Summary
Researchers identified a unique autoantibody signature in patients with multiple sclerosis (MS) years before symptom onset. This signature may serve as an early diagnostic biomarker for MS and related neuroinflammatory syndromes.
Area of Science:
- Neuroimmunology
- Autoimmunity
- Biomarker Discovery
Background:
- B cells play a role in multiple sclerosis (MS) pathophysiology, but a predictive or diagnostic autoantibody has not been identified.
- The Department of Defense Serum Repository (DoDSR) provides a large cohort for pre-symptomatic analysis.
Conclusions:
- An autoantibody signature can identify a subset of PwMS years before clinical diagnosis, suggesting an immunologically active prodromal phase.
- This signature may be a valuable antigen-specific biomarker for early detection and risk stratification in patients with neuroinflammatory syndromes.
