Comprehensive Autoantibody Profiling Highlights Clinical Relevance of Autoantibodies to G Protein-coupled Receptors in Systemic Sclerosis: Insights from a B-cell Depletion Clinical Trial
Background/Purpose: Systemic sclerosis (SSc) affects the skin and internal organs with a poor prognosis. While the exact cause remains unclear, increasing evidence indicates that B…Abstract Number: 2391 • ACR Convergence 2024
Identification of Patients with ANA Negative and Double Stranded DNA Positive: What Is the Significance in Daily Rheumatology Practise
Background/Purpose: The anti-nuclear antibody (ANA test) is a sensitive screening tool used when assessing patients with possible autoimmune rheumatic diseases (ARD). Homogeneous staining positivity is…Abstract Number: 0011 • ACR Convergence 2024
Preclinical Manufacturability and Activity of KYV-102 from Patients with Systemic Lupus Erythematosus Using Ingenui-T: A Rapid, Autologous Chimeric Antigen Receptor T-Cell Manufacturing Solution Utilizing Whole Blood
Background/Purpose: Apheresis in conventional chimeric antigen receptor (CAR) T-cell therapy can be burdensome, and conventional manufacturing cultures apheresis-derived cells for 7-14 days, leading to a…Abstract Number: 2665 • ACR Convergence 2024
Autoantibody Titers Against Specific Epitope Peptides Predict Treatment Resistance in Interstitial Lung Disease Associated with Anti-MDA5 Dermatomyositis
Background/Purpose: Anti-melanoma differentiation-associated gene 5 (MDA5)-positive dermatomyositis (DM) is frequently associated with rapidly progressive interstitial lung disease (RP-ILD), leading to poor prognosis. Initial combinational therapy…Abstract Number: 0032 • ACR Convergence 2024
Increased Expression of Malondialdehyde-Acetaldehyde and Citrullinated Proteins in Myocardial Tissues During the Early Evolution of Collagen-Induced Arthritis
Background/Purpose: The risk of heart failure (HF) is increased in patients with rheumatoid arthritis (RA), although mechanisms of myocardial dysfunction underlying HF development in RA…Abstract Number: 2667 • ACR Convergence 2024
Anti-Mi2 Autoantibodies in Dermatomyositis Patients Also Recognize Autoimmune Regulator (AIRE) Protein
Background/Purpose: Many myositis patients have myositis-specific autoantibodies (MSA) that define unique clinical phenotypes. For instance, dermatomyositis (DM) patients with anti-Mi2 autoantibodies have weaker muscles, higher…Abstract Number: 0033 • ACR Convergence 2024
Refined Autoantibody Profiles in RA Reveal That Primarily ACPAs Binding Non-glycine Citrulline Motifs Are Associated with Shared Epitope Alleles
Background/Purpose: Carriage of HLA-DRB1 shared epitope (SE) alleles and a history of smoking, have been identified as the most prominent risk factors for development of…Abstract Number: 0039 • ACR Convergence 2024
Blockade of Soluble and Cell Surface PAD Activity Prevents the Generation of Citrullinated Autoantigens Recognized by RA Patients’ Serum
Background/Purpose: Anti-citrullinated protein autoantibodies (ACPA) promote inflammation and joint tissue injury and define a poor prognostic group of patients with rheumatoid arthritis (RA). Citrullinated autoantigens…Abstract Number: 0320 • ACR Convergence 2024
Comparative Transcriptional Profiling Reveals Shared Pathway Activation Between Human Jo-1+ Anti-Synthetase Syndrome and Murine Histidyl-tRNA Synthetase-Induced Myositis
Background/Purpose: Previous work has shown unique gene expression profiles in muscle tissue corresponding to the anti-synthetase syndrome, with an emphasis on interferon gene signatures (Type…Abstract Number: 0837 • ACR Convergence 2024
Bispecific Autoantigen-T Cell Engagers (BaiTE) to Selectively Target Autoreactive B Cells in Antiphospholipid Syndrome
Background/Purpose: Available drugs to treat autoimmune diseases are indiscriminate, suppressing self-reactive and protective immune responses alike. This lack of therapeutic precision results in infection and…
