First, the vast majority of non-Tregs (named conventional T cells, Tconv) were observed in the tumor stroma (CD3+ FoxP3− T cells in Fig. 1b; CD8+ T cells in Fig. 1e, serial sections), to a lesser extent in TLS (CD3+ FoxP3− T cells in Fig. 1c–f, serial sections), and rarely in tumor nests (CD3+ FoxP3- T cells in Fig. 1a; CD8+ T cells in Fig. 1d, serial sections). Here, FOXP3 is linked to neoplasm.
