Identification and functional characterisation of urinary protein biomarkers for rheumatoid arthritis

Key Points

• The research aims to identify and characterize a novel urinary protein biomarker for rheumatoid arthritis.
• Identification of urinary protein biomarkers through analysis of urine samples.
• Assessment of biomarker correlation with rheumatoid arthritis disease activity and clinical outcomes.
• IGLV3-1 is identified as a novel urinary protein biomarker for RA.
• The biomarker reflects disease activity levels and predicts clinical outcomes.
