However, in TME, under the influence of secreted factors, γδ T-cells can be polarized; i.e., can shift from one phenotype to another, in forkhead box P3 (FOXP3)+ regulatory γδ T-cells (γδ Tregs) which display regulatory/immunosuppressive activity (Casetti et al., 2009) or in CD30+ γδ T17 cells, which secrete large amounts of IL17 and can provide the accumulation of immunosuppressive cells in the tumor and stimulate angiogenesis (Wu et al., 2014; Patil et al., 2016). Here, FOXP3 is linked to neoplasm.
