A Cancer Vaccine Borrowed an Old Alarm
A dendritic-cell platform used existing SARS-CoV-2 helper T-cell memory to strengthen antitumor responses in preclinical models.
Summary
A dendritic-cell platform used existing SARS-CoV-2 helper T-cell memory to strengthen antitumor responses in preclinical models.
The PROTEXI platform pairs tumor antigens with helper signals derived from SARS-CoV-2 spike epitopes so immune systems primed by infection or vaccination can reinforce tumor-specific killer T cells. In mouse and humanized-mouse models of melanoma and breast cancer, the Nature Communications study reported slower tumor growth, better survival and stronger immune memory, including alongside other immunotherapies. A first-in-human sarcoma study is planned, but the current evidence is preclinical and does not show efficacy in patients; the glassware image is generic.
