CD160 and neoplasm: Like the observations in tumor-naive mice (Fig. 7F), tumor-infiltrating CD27+Ly6C+ γδ T cells also expressed lower levels of NKG2A, NKp46, and IFNγ (but not CD160) in Il27ra−/− mice (Figs. 7H and EV4D), while CD160, NKG2A, NKp46, and IFNγ expression by tumor-infiltrating CD27+Ly6C− γδ T cells remained the same between WT and Il27ra−/− mice (Figs. 7H and EV4D).
