Expression of the cGAMP Transporter SLC19A1 Is Altered in Systemic Lupus Erythematosus
Background/Purpose: Inappropriate sensing of nucleic acids leading to enhanced type I interferon (IFN) induction is a hallmark of SLE, contributing to breakdown of immune tolerance…Abstract Number: 0292 • ACR Convergence 2020
Exhausted pSTAT5-IFNα Signaling Pathways in SLE Patients Are Correlated with Age-associated B Cells and Disease Activity
Background/Purpose: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by periods of elevated and suppressed clinical symptoms. Specific cell subsets, such as CD11c+ age-associated…Abstract Number: 0304 • ACR Convergence 2020
Type I Interferon Inhibits Glucocorticoid-Induced Leucine Zipper (GILZ) Expression and Upregulation by Glucocorticoids
Background/Purpose: Glucocorticoids (GC) are broadly used in the treatment of inflammatory diseases, including systemic lupus erythematosus (SLE). Despite their widespread use, most SLE patients do…Abstract Number: 0461 • ACR Convergence 2020
High-Throughput Single-Cell Analysis Reveals Unique Lung Cellular Subsets in a Murine Model of Rheumatoid Arthritis-Inflammatory Lung Disease
Background/Purpose: Rheumatoid arthritis (RA)-associated inflammatory lung disease is an extra-articular manifestation of RA associated with increased morbidity and mortality, whose precise molecular mechanisms remain undetermined.…Abstract Number: 0861 • ACR Convergence 2020
Hydroxychloroquine Use Is Associated with Diminished Type I Interferon-related Pathways in Systemic Lupus Erythematosus Patients
Background/Purpose: Hydroxychloroquine (HCQ) has been used for decades to treat systemic lupus erythematosus (SLE) and is associated with decreased lupus flares and damage. However, despite…Abstract Number: 1402 • ACR Convergence 2020
Galectin-3 Decreases the Activity of 4-1BB by Facilitating Its Decoy Surface Binding in Rheumatoid Arthritis
Background/Purpose: Orchestration of immune checkpoints is central for the outcome of immune activation, especially in patients with rheumatoid arthritis (RA). We have previously shown that…Abstract Number: 1526 • ACR Convergence 2020
Single Cell Analysis of Skin and Blood of Scleroderma Patients Towards Identification of New Disease Mechanisms, Prognostic Biomarkers and Potential Therapeutic Targets
Background/Purpose: Systemic sclerosis (SSc) is characterized by fibrosis, microangiopathy and immune dysregulation. Despite many years of research, the pathogenesis of SSc is poorly understood; there…Abstract Number: 1952 • ACR Convergence 2020
Activated Memory T Cells Produce Ligands That Cause NF-κB-dependent Inflammatory Activation of the Endothelium: Identification of Novel Therapeutic Targets
Background/Purpose: Endothelial cells (EC) are important contributors to inflammation via expression of inflammatory mediators, including cytokines, chemokines and adhesion molecules. Production of these inflammatory mediators…
