dc.description.abstract1 | Introduction: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by neutrophil articular
infiltration, joint pain and the progressive destruction of cartilage and bone. IL-22 is a key effector molecule that
plays a critical role in autoimmune diseases. However, the function of IL-22 in the pathogenesis of RA remains
controversial. In this study, we investigated the role of IL-22 in the early phase of antigen-induced arthritis (AIA) in mice.
Methods: AIA was induced in C57BL/6, IL-22−/−
, ASC−/− and IL-1R1−/− immunized mice challenged intra-articularly with
methylated bovine serum albumin (mBSA). Expression of IL-22 in synovial membranes was determined by RT-PCR.
Articular hypernociception was evaluated using an electronic von Frey. Neutrophil recruitment and histopathological
analyses were assessed in inflamed knee joint. Joint levels of inflammatory mediators and mBSA-specific IgG
concentration in the serum were measured by ELISA.
Results: The IL-22 mRNA expression and protein levels in synovial tissue were increased during the onset of AIA.
In addition, pharmacological inhibition (anti-IL-22 antibody) and genetic deficiency (IL-22−/− mice) reduced
articular pain and neutrophil migration in arthritic mice. Consistent with these findings, recombinant IL-22 joint
administration promoted articular inflammation per se in WT mice, restoring joint nociception and neutrophil
infiltration in IL-22−/− mice. Moreover, IL-22-deficient mice showed reduced synovitis (inflammatory cell influx)
and lower joint IL-1β levels, whereas the production of IL-17, MCP-1/CCL2, and KC/CXCL1 and the humoral
immune response were similar, compared with WT mice. Corroborating these results, the exogenous administration of
IL-22 into the joints induced IL-1β production in WT mice and reestablished IL-1β production in IL-22−/− mice
challenged with mBSA. Additionally, IL-1R1−/− mice showed attenuated inflammatory features induced by mBSA
or IL-22 challenge. Articular nociception and neutrophil migration induced by IL-22 were also reduced in ASC−/− mice.
Conclusions: These results suggest that IL-22 plays a pro-inflammatory/pathogenic role in the onset of AIA through an
ASC-dependent stimulation of IL-1β production. | pt_BR |
