1. Detection of neoantigen-specific T cell recognition in cancer.
Detection of neoantigen-specific T cell recognition in cancer. (A) Antigen-specific T cells in melanoma TILs identified by the combinatorial color encoding strategy using empty-loadable DS-A2 multimers. pMHC multimers for 54 A2-restricted peptides (43 neoantigens, 5 melanoma-associated cancer antigens, and 6 virus-derived antigens) were generated, each in a two-color combination. Frequency of pMHC multimer–positive cells out of total CD8+ T cells is shown as colored dots across three categories. Multimer-negative cells are plotted in gray for each pMHC combination (zero values are converted to to plot on log scale). (B) Dot plots of the antigen-specific T cell populations from (A), each is shown with indicated fluorochromes and peptide sequences. The mutated amino acid position of the neoantigens is highlighted in red.
