Autoantibodies to Transcription Factor a Mitochondria Link Mitochondrial Damage and Thrombosis in Systemic Lupus Erythematosus
Background/Purpose: Upon activation with interferon (IFN) and RNP-immune complexes, defective mitophagy in neutrophils results in the release of mtDNA in complex with transcription factor A…Abstract Number: 1734 • ACR Convergence 2023
Serum PDGF-BB Levels Correlate with Lung Fibrosis in Mice Injected with Malondialdehyde-Acetaldehyde and/or Citrulline Modified Vimentin
Background/Purpose: Pulmonary manifestations of rheumatoid arthritis (RA), such as interstitial lung disease (RA-ILD), are a major contributor to morbidity and mortality. The mechanism of pulmonary…Abstract Number: 1741 • ACR Convergence 2023
The Occurrence and Phenotype of Autoreactive T Cells in the At-Risk Phase of Rheumatoid Arthritis
Background/Purpose: CD4+ T cells recognizing citrullinated epitopes are present in peripheral blood of anti-citrulline protein antibody (ACPA) positive rheumatoid arthritis (RA) patients at time of…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: 1749 • ACR Convergence 2022
Mass Spectrometry-Based HLA Peptidomics Analysis Reveals Both Expected and Novel Citrullinated Antigen Targets in Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) is an autoimmune disease in which citrullinated self-antigens are recognized by anti-citrullinated protein antibodies (ACPA) and T cells. ACPA are a…Abstract Number: 0045 • ACR Convergence 2022

Background/Purpose: ACPAs are present in two-thirds of patients with rheumatoid arthritis (RA) and are associated with higher risks for severe bone erosions. The pathogenic role…Abstract Number: 2026 • ACR Convergence 2022
Serum and Tear Autoantibodies from nor Mice as Potential Diagnostic Indicators of Local and Systemic Inflammation in Sjögren’s Syndrome
Background/Purpose: Sjögren's Syndrome (SS) is an autoimmune disease characterized by infiltration of lymphocytes into lacrimal (LG) and salivary (SG) glands and their concurrent loss of…Abstract Number: 0048 • ACR Convergence 2022
Combination of Repetitive Inhalant Endotoxin Exposure and Collagen-induced Arthritis Interact in a Testosterone-dependent Manner to Drive Inflammatory Lung Disease Processes and Arthritis Severity in Mice
