FOXP3 and carcinoma: We identified major T/NK cell subpopulations including naive or memory T cells (Tn/Tm, CCR7 + ), regulatory T cells (Tregs, FOXP3 + ), effector T or effector memory T cells (Teff/Tem, GZMA/GZMB + ), short-lived effector cells (SLEC, KLRG1 + ), NKT cells (CD3 + NKG7 + ) as well as a population of cycling T cells (MKI67 + ), a cluster of T-carcinoma cell doublets and NK cells (Supplementary Fig. 8A, B).
