Induction of IFN-γ but not IL-12 in NK1.1+ PECs by RMA-S cells. PECs from mice inoculated with either RMA-S or RMA-S.Ham-2 were FACS® sorted into NK1.1+ and NK1.1− populations and analyzed for IFN-γ (a) and IL-12 (p40) transcripts (b). Competitive PCR was used for the quantitation of transcripts (see Materials and Methods), and the intensity of the bands is displayed as percent compared with a β-actin standard. In c, the serum levels of IFN-α and IFN-β were measured using DELFIA (see Materials and Methods). Induction of IFN-γ transcription is observed in intraperitoneal NK1.1+ cells but not in NK1.1− cells and is dependent on tumor MHC class I expression.
