5 Must Know Facts For Your Next Test

  1. Rheumatoid arthritis (RA) is an autoimmune disorder where the immune system mistakenly attacks joint tissues.
  2. Cytokines such as TNF-alpha and IL-1 play crucial roles in the inflammation seen in RA.
  3. Autoantibodies like rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPAs) are often present in RA patients.
  4. Certain infections can trigger reactive arthritis, a form of arthritis linked to immune response against pathogens.
  5. The synovial membrane becomes inflamed in RA, leading to pannus formation which damages cartilage and bone.
