Open wide: biomarkers from a cheek swab may predict rheumatoid arthritis susceptibility

Researchers from Washington State University and Arthritis Northwest (both WA, USA) report on biomarkers obtained from cells obtained from cheek swabs that may aid in the diagnosis and early treatment of rheumatoid arthritis. Rheumatoid arthritis is a chronic condition that manifests as pain and swelling in the joints. In the United States alone, the condition affects up to 200,000 people annually. Current therapeutics and treatments demonstrate limited effectiveness in those who have already developed the disease. However, detecting, diagnosing and treating the condition early enough may cause remission of symptoms. Proven biomarkers would allow early treatment before even the first symptoms appear.  The study...
