Objective: This study aimed to identify the role of IL-18BPa in the regulation of immune responses associated with the pathogenesis of Rheumatoid Arthritis.
Methods: 65 Rheumatoid Arthritis (RA) patients, 22 Osteoarthritis (OA) patients, and 40 sex and age matched healthy donors were enrolled in this study. Synovial fluids mononuclear cells (SFMC) and peripheral blood mononuclear cells (PBMC) were prepared by using Ficoll-Hypaque separation procedure. Super Array analysis was used to measure the expression profile of immune-related genes in RA synovial tissues (RA-ST) and in normal PBMC treated with recombinant human IL-18 binding protein a (IL-18BPa). The mRNA levels of T-helper 1 (TH1) and T-helper 2 (TH2) cytokines were measured by real-time PCR, and the protein levels of IFN-γ, IL-4 and IL-18BPa autoantibodies were detected by ELIS..
