() Ficoll-isolated human PBMC (1 × 10/sample) were stimulated with ABH at various concentrations as indicated at the bottom of the panels. After incubation for 16 h, supernatants were collected and the amounts of IL-12 p40 were determined. () PBMCs were stimulated with 0.17 ng/ml ABH for 16 h. The supernatant was collected and the amounts of IL-12 p70 were determined. (A and B) IL-12 p40 and p70 in culture supernatants were measured by ELISA. Data of IL-12 p40 and p70 shown are from four and two different donors, respectively.
