Serum Autoantibodies Differentiate Rheumatoid Arthritis Subgroups
Advancing Rheumatoid Arthritis Research: Distinct Autoantibody Signatures in ACPA+ and ACPA- Patients
Patients with rheumatoid arthritis (RA) can be categorized as either anti-citrullinated protein antibody-positive (ACPA+) or negative (ACPA-). In this webinar, Dr. Sung will present his research exploring a broad range of serological autoantibodies to uncover immunological differences between these RA subgroups using data from ACPA+ RA patients, ACPA- RA patients, and matched healthy controls.
Learning objectives
- Learn how 1600+ IgG autoantibodies from serum were screened, yielding biologically relevant and immunologically significant insights.
- Discover the distinct autoantibody profiles identified in ACPA+ and ACPA- patients.
- Understand which proteins and their associated biological processes were predominantly targeted by these autoantibodies.
- Explore the implications of autoantibody biomarkers in RA subgroups and their correlation with the Clinical Disease Activity Index, a measure of disease activity.
- Examine how autoantibody biomarker signatures have the potential to enhance patient stratification and could contribute to diagnostic accuracy in RA.

WebinarFinding the signal: Identifying reproducible biomarkers in high-plex proteomics
In biomarker discovery, the challenge is rarely a lack of data. Rather, it is knowing how to separate meaningful biological signal from technical distraction. This webinar focuses on how to use univariate analysis as a practical and powerful entry point for biomarker discovery in high-plex proteomics studies.
WebinarMore than the sum of its parts: How harmonized proteomic data reveals meaning across disparate clinical cohorts
Proteomics data generated across sites, time points, and workflows can be difficult to compare using standard normalization alone. This webinar shows how harmonization aligns datasets into a shared biological framework and reveals signals across studies and cohorts, highlighted through the GNPC’s analysis of 40,000 patient samples.
