The analysis of neoantigen-specific CD8(+) T cells in tumour-bearing individuals
is challenging due to the small pool of tumour antigen-specific T cells. Here we
show that mass cytometry with multiplex combinatorial tetramer staining can
identify and characterize neoantigen-specific CD8(+) T cells in mice bearing T3
methylcholanthrene-induced sarcomas that are susceptible to checkpoint blockade
immunotherapy. Among 81 candidate antigens tested, we identify T cells restricted
to two known neoantigens simultaneously in tumours, spleens and lymph nodes in
tumour-bearing mice. High-dimensional phenotypic profiling reveals that
antigen-specific, tumour-infiltrating T cells are highly heterogeneous. We
further show that neoantigen-specific T cells display a different phenotypic
profile in mice treated with anti-CTLA-4 or anti-PD-1 immunotherapy, whereas
their peripheral counterparts are not affected by the treatments. Our results
provide insights into the nature of neoantigen-specific T cells and the effects
of checkpoint blockade immunotherapy.Immune checkpoint blockade (ICB) therapies
can unleash anti-tumour T-cell responses. Here the authors show, by integrating
MHC tetramer multiplexing, mass cytometry and high-dimensional analyses, that
neoantigen-specific, tumour-infiltrating T cells are highly heterogeneous and are
subjected to ICB modulations.
