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: 1661 • ACR Convergence 2023
Spatial Transcriptional Alterations in the Cellular Landscape of Pediatric Scleroderma Skin
Background/Purpose: Recent single-cell RNA sequencing (scRNA seq) data has been generated across several tissues in autoimmune diseases, helping to understand the cellular and molecular underpinnings…Abstract Number: 1762 • ACR Convergence 2023
Single-cell RNA Sequencing Analysis and Immune Profiling of Antigen-specific T Cells in Patients with Rheumatoid Arthritis and Healthy Controls
Background/Purpose: Single-cell analysis has emerged as a powerful tool for investigating the transcriptomics and T-cell receptor (TCR) diversity in patients with rheumatoid arthritis (RA). However,…Abstract Number: 2342 • ACR Convergence 2023
Modulation of B Cell and Interferon Pathways by Ianalumab in Patients with Systemic Lupus Erythematosus: Findings from a Phase 2 Clinical Trial
Background/Purpose: Ianalumab (VAY736) is an afucosylated monoclonal antibody targeting the B cell activating factor receptor (BAFFR) that depletes B cells via enhanced antibody dependent cellular…Abstract Number: 2540 • ACR Convergence 2023
The Molecular Stratification of Rheumatoid Arthritis Using High-throughput Technologies Is Directly Associated with Disease Activity and Clinical Response
Background/Purpose: Rheumatoid arthritis (RA) is a remarkably heterogeneous autoimmune disease whose clinical outcomes with disease-modifying antirheumatic drugs (DMARDs) remain unpredictable. The aim of this study…Abstract Number: 2586 • ACR Convergence 2023
A Novel Blood-Based Assay Differentiates Seropositive and Seronegative Rheumatoid Arthritis from Healthy Individuals and Those with Other Inflammatory Diseases or Osteoarthritis
Background/Purpose: Non-invasive differentiation of seropositive and seronegative rheumatoid arthritis (RA) from other conditions has been limited in the current practice. We aimed to evaluate the…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: 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…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…
