T (100 mg/ml)/A (10 μm)-induced IL-22 mRNA expression under the influence of AhR ligands

mRNA expression after a 4-h incubation period was determined by real time PCR. Data are expressed as mean ± S.D. (n = 4).

Stimulation	IL-22 mRNA
	Fold-induction compared to unstimulated control
T/A	219.7 ± 36.0a
T/A plus β-NF (1 μm)	212.5 ± 53.2a
T/A plus β-NF (3 μm)	220.5 ± 50.7a
T/A plus FICZ (0.3 μm)	222.4 ± 28.5a
T/A plus FICZ (0.5 μm)	184.4 ± 19.7a
β-NF (3 μm)	1.4 ± 0.8
FICZ (0.5 μm)	1.3 ± 0.4

^a p < 0.01 versus unstimulated control.
