Experimental details: Figure 1 Unfractionated PBMC contain highly serviceable, readily activated myeloid Ag-presenting cells A . Cryopreserved healthy donor PBMC derived by leukapheresis were thawed on d0, cultured overnight in RPMI 1640 with standard additives,10% heat deactivated human AB serum, 40ng/ml rhGM-CSF and 20ng/ml rhIL-4, then exposed on d1 to single or paired danger signals (pIC 50mug/ml, R848 10muM, LPS 50ng/ml, IFNgamma 2000 IU/ml). Supernatants were harvested for ELISA on d2 to determine production of IL-12 (functionally assembled IL-12p70 dimer), pg/ml, 6 million PBMC/ml. This is representative of 8 biological replicates. B . Scheme depicting Steps 1 and 2 of culture for groups receiving rhGM-CSF+R848+LPS. C . d2 analyses of PBMC cultured three different ways: (a) standard ""IL-12"" culture group (2 days prior to their initial exposure to rhIL-12 and rhIL-2); (b) ""GM"" conditioned culture group which received rhGM-CSF (40 ng/ml) on d0; (c) ""GM+R848+LPS"" group, same as ""GM"" group but also receiving R848+LPS on d1. d2 supernatants were assayed for IL-12p70 and IL-23 (BD = below detection) and resuspended PBMC were analyzed by FACS for B7.1 and HLA-DR expression within the CD33+ myeloid subpopulation.
