Rheumatoid arthritis (RA) is an autoimmune disorder characterized by joint swelling, pain, and damage from chronic inflammation. RA occurs in roughly 5 per 1,000 people and may cause severe and irreversible joint damage and debilitation1. The key to combating RA is early diagnosis and treatment with various anti-inflammatory agents collectively known as disease-modifying antirheumatic drugs (DMARDs), which can prevent or slow joint damage in 90% of patients. Unfortunately, no cure for the disease exists, meaning that lengthy and potentially costly treatment regimens are often necessary. As such, RA research is very important for identifying more effective therapeutic agents.
