Interference between ultrafine P90 and benzo[ a ]pyrene (BaP) in CYP1B1 induction in PBMC. Cells remained untreated or pre-stimulated with ultrafine P90 (32 μg/ml) for 30 min. Subsequently cells were stimulated with liposomes containing three different concentrations of BaP (0.1 μM, 1 μM, and 10 μM) and incubated for 3 h. (n = 7 incubations from different donors, mean ± S.D.; * p < 0.05 compared to untreated control).
