Structures suggest an approach for converting weak self-peptide tumor antigens into superagonists for CD8 T cells in cancer

P Wei, KR Jordan, JD Buhrman, J Lei… - Proceedings of the …, 2021 - National Acad Sciences
Tumors frequently express unmutated self-tumor–associated antigens (self-TAAs). However,
trial results using self-TAAs as vaccine targets against cancer are mixed, often attributed to …

Alloreactive cytotoxic T cells provide means to decipher the immunopeptidome and reveal a plethora of tumor-associated self-epitopes
