Expression of IL-1β Receptor Antagonist in Patients with Severe Osteoarthritis of the Knee–The Mechanism Limiting the Inflammation in Osteoarthritis

Abstract: Introduction: Expression of interleukin-1β (IL-1β) in the synovial fluid of patients with osteoarthritis has been confirmed. The overall effect of this cytokine can be described as a chondrocyte-dependent cartilage destructive potential. The interleukin-1β receptor antagonist (IL-1Ra) blocks the interaction between IL-1β and its receptor on the cell surface. Human chondrocytes and synoviocytes produce IL-1Ra in a response to stimulation by IL-1β and IL-6. The local production of IL-1Ra in the joint has a prote… Show more

“…IL-1β-mediated catabolism is considered as the key pathophysiological process in the course of OA [ 15 ]. An important mechanism in the OA pathogenesis is IL-1β-induced upregulation of matrix metalloproteinases (MMPs), the group of enzymes involved in the degradation of collagen and other proteins in the ECM.…”
