With ample experience in the research of autoimmune diseases, Creative Biolabs provides antibody development and cell-based therapy development services for autoimmune diseases such as rheumatoid arthritis (RA) to customers around the world.

Introduction to Rheumatoid Arthritis (RA)

RA is a complex inflammatory autoimmune disease. It is characterized by chronic inflammation in the synovial membrane of affected joints. Firstly, it affects small joints, then larger joints, eventually the skin, eyes, heart, kidneys, and lungs. All this damage to the joints causes deformities and bone erosion. Patients are very painful.

Treatment of RA

  • B cells can suppress autoimmunity in different animal models either through the production of interleukin 10 (IL-10) or transforming growth factor-β (TGFβ) as well as by cytokine independent functions. A study has demonstrated that a transitional-marginal zone precursor B cell subset is protective against murine inflammatory arthritis via the production of IL-10. In another study, B cells in the joints of patients with RA may directly participate in receptor activator of nuclear factor κB ligand (RANKL) synthesis and indirectly modulate the RANKL/osteoprotegerin (OPG) system through the production of proinflammatory cytokines, such as tumor necrosis factor (TNF) and interleukin 17A (IL-17A).

  • Non-steroidal anti-inflammatory drugs (NSAIDs) work by inhibiting cyclo-oxygenase to prevent the synthesis of prostaglandins, prostacyclin, and thromboxanes. Aspirin is an effective anti-inflammatory for RA when used at high doses, due to the inhibition of prostaglandins. It is one of the oldest NSAIDs used for joint pain. Side effects of aspirin at high doses include tinnitus, hearing loss, and gastric intolerance.
  • Corticosteroids are a more potent anti-inflammatory medication than NSAIDs. They work by preventing the release of phospholipids and decreasing the actions of eosinophils, thereby decreasing inflammation. Their side effects include bone-thinning, weight gain, diabetes, and immunosuppression.
