In keeping with this notion, HER-2/neu (neu)-targeted vaccines, which raise strong CD8(+) T cell responses to a dominant peptide (RNEU(420-429)) in WT FVB/N mice and protect them from a neu-expressing tumor challenge, fail to do so in MMTV-neu (neu-N) transgenic mice. However, tr...
The lepidopteran-specific, insecticidal crystal proteins of Bacillus thuringiensis vary in toxicity to different species of lepidopteran larvae. We report studies of CryIA(a) and CryIA(c), two related proteins that have different degrees of toxicity to Heliothis virescens yet very similar degrees of toxicity to Manduca sexta. The amino acid differences between these proteins are located primari...
