IFNG and neoplasm: As shown in Figure 4, CD14- PBMCs, primed with Hsp70-pulsed iDCs and challenged with iDCs pulsed with MDA-MB-231 cell extracts (tumour cell: TC) in the second stimulation [Fig. 4 Hsp70(1)/TC(2)], produced IFN-γ (pg/mL) levels at 60% and 46% of that produced by cells primed and challenged with MDA-MB-231 total cell extracts [TC(1)+TC(2)], in two individual blood donors respectively.
