Effect of PHA stimulation in PBMCs. Indoleamine 2,3-dioxygenase activity, expressed as the kynurenine to tryptophan ratio (Kyn/Trp in μmol/mmol, note log scale) (A) and concentrations of kynurenine (B) and tryptophan (C) in unstimulated (white bars) and PHA-stimulated (black bars) PBMC. Results shown are the mean values ± SEM of four independent experiments run in duplicates (*P < 0.05, compared to unstimulated cells).
