FIG. 2.

IFN-γ production from NK cells cocultured with N. caninum (N.c.)-infected fibroblasts. (A) IFN-γ in supernatants of IL-2-activated NK cells cocultured for 24 h at a 10:1 rate with autologous fibroblasts infected for 36 h (filled bars), uninfected fibroblasts (shaded bars), or medium alone (open bars) were measured by ELISA. The results shown are means + SEM of two animals analyzed in triplicate, representative of three experiments. (B) As for panel A in the presence of 5 U/ml bovine rIL-12. Note the different values on the y axis. The results shown are means + SEM of two animals analyzed in triplicate representative of two experiments.
