ZEB2 Acts as a Crucial Transcriptional Regulator Governing Age-Associated B Cell Formation and Pathogenicity in Systemic Lupus Erythematosus
Background/Purpose: Age-associated B cells (ABCs) accumulate and contribute to the pathogenesis of systemic autoimmune diseases like lupus. Despite recent insights into the ontogeny and function…Abstract Number: 0793 • ACR Convergence 2023
The Dual Specificity Phosphatase 6 (DUSP6) Regulates Arthritis Severity and IL10 Production
Background/Purpose: We have previously identified the Huntingtin-interacting protein-1 (HIP1) as a new gene implicated in the regulation of the rheumatoid arthritis (RA) fibroblast-like synoviocyte (FLS)…Abstract Number: 0804 • ACR Convergence 2023
Mutated NOD2 Controls IL-2 Production in Blau Syndrome Patients and Mice
Background/Purpose: Microbial sensing molecule nucleotide-binding oligomerization-domain containing protein 2 (NOD2) is expressed by CD4+ T cells and plays a novel T cell-intrinsic role within CD4+…Abstract Number: 0964 • ACR Convergence 2023
Systemic Sclerosis (SSc) Dermal Fibroblasts Show Shortened Primary Cilia Due to Aberrant Aurora a Kinase Activation Independently of Transforming Growth Factor β Signalling
Background/Purpose: Systemic Sclerosis (SSc) is an autoimmune disorder characterised by abnormal activation of tissue fibroblasts, resulting in tissue and vascular fibrosis of the skin and…Abstract Number: 0508 • ACR Convergence 2022
Detecting the Critical Factors in the Pathogenesis of Anti-melanoma Differentiation-associated Gene 5–positive Dermatomyositis (MDA5 DM) by Gene Expression Analysis of Peripheral Blood
Background/Purpose: MDA5 DM is a distinct subtype of DM that is characterized by high mortality due to rapid progressive interstitial lung disease (ILD). MDA5 is…Abstract Number: 0559 • ACR Convergence 2022
JAK Inhibitor Withdrawal Causes a Transient Proinflammatory Signaling Cascade in Minor Salivary Gland Mesenchymal Stromal Cells
Background/Purpose: Sjögren's Disease (SjD) has high glandular IFNg levels, associated with disease activity and lymphoma risk. We previously showed IFNg-stimulated minor salivary gland (SG)-mesenchymal stromal…Abstract Number: 0615 • ACR Convergence 2022
Semaphorin 5A Suppresses Ferroptosis Through Activation of PI3K-AKT-mTOR Signaling in Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) is a systemic autoimmune disease with synovial inflammation as the main pathological feature, and can eventually lead to irreversible joint or…Abstract Number: 0642 • ACR Convergence 2022
SLAMF6-SAP Signaling Unit Is Increased in SLE T Follicular Helper Cells
Background/Purpose: SLE is a multiorgan disease in which immune cells lack self-tolerance resulting in autoimmunity. SLE T cells infiltrate organs, provide help to autoreactive B…Abstract Number: 1147 • ACR Convergence 2022
Transcriptomic Changes Induced by Tocilizumab in Ex-Vivo PBMCs from Patients with GCA in Remission. Predictors of Response
Background/Purpose: Glucocorticoids (GCs) are only effective therapy able to induce disease remission, but most patients relapse when GC are tapered and suffer from GC-related toxicity.…Abstract Number: 1664 • ACR Convergence 2022
TRIM21 as a Regulator of UVB-Driven IFN Responses in Lupus
Background/Purpose: Patients with systemic lupus erythematosus (SLE) experience photosensitivity where exposure to ultraviolet light B (UVB) drives lupus flares and systemic symptoms. Although the mechanisms…Abstract Number: 2184 • ACR Convergence 2022
CaMK4 Controls the Humoral Response via the T Follicular Helper Compartment and Regulates Autoimmunity
Background/Purpose: Systemic lupus erythematosus (SLE) is characterized by a dysregulated T cell compartment and production of autoantibodies leading to organ damage. We previously identified that…
