Mice immunised with oxidised mannan-MUC1 fusion protein (M-FP) develop MHC restricted CD8(+) cytotoxic T cells. We now demonstrate that in MUC1/HLA-A2 transgenic mice, IL-12 gives enhanced CTL, CTLp and tumor protection. CTLp in MUC1 transgenic mice with M-FP were 1/55,000, and with IL-12, this increased to 1/19,000, with improved tumor protection. Thus, IL-12 is important for effective CTL responses to MUC1 in transgenic mice.
