N1 - Funding Information:
We thank F. Cahill, A. Haire, H. Wylie, D. Marsh and J. Farhadi for consenting and recruiting the patients and for the acquisition of the excess skin samples. We thank the King’s Health Partners Cancer Biobank for supplying the primary tumor tissue from patients with NSCLC. We thank P. Vantourout for helpful advice and discussions and E. Theodoridis for logistical support. A.H. received support from the Francis Crick Institute, which receives core funding from Cancer Research UK (grant no. FC001093), the Medical Research Council (MRC) (grant no. FC001093) and the Wellcome Trust (grant no. FC001093). R.W. was supported by an MRC predoctoral fellowship (MR/K002627/1). D.B. was supported by funding from the Idea to Innovation (i2i) Crick translation scheme, the MRC and the University College London Hospitals NHS Foundation Trust Biomedical Research Centre. O.N. and I.Z. were supported by the Guy’s and St Thomas’ Hospital Trust Biomedical Research Centre. D.D., S.K. and M.L.I. were supported by a sponsored research agreement with Gamma Delta Therapeutics. Y.W. was supported by funding from the Wellcome Trust (220589/Z/20/Z). Figure and Extended Data Fig. were created with BioRender.com .

N2 - Checkpoint inhibition (CPI), particularly that targeting the inhibitory coreceptor programmed cell death protein 1 (PD-1), has transformed oncology. Although CPI can derepress cancer (neo)antigen-specific αβ T cells that ordinarily show PD-1-dependent exhaustion, it can also be efficacious against cancers evading αβ T cell recognition. In such settings, γδ T cells have been implicated, but the functional relevance of PD-1 expression by these cells is unclear. Here we demonstrate that intratumoral TRDV1 transcripts (encoding the TCRδ chain of Vδ1+ γδ T cells) predict anti-PD-1 CPI response in patients with melanoma, particularly those harboring below average neoantigens. Moreover, using a protocol yielding substantial numbers of tissue-derived Vδ1+ cells, we show that PD-1+Vδ1+ cells display a transcriptomic program similar to, but distinct from, the canonical exhaustion program of colocated PD-1+CD8+ αβ T cells. In particular, PD-1+Vδ1+ cells retained effector responses to TCR signaling that were inhibitable by PD-1 engagement and derepressed by CPI.
