Identifying which patients will benefit most from immune checkpoint blockade (ICB) is an important clinical challenge. A study now finds that Vδ1+ γδ T cells are associated with better response to ICB in melanoma tumors with a lower neoantigen load and shows that some effector functions of PD-1+ Vδ1+ T cells are repressed after engagement of PD-1 by PD-L1.
