Background/Purpose: Elevated levels of RA-associated autoantibodies (ACPA, RF) prior to the clinical onset of inflammatory arthritis (IA) define a state of risk for future development…Abstract Number: 0091 • ACR Convergence 2023
Impaired X-Chromosome Inactivation Maintenance in T Cells Is Associated with Features of Reduced Disease Severity in a Toll-Like Receptor 7-Driven Model of Systemic Autoimmunity
Background/Purpose: Many systemic autoimmune rheumatic diseases, including systemic lupus erythematosus (SLE), Sjögren's syndrome, and systemic sclerosis are highly female-biased. Although these diseases are more prevalent…Abstract Number: 2189 • ACR Convergence 2023
Lymphopenia Fluctuation Patterns Determine the Trajectory of the Disease in Sjogren’s Patients with Hematological Involvement
Background/Purpose: Sjogren's disease (SjD) is characterized by a moderate prevalence of cytopenia, mainly neutropenia and lymphocytopenia with a typical fluctuating pattern. The associations between clinical…Abstract Number: 0093 • ACR Convergence 2023
Single Cell RNA-seq and Mass Cytometry Reveal a Cytotoxic CD8 Effector T Cell Population Associated with Interstitial Lung Disease in Systemic Sclerosis Patients
