Cytokine expression in the spleens of BALB/c mice orally immunized with transgenic B. napus that expresses the MLC chimeric recombinant protein. Concentrations of IL-2, IL-12(p40), IFN-γ, and TNF-α were measured. Group 1, BALB/c mice fed PBS only; Group 2, BALB/c mice fed non-transformed plant; Group 3, BALB/c mice fed MLC chimeric recombinant protein. Values represent the mean ± SD (n = 3). * Significant difference between Groups 1 and 3 (P < 0.05). ^†Significant difference between Groups 2 and 3 (P < 0.05).
