RNA-Binding Proteins That Are Highly Expressed and Enriched in Healthy Cartilage but Suppressed in Osteoarthritis
Background/Purpose: RNA-binding proteins (RBPs) have diverse and essential biological functions, but their role in cartilage health and disease is largely unknown. The objectives of this…Abstract Number: 1595 • ACR Convergence 2023
Pharmacological Modulation of Krüppel-like Factor 4 Reduces the Severity of Experimental Osteoarthritis via Tissue Protection and Regeneration
Background/Purpose: Krüppel-like factors (KLFs) are members of the zinc finger family of transcription factors, which includes 17 members in mammals. We found that expression of…Abstract Number: 1644 • ACR Convergence 2023
The EISER Study: Identifying Microbial Factors Associated with Subclinical Gut Inflammation in Spondyloarthritis Patients
Background/Purpose: Nearly 8% of patients with spondyloarthritis (SpA) manifest symptoms that are compatible with active inflammatory bowel disease (IBD), despite not having any previous diagnosis…Abstract Number: 1657 • ACR Convergence 2023
Mapping the Network of Coordinated Immune Dysregulation in Juvenile Dermatomyositis at Single-cell Resolution
Background/Purpose: Juvenile Dermatomyositis (JDM) is a rare multisystem autoimmune condition that involves complex immune responses in both innate and adaptive compartments. Currently, we have a…Abstract Number: 004 • 2023 Pediatric Rheumatology Symposium
Analysis of Patients with Juvenile Dermatomyositis Compared to Healthy Controls Using CITE-seq Identifies Differences in Cell Composition and Gene and Epitope Expression
Background/Purpose: Juvenile dermatomyositis (JDM) is a rare and serious systemic autoimmune condition, and much remains unknown about the pathogenesis, the immune cell types and cell-specific…Abstract Number: 0563 • ACR Convergence 2022
High-Dimensional Immunophenotyping with Mass Cytometry Reveals Unique Immune Cell Aberrations in Patients with Undiagnosed Inflammatory and Autoimmune Diseases
Background/Purpose: Few tools are available to evaluate the immune dysregulation in patients with severe autoimmune or inflammatory conditions that do not conform to well-defined rheumatologic…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: 0632 • ACR Convergence 2022
Single-cell Multiomic Profiling Differentiates Ancestral B Cell Pathologies Contributing to Lupus Disease Activity
Background/Purpose: Genetic ancestry impacts SLE prevalence, clinical presentation, and treatment response; however, the molecular underpinnings of this disparity remain poorly understood. Recent findings demonstrate that…Abstract Number: 1087 • ACR Convergence 2022
Identification of Novel Proteomic Biomarkers of Disease Activity in ANCA-Associated Vasculitis Using a High Throughput Approach
Background/Purpose: ANCA-associated vasculitis (AAV) is associated with excess morbidity and mortality. Identifying novel biomarkers may reveal new therapeutic targets and clinically useful biomarkers of disease…Abstract Number: 1124 • ACR Convergence 2022
CD4+ Cytotoxic T Lymphocytes (CTL) Are Present in Sjögren’s Disease Minor Salivary Glands and Associate with Markers of Epithelial Cell Damage near Infiltrates
Background/Purpose: CD4+ T cells dominate focal lymphocytic infiltrates in Sjögren's disease (SjD), but their differentiation states have remained unclear. Here, we used single cell (sc)RNAseq…Abstract Number: 1125 • ACR Convergence 2022
Genomics of JAK-STAT Signaling in Venous Thromboembolism
Background/Purpose: Janus kinase inhibitors (JAKi) have been associated with an increased risk of venous thromboembolism (VTE). This concern limits the use of JAKi-based therapy. Hence,…Abstract Number: 1145 • ACR Convergence 2022
The Prostate Plays a Role in Serum Urate Levels and the Risk of Gout in Men
Background/Purpose: Men have higher serum urate (SU) and increased prevalence of gout compared to pre-menopausal women. Xanthine oxidoreductase (XOR), encoded by the XDH gene, is…Abstract Number: 1585 • ACR Convergence 2022
Decreased Discontinuation and Switching of B/tsDMARD Therapy in RA Patients When Treatment Is Aligned with a Molecular Signature Response Classifier: An Analysis from the Study to Accelerate Information of Molecular Signatures (AIMS)
Background/Purpose: Rheumatoid arthritis (RA) patients with inadequate response to methotrexate often experience trial-and-error treatment selection due to a lack of guidance from clinical guidelines or…Abstract Number: 1625 • ACR Convergence 2022
Single Cell and Spatial Transcriptomics Identifies Pathogenic Drivers of Sjogren’s Disease in Humans
Background/Purpose: Sjogren's Disease(SjD) is a systemic autoimmune disease characterized by exocrine dysfunction. The pathogenesis is incompletely understood, but involves gene-environment interactions leading to infiltration of…Abstract Number: 0040 • ACR Convergence 2022
Plasma Proteomic Signatures in Juvenile Dermatomyositis Highlight Novel Proteins and a Protein Module That Associate with Skin and Global Disease Activity
Background/Purpose: Juvenile dermatomyositis (JDM) patients display heterogenous disease phenotypes and treatment response patterns. Our study used a multiplexed proteomics assay for measurement of 3072 proteins…
