribute to…Abstract Number: 1921 • 2017 ACR/ARHP Annual Meeting
Urine Angiostatin and VCAM-1 Surpass Conventional Metrics in Predicting Elevated Renal Pathology Activity Indices in Lupus Nephritis
Background/Purpose: The goal of this study is to investigate how urinary angiostatin, VCAM-1 and established measures of renal function relate to specific histologic findings in…Abstract Number: 1922 • 2017 ACR/ARHP Annual Meeting
Cell Type Specific Gene Expression Analysis of Early Systemic Sclerosis Skin Shows a Prominent Activation Pattern of Innate and Adaptive Immune System in the Prospective Registry for Early Systemic Sclerosis (PRESS) Cohort
Background/Purpose: To examine the global gene expression profile in patients with very early diffuse systemic sclerosis (SSc). Methods: Skin biopsies were obtained from patients enrolled…Abstract Number: 1923 • 2017 ACR/ARHP Annual Meeting
Single Cell RNA Sequencing Reveals a Signature of Endothelial Injury in Scleroderma Skin
Background/Purpose: Vascular injury is a hallmark event in the pathogenesis of Systemic Sclerosis (SSc). Endothelial dysfunction happens early in the course of the disease and…Abstract Number: 1924 • 2017 ACR/ARHP Annual Meeting
The Nuclear Receptor ROR-Alpha As a Key Checkpoint of Tissue Repair
Background/Purpose: The Retinoic-acid related Orphan Receptor-alpha (RORα) is a member of the nuclear receptor superfamily and a ligand-dependent transcription factor implicated in a wide range…Abstract Number: 1925 • 2017 ACR/ARHP Annual Meeting
TGFβ Promotes Fibrosis By MYST1-Dependent Epigenetic Regulation of Autophagy
Background/Purpose: Autophagy (Atg) is catabolic process allowing cells to degrade unnecessary or dysfunctional cellular organelles. Aberrant activation of Atg has been implicated into the pathogenesis…Abstract Number: 1926 • 2017 ACR/ARHP Annual Meeting
Cardiac Remodeling in Systemic Sclerosis: TGF-β/Fra2-Dependent Autophagy As a Novel Target for Heart Fibrosis
Background/Purpose: SSc patients frequently suffer from primary cardiac involvement. The main histological feature is fibrosis, but the mechanisms responsible for the heart failure remain unclear.…
