Abstract Introduction Interleukin IL -23 is essential for the development of various experimental autoimmune models. However the role of IL-23 in non-autoimmune experimental arthritis remains unclear. Here we examined the role of IL-23 in the non-autoimmune antigen-induced arthritis AIA model. In addition the regulatory potential of IL-23 in IL-17A and retinoic acid-related orphan receptor gamma t RORyt expression in CD4 and TCRyS T cells was evaluated systemically as well as at the site of inflammation. Methods Antigen-induced arthritis was induced in wild-type IL-23p19-deficient and IL-17 Receptor A - knockout mice. At different time points synovial cytokine and chemokine expression was measured.
