Figure 3. Dichotomy of IL4I1 activity induction by IFNγ and IL4.

Figure 3

(A) 105 monocytes, monocyte-derived Mϕ, monocyte-derived DC and B cells were stimulated with IFNγ or IL4 and IL4I1 enzymatic activity against phenylalanine measured after 48h. The mean of 3 experiments ± SD is shown. (B) Kinetics of IL4I1 enzymatic activity of IFNγ-treated Mϕ and DC (left and center) and IL4-treated B lymphocytes (right). Representative experiments are shown. Enzymatic activity is expressed as pmoles H2O2 produced by 105 cells per hour using phenylalanine as substrate. * p < 0.05; ** p < 0.01.
