FIG. 7.

FTP-mediated IFN-γ and IL-4 responses in LN cells derived from BALB/c mice immunized with TRYP/TRYP, TRYP/Vec, or Vec/Vec. At 16 weeks after booster vaccination, in vivo recall was performed by footpad injection of 5 μg FTP 48 h prior to removal of draining LN cells. Triplicate wells containing pooled LN cells were restimulated in vitro with 10 μg/ml FTP for 72 h, and supernatants were removed for detection of IFN-γ or IL-4 by ELISA. The results (means ± standard errors) are representative of replicate experiments in which similar results were obtained.
