Figure 2

IFNγ induced indoleamine 2,3-dioxygenase activity in CNE2 cells in a dose- and time-dependent manner. (A) After CNE2 cells were cultured in the presence of different concentrations of IFNγ for 24 h, the supernatants of CNE2 cells were analyzed for Kyn production using high performance liquid chromatography (HPLC). (B) CNE2 cells were cultured with 50 U/ml IFNγ for different incubation times and the supernatants were analyzed for Kyn production by HPLC. □: untreated groups; ■: treated groups. Each value is the mean ± SD of three determinations.
