Figure 1. IL-4 increases IFN-γ -induced IDO mRNA expression.

Figure 1

(A) EOC13.31 microglia cells were treated with 10 ng/ml IFN-γ for the indicated time periods, and total RNA was analyzed for IDO expression by real time RT-PCR. (B) EOC13.31 microglia cells were treated with the indicated concentrations of IFN-γ and IL-4 for 24 hours, and total RNA was analyzed for IDO expression by real time RT-PCR. (C) EOC13.31 microglia cells were treated with 10 ng/ml of IFN-γ with and without 25 ng/ml of IL-4 for 24 h, in the presence of the indicated concentration of anti-IL-4 antisera. Total RNA was analyzed for IDO expression by real time RT-PCR.
