Engineered T cells targeting E7 mediate regression of human papillomavirus cancers in a murine model

T cell receptor (TCR) T cell therapy is a promising cancer treatment modality. However, its successful development for epithelial cancers may depend on the identification of high-avidity TCRs directed against tumor-restricted target antigens. The human papillomavirus (HPV) E7 antigen is an attractive therapeutic target that is constitutively expressed by HPV+ cancers but not by healthy tissues. It is unknown if genetically engineered TCR T cells...
