  • Title: The IL-12/IL-23 axis and its role in Th17 cell development, pathology and plasticity in arthritis.
    Author: Cornelissen F, van Hamburg JP, Lubberts E.
    Journal: Curr Opin Investig Drugs; 2009 May; 10(5):452-62. PubMed ID: 19431078.
    Abstract:
    Rheumatoid arthritis (RA) was originally thought to be a T-helper (Th)1-, not a Th2-, associated disorder; however, it currently is unclear whether RA is a Th1- and/or Th17-mediated disease, and what the contributions of these T-cell subsets are in the pathogenesis of RA. Results from studies using different arthritis models have demonstrated that IL-17-producing T-cells are the dominant cell type in the development of arthritis. In addition, a critical role of the IL-23/IL-17 axis in the progression to chronic destructive arthritis has been demonstrated. Interestingly, Th1 and Th17 cells both may have unique pathogenic potential, and the recent insights into T-cell plasticity may change the understanding of the role of T-cell subsets in chronic autoimmune diseases.
