Characterization of T Cell Subsets in the Synovium of Chronic Inflammatory Joint Diseases
Background/Purpose: Rheumatoid arthritis (RA), psoriatic arthritis (PsA), peripheral spondyloarthritis (pSpA), and undifferentiated arthritis (UA) are chronic immune-mediated conditions characterized by joint inflammation. The specific role…Abstract Number: 0588 • ACR Convergence 2022
S-nitrosoglutathione Reductase (GSNOR) Regulates Osteoclast Differentiation
Background/Purpose: S-nitrosoglutathione (GSNO) reductase (GSNOR) is an enzyme which decomposes GSNO and downregulates protein S-nitrosylation. It has been reported that GSNOR KO mice have enhanced…Abstract Number: 1126 • ACR Convergence 2022
Functional NOTCH4 Variants Increase Notch Signaling and Susceptibility for Systemic Sclerosis
Background/Purpose: Genome wide association studies (GWAS) in systemic sclerosis (SSc) have identified several genetic loci, but the search for the causal variant and gene continues.…Abstract Number: 1851 • ACR Convergence 2022
Phenotype and Genotype of Adult-onset Adenosine Deaminase 2 Deficiency Patients
Background/Purpose: Deficiency of adenosine deaminase 2 (DADA2) is an autosomal recessive autoinflammatory disease, characterized by early‑onset vasculopathy, fever, strokes, livedoid rash, hepatosplenomegaly, and hematologic dysfunction,…Abstract Number: 0594 • ACR Convergence 2022
Identification of Peptidylglycine Alpha-Amidating Monooxygenase as a Regulator of Tissue Damage Mediated by Rheumatoid Arthritis Synovial Fibroblasts
Background/Purpose: The minor C allele variant of rs26232 SNP, located within the first intron of the Macrophage Immunometabolism regulator (MACIR) gene, is associated with both…Abstract Number: 1136 • ACR Convergence 2022
Stratification of Systemic Lupus Erythematosus (SLE) Patients Based on the Molecular Patterns of Mouse Models
Background/Purpose: Systemic lupus erythematosus (SLE) is an autoimmune, chronic and multisystemic autoimmune disorder, which typically affects women and presents high severity and mortality. It is…Abstract Number: 1931 • ACR Convergence 2022
NOD2 Mutations Are Associated with Upregulated Type 1 Interferon Gene Expression and Development of Granulomatous Hepatitis in Children with Autoimmune Hepatitis
Background/Purpose: Mutations in the gene NOD2 encoding the nucleotide-binding oligomerization domain-containing protein 2 (NOD2) which controls innate responses to LPS have been linked to Blau…Abstract Number: 0016 • ACR Convergence 2022
Distinct Transcriptomic and Epigenetic Profiles Mediated by Disease Activity in SLE
Background/Purpose: SLE is an autoimmune disease heterogenous for symptoms, disease severity and therapeutic response. This heterogeneity makes stratifying patients difficult. B cells from SLE patients…Abstract Number: 0602 • ACR Convergence 2022
Cellworks Biosimulation Model (CBM) for Rheumatoid Arthritis (RA), Accurately Captures Patient’s Disease Activity at the Molecular Level Using Their Omics Data and Can Bring Personalization to Treatment Selection in RA
Background/Purpose: Patients with RA demonstrate varied individual responses to the many treatment options available. In the absence of accurate, precision prediction of medication response, current…Abstract Number: 1139 • ACR Convergence 2022
Molecular Pathways Identified from Risk Alleles Identify Mechanistic Differences in Systemic Lupus Erythematosus Patients of East Asian and European Ancestry
Background/Purpose: SLE is a multi-organ autoimmune disorder with a prominent genetic component. Individuals of Asian-Ancestry (AsA) disproportionately experience more severe SLE compared to individuals of…Abstract Number: 1990 • ACR Convergence 2022
Artificial Intelligence Applied to Transcriptomics Profiling of Synovial Tissue Biopsies Accurately Predicts Rheumatoid Arthritis Patients Who Will Respond or Be Refractory to Standard Biological Treatments
Background/Purpose: In recent years, biological therapies have revolutionized treatments of Rheumatoid Arthritis (RA). However, about 40% of RA patients do not respond to given biologics…Abstract Number: 0024 • ACR Convergence 2022
Exposure to Pollutants with Endocrine Disrupting Properties Is Associated with Early Cartilage Defects and Chondrocyte Inflammatory and Oxidative Activation
Background/Purpose: Humans are exposed to pollutants with endocrine disruptors (ED) properties from their in utero life. Among them, a mix of 15 pollutants (perfluorinated compounds,…Abstract Number: 0603 • ACR Convergence 2022
Survivin-dependent Regulation of Bivalent Chromatin and Its Relevance for Adaptive Immunity
Background/Purpose: Bivalent chromatin (BvCR) is characterized by simultaneous binding of active and repressive modifications to the histone H3 proteins. Influencing expression of the genes, BvCR…Abstract Number: 1142 • ACR Convergence 2022
The Lupus Risk Allele Associated Xq28 Haplotype Identifies the Molecular Endotype of a Cohort of European SLE Patients with Enhanced IRAK1 Signaling
Background/Purpose: Previous genetic association studies identified a 9 gene region of Xq28 containing IRAK1 as a risk locus for SLE. IRAK1 plays key roles downstream…Abstract Number: 2044 • ACR Convergence 2022
Abnormalities of Extracellular Matrix Modeling Gene Expression in Salivary Gland Epithelial Cells of Patients with Sjögren’s Syndrome
Background/Purpose: Salivary gland epithelial cells (SGECs) are not only the target of autoimmunity in primary Sjögren's syndrome (pSS). SGECs may interact with lymphocytes and therefore…
