Phenotype, specificity and avidity of antitumour CD8 T cells in melanoma.

Nature 2021 Jul 21. Epub 2021 Jul 21.

Department of Medical Oncology, Dana-Farber Cancer Institute, Boston, MA, USA.

Interactions between T cell receptors (TCRs) and their cognate tumour antigens are central to antitumour immune responses; however, the relationship between phenotypic characteristics and TCR properties is not well elucidated. Here we show, by linking the antigenic specificity of TCRs and the cellular phenotype of melanoma-infiltrating lymphocytes at single-cell resolution, that tumour specificity shapes the expression state of intratumoural CD8 T cells. Non-tumour-reactive T cells were enriched for viral specificities and exhibited a non-exhausted memory phenotype, whereas melanoma-reactive lymphocytes predominantly displayed an exhausted state that encompassed diverse levels of differentiation but rarely acquired memory properties.
