Tryptophan and kynurenine concentration in cultures of IDO-expressing DCs. Native DCs (control), DCs infected with IDO-adeno-GFP, IDO-adeno, or native replication-defective adenoviruses (control) were cultured in RPMI 1640 plus 10% FCS. Tryptophan (A) and kynurenine (B) concentrations were determined and the values (μM/105 cells) are shown on the ordinate.
