Description
As an oncogene, use of HER2 vaccines in humans requires the development of HER2 immunotherapies with maximal immunologic potential, but minimal oncologic potential. To address these issues, we developed a recombinant adenoviral vector expressing a mutated HER2 inactivated for kinase function (Ad-HER2-ki). Ad-HER2-ki was highly expressed, but non-phosphorylated and elicited minimal transcription dysregulation in primary cells. In contrast, Ad-HER2-wt elicited a strong oncogenic signature associated with tumorigenesis.
