IFN-γ induces IL-18Rα mRNA expression in RA-FLS. (a) Results represent the mean ± SEM of relative IL-18Rα expression (based on the expression of β-actin housekeeping gene) in six RA-FLS cultures after 25, 30, and 35 PCR cycles. (b) IL-18Rα RT-PCR products of two representative cultures after 25, 30, and 35 cycles, and the corresponding β-actin RT-PCR products (bottom lane). FLS = fibroblast-like synoviocytes; IL-18Rα = IL-18 receptor α; RA = rheumatoid arthritis; RT-PCR= reverse transcriptase polymerase chain reaction.
