Production of LTB4 and IFN-γ in the EBV-infected PSK- and Trx80-containing cultures. (A) LTB4 in the supernatant of 24-hour-old cultures was detected by EIA. Cultures were initiated with 106/mL EBV-infected CBMCs, total and monocyte (Mo) depleted, and uninfected CBMCs. The results represent the means plus or minus SEM of 5 independent experiments. (B) IFN-γ in the supernatant of 3-day-old cultures was tested by ELISA. The results represent the means plus or minus SD of 4 independent experiments. **P < .01 compared with untreated cultures. (C) LTB4 production in cultures containing the indicated antibodies added at the initiation of cultures. The results represent the means plus or minus SEM of 3 independent experiments.
