Ficoll-isolated human PBMCs were stimulated with 40 ng/ml ABH for the indicated times. RNase protection assay was performed with total RNA from stimulated PBMC. Aliquots of 10 μg of RNA were used for each determination. Lane 1, free probe; lane 2, yeast tRNA; lanes 3 and 4, unstimulated cells (–); lanes 5–8, cells stimulated with extract for the times indicated at the top of the panel. The upper panel shows IL-12p35 and p40 mRNA, and the lower panel shows L32 and GAPDH as a control. Data shown are representative of three independent experiments.
